Assert + expect(button).toBeInTheDocument(); + }); +}); +``` + +**Patterns:** +- `describe` blocks for component/function grouping +- Nested `describe` blocks for feature grouping (e.g., "MultiSelectDropdown (Namespace Filter)") +- `it` blocks for individual test cases +- `beforeEach` for test isolation +- AAA pattern: Arrange, Act, Assert (implicit in test body) + +**Setup/Teardown:** +- Global setup: `/home/moritz/dev/spectre-via-ssh/ui/src/test/setup.ts` + - Extends Vitest expect with jest-dom matchers + - Cleanup after each test with `@testing-library/react`

+expect(button).toHaveTextContent('Exact Text'); + +// CSS classes +expect(element).toHaveClass('className'); + +// Input values +expect(input).toHaveValue('value'); + +// Function calls

+expect(result).toBeNull(); + +// Comparisons +expect(value).toBe(expected); +expect(value).toEqual(expected); // Deep equality +``` + +## Mocking + +**Framework:** Vitest `vi` module + +**Patterns:** + +**Mocking child components:** +```typescript +vi.mock('./TimeInputWithCalendar', () => ({ + TimeInputWithCalendar: ({ value, onChange, onEnter, label }: any) => ( + onChange(e.target.value)} + onKeyDown={(e) => { + if (e.key === 'Enter' && onEnter) { + e.preventDefault(); + onEnter(); + } + }} + placeholder="Time input" + aria-label={label} + /> + ), +})); +``` + +**Mocking hooks:** +```typescript +vi.mock('../hooks/useSettings', () => ({ + useSettings: () => ({ timeFormat: '24h' }), +})); + +vi.mock('../hooks/usePersistedQuickPreset', () => ({ + usePersistedQuickPreset: () => ({ preset: null, savePreset: vi.fn() }), +})); +``` + +**Mocking functions:** +```typescript +const mockOnConfirm = vi.fn(); + +beforeEach(() => { + mockOnConfirm.mockClear(); +}); + +// Later in test: +expect(mockOnConfirm).toHaveBeenCalled(); +const [arg1, arg2] = mockOnConfirm.mock.calls[0]; +``` + +**What to Mock:** +- Child components not under test (reduce complexity) +- External dependencies (API clients, browser APIs) +- Custom hooks when testing components +- Third-party libraries that don't work in test environment + +**What NOT to Mock:** +- The component being tested +- Simple utilities (test them directly) +- React itself +- Testing library utilities + +## Fixtures and Factories + +**Test Data:** +```typescript +// Inline fixtures +const defaultProps = { + currentRange: { + start: new Date('2025-01-01T10:00:00Z'), + end: new Date('2025-01-01T11:00:00Z'), + }, + onConfirm: mockOnConfirm, +}; + +// Fixed dates for time-based tests +const fixedNow = new

+``` + +**Location:** +- Fixtures defined inline in test files (no separate fixture directory) +- Constants at top of `describe` block +- Shared fixtures reused via spread operator + +## Coverage + +**Requirements:** No enforced coverage threshold + +**View Coverage:** +```bash +npm run test # Runs with coverage +# Opens: coverage/index.html +``` + +**Exclusions:** +- `node_modules/` +- `dist/`

The most severe risks involve Go's stdlib plugin versioning constraints, template mining instability with variable-starting logs, race conditions in hot-reload without atomic updates, and state loss during progressive disclosure navigation. + +**Key finding:** The stdlib `plugin` package has severe production limitations. HashiCorp's go-plugin (RPC-based) is the production-proven alternative, used by Terraform, Vault, Nomad, and Packer for 4+ years. + +--- + +## Critical Pitfalls + +Mistakes that cause rewrites or major production issues. + +### CRITICAL-1: Go Stdlib Plugin Versioning Hell + +**What goes wrong:** +Using Go's stdlib `plugin` package creates brittle deployment where plugins crash with "plugin was built with a different version of package" errors. All plugins and the host must be built with: +- Exact same Go toolchain version +- Exact same dependency versions (including transitive deps) +- Exact same GOPATH +- Exact same build flags (`-trimpath`, `-buildmode=plugin`, etc.) + +**Why it happens:** +Go's plugin system loads `.so` files into the same process space. The runtime performs strict version checking on all shared packages. Even patch version differences in dependencies cause panics. + +**Consequences:** +- Plugin updates require rebuilding ALL plugins and host +- Cannot distribute third-party plugins (users can't build with your exact toolchain) +- Go version upgrades become coordination nightmares +- Production deployment requires lock-step versioning + +**Prevention:** +Use HashiCorp's `go-plugin` instead of stdlib `plugin`: +- RPC-based: plugins run as separate processes +- Protocol versioning: increment protocol version to invalidate incompatible plugins +- Cross-language: plugins don't need to be written in Go +- Production-proven: 4+ years in Terraform, Vault, Nomad, Packer +- Human-friendly errors when version mismatches occur + +**Detection:** +Early warning signs: +- Investigating stdlib `plugin` package documentation +- Planning to distribute plugins to users +- Considering Go version upgrades with existing plugins + +**Phase mapping:** +Phase 1 (Plugin Architecture) must decide: stdlib `plugin` vs `go-plugin`.

Example: +- "cupsd shutdown succeeded" +- "irqbalance shutdown succeeded" + +These should map to template "{service} shutdown succeeded" but Drain creates separate templates because the first token differs. + +**Why it happens:** +Drain uses a fixed-depth tree where the first few tokens determine which branch to follow. When constants appear AFTER variables, the tree structure breaks down. Log messages with different variable values at the start get routed to different branches, preventing template consolidation. + +**Consequences:** +- Template explosion: thousands of unique templates for the same pattern +- Inaccurate "new pattern" detection (false positives) +- High memory usage from redundant templates +- Degraded anomaly detection (signal lost in noise) +- Production accuracy drops below 90% on variable-starting logs + +**Prevention:** +1. **Pre-tokenize with masking:** Replace known variable patterns (IPs, UUIDs, numbers) BEFORE feeding to Drain +2. **Use Drain3 with masking:** The Drain3 implementation includes built-in masking for common patterns +3. **Consider XDrain:** Uses fixed-depth forest (not tree) with majority voting for better stability +4. **Sampling + validation:** Sample 10K logs from each namespace, validate template count is reasonable (<1000 for typical app logs) +5. **Fallback detection:** If template count exceeds threshold, flag namespace for manual review + +**Detection:** +Warning signs: +- Template count growing unbounded (monitor templates-per-1000-logs metric) +- Most templates have only 1-5 instances (indicates over-fragmentation) +- "New pattern" alerts firing constantly +- High cardinality in first token position during analysis + +**Phase mapping:** +- Phase 2 (Template Mining): Algorithm selection must account for variable-starting logs +- Phase 3 (VictoriaLogs Integration): Need sampling and validation before production use +- Phase 4 (Progressive Disclosure): Template count explosion breaks aggregated view + +**Confidence:** HIGH (verified by academic papers, Drain3 documentation, production stability reports) + +**Sources:** +- [Investigating and Improving Log Parsing in Practice](https://yanmeng.github.io/papers/FSE221.pdf) +- [Drain3: Robust streaming log template miner](https://github.com/logpai/Drain3) +- [XDrain: Effective log parsing with fixed-depth forest](https://www.sciencedirect.com/science/article/abs/pii/S0950584924001514) +- [Tools and Benchmarks for Automated Log Parsing](https://arxiv.org/pdf/1811.03509) + +--- + +### CRITICAL-3: Race Conditions in Config Hot-Reload Without Atomic Swap + +**What goes wrong:** +Naive hot-reload implementations use `sync.RWMutex` to guard a config struct, then modify it in place during reload. This creates race conditions: +1. Goroutine A reads `config.VictoriaLogsURL` +2. Reload happens, sets `config.VictoriaLogsURL = newURL` +3. Goroutine A reads `config.VictoriaLogsAPIKey` (now inconsistent with URL) +4. Request goes to newURL with oldAPIKey → authentication failure + +Even with RWMutex, readers can observe partially-updated config state. + +**Why it happens:** +RWMutex only prevents concurrent reads/writes, not partial reads across field updates. If reload updates multiple fields, readers may see: +- Some old fields, some new fields (torn reads) +- Config in invalid intermediate state (e.g., URL points to prod but timeout is still dev value) + +**Consequences:** +- Intermittent request failures during config reload +- Authentication errors with mismatched credentials +- Timeouts with wrong timeout values +- Silent data corruption if config fields are interdependent +- Difficult to reproduce (timing-sensitive) + +**Prevention:** +Use **atomic pointer swap pattern**: + +```go +type Config struct { + // config fields +} + +type HotReloadable struct { + config atomic.Value // stores *Config +} + +func (h *HotReloadable) Get() *Config { + return h.config.Load().(*Config) +} + +func (h *HotReloadable) Reload(newConfig *Config) { + // Validate newConfig first + if err := newConfig.Validate(); err != nil { + log.Warn("Config validation failed, keeping old config", "error", err) + return + } + + // Single atomic swap - readers see old OR new, never partial + h.config.Store(newConfig) +} +``` + +Additional safeguards: +1. **Validate before swap:** Never store invalid config +2. **Deep copy on read if mutating:** Prevent readers from mutating shared config +3. **Version numbering:** Include config version for debugging +4. **Rollback on partial failure:** If plugin initialization fails with new config, revert to old + +**Detection:** +Warning signs: +- Planning to use `sync.RWMutex` with multi-field config struct +- Reload logic updates fields one-by-one +- No validation before applying new config +- No rollback mechanism for failed reloads + +**Phase mapping:** +Phase 1 (Config Hot-Reload) must use atomic swap from day 1.

Template miners trained on old logs fail to recognize new patterns, causing: +- Template explosion as drift occurs +- Accuracy degradation from 90%+ to <70% +- False "new pattern" alerts (actually old pattern with new format) +- Stale templates never merged with similar new ones + +**Why it happens:** +Initial clustering creates boundaries. New logs that are semantically similar but syntactically different (e.g., "ERROR: connection timeout" becomes "ERROR connection timeout" after log library upgrade) land in separate clusters. Without rebalancing, these never merge. + +**Consequences:** +- Production accuracy drops from 90% to <70% after 30-60 days +- Template count grows unbounded (memory leak) +- "New pattern" detection becomes useless (too many false positives) +- Pattern comparison vs previous window breaks (formats don't match) +- Requires manual intervention or service restart to fix + +**Prevention:** +1. **Periodic rebalancing:** Drain3's HELP implementation includes iterative rebalancing that merges similar clusters +2. **Similarity threshold tuning:** Monitor template count growth and adjust similarity threshold if growing too fast +3. **Template TTL:** Expire templates not seen in N days (configurable, default 30d) +4. **Ensemble adaptation:** Use directed lifelong learning (maintain ensemble of parsers, add new one when drift detected) +5. **Drift detection metrics:** Track templates-per-1000-logs ratio, alert if ratio exceeds threshold + +**Detection:** +Warning signs: +- Template count growing linearly over time (not plateau) +- Most templates created in last 7 days (indicates old templates not being reused) +- Monitoring Population Stability Index (PSI) shows distribution shift +- "New pattern" alerts correlate with service deployments (expected) AND with time (drift) + +**Phase mapping:** +- Phase 2 (Template Mining): Must include rebalancing mechanism from start +- Phase 3 (Monitoring): Track drift metrics (template count, PSI, creation timestamps) +- Phase 4 (Production hardening): Add template TTL and ensemble adaptation + +**Confidence:** HIGH (verified by academic research, production log analysis systems, Drain3 documentation) + +**Sources:** +- [Adaptive Log Anomaly Detection through Drift Characterization](https://openreview.net/pdf?id=6QXrawkcrX) +- [HELP: Hierarchical Embeddings-based Log Parsing](https://www.themoonlight.io/en/review/help-hierarchical-embeddings-based-log-parsing) +- [System Log Parsing with LLMs: A Review](https://arxiv.org/pdf/2504.04877) + +--- + +## Moderate Pitfalls + +Mistakes that cause delays or technical debt. + +### MODERATE-1: MCP Protocol Version Mismatch Without Graceful Degradation + +**What goes wrong:** +MCP protocol evolves rapidly (2025-03-26, 2025-06-18, 2025-11-25 releases). Plugin built against 2025-06-18 fails to connect to client supporting only 2025-03-26. Instead of graceful degradation, connection fails silently or with cryptic error. + +**Why it happens:** +MCP protocol version negotiation happens during initialization. If server declares only newer protocol version and client supports only older version, they cannot agree on common version. Without explicit handling, this manifests as connection timeout or protocol error. + +**Prevention:** +1. **Multi-version support:** Server declares all supported protocol versions: `["2025-11-25", "2025-06-18", "2025-03-26"]` +2. **Feature detection, not version checking:** Check for specific capabilities (e.g., async tasks) rather than version string +3. **Graceful fallback:** If client only supports old version, use subset of features available in that version +4. **Clear error messages:** If no common version, return human-friendly error: "Server requires MCP 2025-06-18+, client supports 2025-03-26" +5. **Version in health endpoint:** Expose supported protocol versions in status endpoint for debugging + +**Detection:** +- Planning single protocol version support +- Hard-coding protocol version checks +- No fallback for missing features +- Connection errors without version information + +**Phase mapping:** +Phase 1 (Plugin Architecture): Design plugin interface to support multiple MCP protocol versions. + +**Confidence:** MEDIUM (MCP spec documentation, production deployment reports) + +**Sources:** +- [MCP Versioning Specification](https://modelcontextprotocol.io/specification/versioning) +- [MCP 2025-11-25 Release](https://blog.modelcontextprotocol.io/posts/2025-11-25-first-mcp-anniversary/) +- [MCP Best Practices](https://modelcontextprotocol.info/docs/best-practices/) + +--- + +### MODERATE-2: Cross-Client Template Inconsistency Without Canonical Storage + +**What goes wrong:** +Two clients (IDE plugin, CLI) mine templates independently. Same log message gets template ID "a7b3c4" in IDE but "f9e2d1" in CLI. User asks "show me instances of template a7b3c4" in CLI → no results (CLI doesn't have that ID). + +**Why it happens:** +Template mining is sensitive to: +- Processing order (first-seen logs influence tree structure) +- Sampling (if sampling differently, see different representative logs) +- Algorithm parameters (similarity threshold, max depth) +- Initialization state (empty tree vs pre-populated) + +**Prevention:** +1. **Canonical storage in MCP server:** Server mines templates once, stores in local cache, serves template IDs to all clients +2. **Deterministic template IDs:** Hash normalized template string (lowercase, sorted params) → consistent ID across clients +3. **Template sync protocol:** Clients periodically fetch template mapping from MCP server +4. **Lazy mining:** Client sends raw logs to MCP server, server returns template ID (mines if new) +5. **Template versioning:** Include timestamp or version in template ID to track evolution + +**Detection:** +- Planning client-side template mining without coordination +- Using random IDs or sequential counters for templates +- No shared storage for template definitions +- Template IDs in URLs or saved queries (implies long-term identity) + +**Phase mapping:** +Phase 2 (Template Mining): Must decide storage location (MCP server vs client) +Phase 4 (Multi-client support): Cross-client consistency becomes critical + +**Confidence:** MEDIUM (distributed caching research, log analysis best practices) + +**Sources:** +- [Distributed caching with strong consistency](https://www.frontiersin.org/journals/computer-science/articles/10.3389/fcomp.2025.1511161/full) +- [Cache consistency patterns](https://redis.io/blog/three-ways-to-maintain-cache-consistency/) + +--- + +### MODERATE-3: Plugin Testing Without Process Isolation + +**What goes wrong:** +Testing plugin lifecycle (load, execute, reload, unload) in-process using Go's stdlib `plugin` package.

The primary use case is VictoriaLogs integration with intelligent log exploration using template mining and progressive disclosure UX patterns. + +Expert systems build extensible observability platforms using compile-time plugin registration (not runtime .so loading) with RPC-based process isolation. The recommended approach uses HashiCorp go-plugin for plugin lifecycle, Koanf for hot-reload configuration management, and Drain algorithm for log template mining. Critical architecture decisions include: interface-based plugin registry (avoiding Go stdlib plugin versioning hell), pipeline stages with bounded channels for backpressure, and atomic pointer swap for race-free config reloads. + +The primary risk is template mining instability with variable-starting logs, which causes template explosion and degrades accuracy from 90% to under 70%. Mitigation requires pre-tokenization with masking, periodic template rebalancing, and monitoring template growth metrics. Secondary risks include config hot-reload race conditions (prevented via atomic.Value) and progressive disclosure state loss (prevented via URL-based state). All critical risks have proven mitigation strategies from production deployments. + +## Key Findings + +### Recommended Stack + +Research identified battle-tested technologies for plugin systems and log processing, avoiding common pitfalls like Go stdlib plugin versioning constraints and Viper's case-sensitivity bugs. + +**Core technologies:** +- **HashiCorp go-plugin v1.7.0**: RPC-based plugin architecture — avoids stdlib plugin versioning hell, provides process isolation, production-proven in Terraform/Vault/Nomad +- **Koanf v2.3.0**: Hot-reload configuration management — modular design, built-in file watching, fixes Viper's case-insensitivity and bloat issues +- **LoggingDrain (Drain algorithm)**: Log template mining — O(log n) matching, handles high-volume streams, sub-microsecond performance +- **net/http (stdlib)**: VictoriaLogs client — sufficient for simple HTTP API, no custom client needed +- **Existing stack reuse**: mark3labs/mcp-go for MCP server, connectrpc for REST API, gopkg.in/yaml.v3 for config + +**Stack confidence:** HIGH overall. Only MEDIUM component is LoggingDrain library (small community), but Drain algorithm itself is HIGH confidence (proven in academic research and IBM production systems). Mitigation: algorithm is simple enough to re-implement in 200-300 LOC if library proves buggy. + +### Expected Features + +Research revealed MCP ecosystem favors minimalist tool design (10-20 tools maximum) due to context window constraints, directly influencing how plugins expose functionality and how log exploration should be surfaced. + +**Must have (table stakes):** +- Plugin discovery and lifecycle (load/unload with error isolation) +- Semantic versioning with compatibility checking +- Full-text log search with time range and field-based filtering +- Basic aggregation (count by time window, group by field, top-N queries) +- Progressive disclosure navigation (overview → aggregated → detail, max 3 levels) +- Clear MCP tool descriptions with JSON Schema inputs +- Breadcrumb navigation with state preservation + +**Should have (competitive differentiators):** +- Automatic log template mining (extract patterns without manual config) +- Category-based tool loading (load tool groups on demand, not all upfront) +- High-cardinality field search (fast search on trace_id despite millions of unique values) +- Smart defaults with SLO-first views +- MCP Resources for context (expose docs/schemas as resources, not tools) + +**Defer (v2+):** +- Novelty detection (time window comparison of patterns — requires baseline period) +- Anomaly scoring (rank logs by unusualness — complex ML implementation) +- Plugin marketplace/registry (centralized discovery — unnecessary for MVP) +- Hot reload without restart (advanced, can iterate to this) +- Network-based plugin discovery (adds deployment complexity without clear demand) + +### Architecture Approach + +The architecture uses interface-based plugin registration (compile-time, not runtime .so loading) with a pipeline processing pattern for log ingestion. Plugins implement a standard interface and register themselves in a compile-time registry. Log processing follows a staged pipeline with bounded channels for backpressure: ingestion → normalization → template mining → structuring → batching → VictoriaLogs storage. + +**Major components:** +1. **Plugin Manager** (`internal/mcp/plugins/`) — maintains registry of plugins, reads config to enable/disable, handles lifecycle (init/reload/shutdown), registers tools with MCP server +2. **VictoriaLogs Plugin** (`internal/mcp/plugins/victorialogs/`) — implements Plugin interface, manages log processing pipeline, exposes MCP tools for querying, handles template persistence +3. **Log Processing Pipeline** (`pipeline/`) — chain of stages with buffered channels: normalize → mine → structure → batch → write; backpressure via bounded channels with drop-oldest policy +4. **Template Miner** (`miner/`) — Drain algorithm implementation, builds prefix tree by token count and first token, similarity scoring for matches, WAL persistence with snapshots +5. **Configuration Hot-Reload** (`internal/config/watcher.go`) — fsnotify-based file watching, debouncing, SIGHUP signal handling, atomic pointer swap for race-free updates +6. **VictoriaLogs Client** (`client/`) — HTTP wrapper for /insert/jsonline endpoint, NDJSON serialization, retry with backoff, circuit breaker + +**Key patterns to follow:** +- Interface-based plugin registration (not runtime .so loading) +- Pipeline stages with bounded channels (prevents memory exhaustion) +- Drain-inspired template mining (O(log n) matching vs O(n) regex list) +- Atomic pointer swap for config reload (prevents torn reads) +- Template cache with WAL persistence (fast reads, durability across restarts) + +### Critical Pitfalls + +Research identified five critical pitfalls that cause rewrites or major production issues, plus several moderate pitfalls that cause delays. + +1. **Go Stdlib Plugin Versioning Hell** — Using stdlib `plugin` package creates brittle deployment where plugins crash with version mismatches. All plugins and host must be built with exact same Go toolchain, dependency versions, GOPATH, and build flags. Prevention: Use HashiCorp go-plugin (RPC-based, process isolation, production-proven). + +2. **Template Mining Instability with Variable-Starting Logs** — Drain fails when log messages start with variables instead of constants (e.g., "cupsd shutdown succeeded" vs "irqbalance shutdown succeeded" create separate templates instead of one). Causes template explosion, accuracy drops from 90% to <70%. Prevention: Pre-tokenize with masking (replace known variable patterns before feeding to Drain), use Drain3 with built-in masking, monitor template growth metrics. + +3. **Race Conditions in Config Hot-Reload** — Using sync.RWMutex with in-place field updates creates torn reads where goroutines see partial config state (old URL with new API key). Prevention: Use atomic.Value pointer swap pattern — validate entire config, then single atomic swap (readers see old OR new, never partial). + +4. **Template Drift Without Rebalancing** — Log formats evolve over time (syntactic drift), causing accuracy degradation and template explosion after 30-60 days. Prevention: Use Drain3 HELP implementation with iterative rebalancing, implement template TTL (expire templates not seen in 30d), monitor templates-per-1000-logs ratio. + +5. **UI State Loss During Progressive Disclosure** — Component-local state resets on navigation, browser back button doesn't restore context. Prevention: Encode state in URL query params from day 1 (hard to retrofit), use React Router with location.state, implement breadcrumb navigation with clickable links. + +**Moderate pitfalls:** +- MCP protocol version mismatch without graceful degradation (support multiple protocol versions) +- Cross-client template inconsistency (canonical storage in MCP server, deterministic IDs) +- VictoriaLogs live tailing without rate limiting (minimum 1s refresh, warn at >1K logs/sec) +- No config validation before hot-reload (validate and health-check before swap) + +## Implications for Roadmap + +Based on research, suggested phase structure follows dependency order identified in architecture patterns: plugin foundation must exist before integrations, log processing depends on VictoriaLogs client, template mining can be iterative, UI comes last. + +### Phase 1: Plugin Infrastructure Foundation +**Rationale:** Plugin architecture is the foundation for all integrations. Must be correct from day 1 because changing plugin system later (e.g., stdlib plugin to go-plugin) forces complete rewrite. + +**Delivers:** +- Plugin interface definition and registry +- Config loader extension for integrations.yaml +- Atomic config hot-reload with fsnotify +- Existing Kubernetes tools migrated to plugin pattern + +**Addresses (from FEATURES.md):** +- Plugin discovery and lifecycle (table stakes) +- Semantic versioning with compatibility checking (table stakes) +- Config hot-reload (competitive differentiator) + +**Avoids (from PITFALLS.md):** +- CRITICAL-1: Uses HashiCorp go-plugin, not stdlib plugin +- CRITICAL-3: Implements atomic pointer swap for config reload from start + +**Stack elements:** Koanf v2.3.0 + providers, fsnotify (transitive), HashiCorp go-plugin v1.7.0 + +**Research flags:** Standard patterns, skip additional research. Well-documented in go-plugin and Koanf documentation. + +### Phase 2: VictoriaLogs Client & Basic Pipeline +**Rationale:** Establish reliable external integration before adding complexity of template mining. Validates that log pipeline architecture works with real VictoriaLogs instance. + +**Delivers:** +- HTTP client for /insert/jsonline endpoint +- Pipeline stages (normalize, batch, write) +- Kubernetes event ingestion +- Basic VictoriaLogs plugin registration +- Backpressure with bounded channels + +**Addresses (from FEATURES.md):** +- Log ingestion and storage (prerequisite for query tools) +- Backpressure handling (reliability) + +**Avoids (from PITFALLS.md):** +- MODERATE-4: Implements rate limiting for potential live tail +- MINOR-4: Uses correct VictoriaLogs time filter patterns + +**Stack elements:** net/http (stdlib), existing Kubernetes event stream + +**Research flags:** Standard patterns, skip additional research. VictoriaLogs API is well-documented. + +### Phase 3: Log Template Mining +**Rationale:** Template mining is complex and can be iterated on. Start with basic Drain implementation, validate with production log samples, iterate on masking and rebalancing based on real data. + +**Delivers:** +- Drain algorithm implementation for template extraction +- Template cache with in-memory storage +- Template persistence (WAL + snapshots) +- Integration with log pipeline +- Template metadata in VictoriaLogs logs + +**Addresses (from FEATURES.md):** +- Automatic template mining (competitive differentiator) +- Pattern detection without manual config + +**Avoids (from PITFALLS.md):** +- CRITICAL-2: Pre-tokenization with masking for variable-starting logs +- CRITICAL-4: Periodic rebalancing mechanism (use Drain3 HELP if available, or implement TTL) +- MINOR-3: Order normalization rules correctly (IPv6 before UUID) + +**Stack elements:** LoggingDrain library (or custom implementation) + +**Research flags:** NEEDS DEEPER RESEARCH during phase planning. Drain algorithm parameters (similarity threshold, tree depth, max clusters) need tuning based on actual log patterns. Recommend `/gsd:research-phase` to: +- Sample production logs from target namespaces +- Validate template count is reasonable (<1000 for typical app) +- Tune similarity threshold (0.3-0.6 range) +- Test masking patterns with edge cases + +### Phase 4: MCP Query Tools +**Rationale:** Query tools depend on both VictoriaLogs client (Phase 2) and template mining (Phase 3). This phase exposes functionality to AI assistants via MCP. + +**Delivers:** +- `query_logs` tool with LogsQL integration +- `analyze_log_patterns` tool using template data +- VictoriaLogs plugin full registration +- Tool descriptions and JSON schemas +- MCP Resources for VictoriaLogs schema docs + +**Addresses (from FEATURES.md):** +- Full-text search with time range filtering (table stakes) +- Field-based filtering, aggregation (table stakes) +- High-cardinality field search (differentiator) +- MCP Resources for context (differentiator) + +**Avoids (from PITFALLS.md):** +- MODERATE-1: Multi-version MCP protocol support +- Tool count minimization (10-20 tools, per MCP best practices) + +**Stack elements:** Existing mark3labs/mcp-go, VictoriaLogs client from Phase 2, templates from Phase 3 + +**Research flags:** Standard MCP patterns, skip additional research. Mark3labs/mcp-go provides clear tool registration API. + +### Phase 5: Progressive Disclosure UI +**Rationale:** UI comes last because it depends on query tools (Phase 4) and benefits from real template data. Can iterate on UX based on actual usage patterns. + +**Delivers:** +- Three-level drill-down (global → aggregated → detail) +- URL-based state management +- Breadcrumb navigation +- Collapsible sections for details +- Smart defaults (SLO-first view) + +**Addresses (from FEATURES.md):** +- Progressive disclosure navigation (table stakes) +- State preservation (table stakes) +- Smart defaults with SLO-first views (differentiator) + +**Avoids (from PITFALLS.md):** +- CRITICAL-5: URL-based state from day 1 (hard to retrofit) +- MINOR-2: Limit to 3 levels maximum (global → aggregated → detail) +- MODERATE-5: Preserve context during drill-down + +**Stack elements:** Existing React frontend, React Router + +**Research flags:** Standard React patterns, skip additional research. Established SPA state management patterns. + +### Phase 6: Template Consistency & Monitoring (Optional) +**Rationale:** Cross-client consistency and drift monitoring are operational excellence features. Can defer if MVP targets single client or if template drift isn't observed in practice. + +**Delivers:** +- Canonical template storage in MCP server +- Deterministic template IDs (hash-based) +- Template drift detection metrics +- Template growth monitoring +- Health check endpoints + +**Addresses (from FEATURES.md):** +- Cross-client consistency (nice-to-have) +- Template drift detection (operational excellence) + +**Avoids (from PITFALLS.md):** +- MODERATE-2: Ensures same template IDs across clients +- Template growth monitoring (early warning for drift) + +**Research flags:** Standard patterns, skip additional research. + +### Phase Ordering Rationale + +- **Sequential dependency chain:** Plugin infrastructure (1) → VictoriaLogs client (2) → Template mining (3) → Query tools (4) → UI (5) +- **Risk-first approach:** Critical decisions (plugin system choice, config reload pattern) in Phase 1 where changes are cheapest +- **Iterative complexity:** Start simple (basic pipeline in Phase 2), add complexity (template mining in Phase 3), iterate on UX (Phase 5) +- **Validation points:** Each phase delivers independently testable functionality (Phase 2 validates VictoriaLogs integration before adding template mining complexity) +- **Pitfall avoidance:** Phase 1 prevents CRITICAL-1 (plugin system) and CRITICAL-3 (config reload), Phase 3 prevents CRITICAL-2 and CRITICAL-4 (template mining), Phase 5 prevents CRITICAL-5 (UI state) + +### Research Flags + +Phases likely needing deeper research during planning: +- **Phase 3 (Template Mining):** Complex algorithm with production-sensitive tuning. Needs `/gsd:research-phase` to sample real logs, validate template count, tune parameters (similarity threshold, tree depth, masking patterns). Research questions: What's the typical template count for our log patterns? What similarity threshold prevents explosion? Which fields need masking? + +Phases with standard patterns (skip research-phase): +- **Phase 1 (Plugin Infrastructure):** Well-documented in go-plugin and Koanf documentation, established patterns +- **Phase 2 (VictoriaLogs Client):** VictoriaLogs HTTP API is well-documented, standard Go HTTP client patterns +- **Phase 4 (MCP Query Tools):** Mark3labs/mcp-go provides clear API, existing MCP tools in codebase as reference +- **Phase 5 (Progressive Disclosure UI):** Standard React/SPA patterns, URL state management well-established + +## Confidence Assessment + +| Area | Confidence | Notes | +|------|------------|-------| +| Stack | HIGH | HashiCorp go-plugin (4+ years production), Koanf (stable v2), VictoriaLogs (official docs). Only MEDIUM: LoggingDrain library (small community, but algorithm is proven). | +| Features | HIGH | MCP patterns from 2026 best practices, progressive disclosure from UX research, log exploration features from VictoriaLogs docs and competitor analysis. MEDIUM: VictoriaLogs-specific query capabilities (not all features detailed in web search). | +| Architecture | HIGH | Existing codebase analysis provides foundation, external patterns verified with production examples (pipeline stages, Drain algorithm, atomic swap pattern). Interface-based plugin registry is idiomatic Go. | +| Pitfalls | MEDIUM-HIGH | Critical pitfalls verified with official sources (Go issue tracker for stdlib plugin, academic papers for Drain limitations, Go docs for atomic operations). MEDIUM: Progressive disclosure pitfalls (UX research from web only). | + +**Overall confidence:** HIGH + +Research covers all critical decisions with high-confidence sources. The one MEDIUM component (LoggingDrain library) has clear mitigation (re-implement algorithm if needed). Recommended phase order follows verified dependency patterns. + +### Gaps to Address + +**LoggingDrain library maturity (MEDIUM confidence):** Small community (16 stars), recent but limited production reports. Mitigation: Phase 3 should include spike to validate library works as expected. If bugs found, Drain algorithm is simple enough to implement in-house (200-300 LOC for core logic per research). + +**VictoriaLogs query syntax details (MEDIUM confidence):** Web search provided high-level capabilities, but full LogsQL syntax not exhaustively documented in search results. Mitigation: Consult VictoriaLogs API documentation directly during Phase 4 implementation. No blocking risk — basic query patterns are well-documented. + +**Template mining parameter tuning (production-dependent):** Optimal values for similarity threshold, tree depth, and max clusters depend on actual log patterns in target environment. Mitigation: Phase 3 planning should include `/gsd:research-phase` to sample production logs and validate parameters. Research identified ranges (similarity 0.3-0.6, depth 4-6) but exact values need empirical testing. + +**Cross-client template consistency requirements (unclear):** Research identified the risk, but MVP scope doesn't clarify if multiple clients will access templates simultaneously. Mitigation: Phase 6 is marked optional, can prioritize based on actual multi-client usage patterns observed in Phases 4-5. + +## Sources + +### Primary (HIGH confidence) +- [HashiCorp go-plugin v1.7.0 on Go Packages](https://pkg.go.dev/github.com/hashicorp/go-plugin) — plugin architecture +- [Koanf v2.3.0 GitHub releases](https://github.com/knadh/koanf/releases) — config management +- [VictoriaLogs Official Documentation](https://docs.victoriametrics.com/victorialogs/) — log storage and querying +- [Drain3 algorithm](https://github.com/logpai/Drain3) — template mining +- [Go issue tracker (#27751, #31354)](https://github.com/golang/go/issues) — stdlib plugin limitations +- [MCP Protocol Specification](https://modelcontextprotocol.io/specification/) — MCP patterns +- [Semantic Versioning 2.0.0](https://semver.org/) — versioning +- [Nielsen Norman Group - Progressive Disclosure](https://www.nngroup.com/articles/progressive-disclosure/) — UX patterns + +### Secondary (MEDIUM confidence) +- [Klavis - MCP Design Patterns](https://www.klavis.ai/blog/less-is-more-mcp-design-patterns-for-ai-agents) — tool count guidance +- [LoggingDrain GitHub](https://github.com/PalanQu/LoggingDrain) — Go implementation +- [Viper vs Koanf comparison](https://itnext.io/golang-configuration-management-library-viper-vs-koanf-eea60a652a22) — config library trade-offs +- [Investigating and Improving Log Parsing in Practice](https://yanmeng.github.io/papers/FSE221.pdf) — template mining pitfalls +- [Adaptive Log Anomaly Detection through Drift](https://openreview.net/pdf?id=6QXrawkcrX) — template drift research +- [React State Management 2025](https://www.developerway.com/posts/react-state-management-2025) — SPA state patterns + +### Tertiary (LOW confidence) +- Various blog posts and Medium articles — supporting evidence for best practices, cross-validated with official sources + +--- +*Research completed: 2026-01-20* +*Ready for roadmap: yes* From 9d1ba7f5a9115af6d577fd9a3f28b16e922a6055 Mon Sep 17 00:00:00 2001 From: Moritz Johner Date: Wed, 21 Jan 2026 00:13:34 +0100 Subject: [PATCH 005/342] docs: define v1 requirements MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 30 requirements across 6 categories 8 requirements deferred to v2 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- .planning/REQUIREMENTS.md | 135 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 135 insertions(+) create mode 100644 .planning/REQUIREMENTS.md diff --git a/.planning/REQUIREMENTS.md b/.planning/REQUIREMENTS.md new file mode 100644 index 0000000..13441d8 --- /dev/null +++ b/.planning/REQUIREMENTS.md @@ -0,0 +1,135 @@ +# Requirements: Spectre MCP Plugin System + VictoriaLogs Integration + +**Defined:** 2026-01-20 +**Core Value:** Enable AI assistants to explore logs progressively—starting from high-level signals, drilling into patterns, and viewing raw logs only when context is narrow. + +## v1 Requirements + +Requirements for initial release.

Comprehensive unit tests including concurrent access verification +- `internal/config/integration_loader.go` - Config loader using Koanf v2 to read and validate YAML integration files +- `internal/config/integration_loader_test.go` - Tests covering valid/invalid configs, missing files, and YAML syntax errors + +## Decisions Made + +**1. Factory registry uses global default instance with package-level convenience functions** +- Rationale: Simplifies integration registration - packages can call `integration.RegisterFactory()` directly without managing registry instances +- Pattern: `RegisterFactory(type, factory)` and `GetFactory(type)` delegate to global `defaultRegistry` + +**2. Koanf v2 requires UnmarshalWithConf with Tag: "yaml" for struct tag support** +- Rationale: Default `Unmarshal()` doesn't respect yaml struct tags in Koanf v2 - fields came back empty +- Fix: Use `k.UnmarshalWithConf("", &config, koanf.UnmarshalConf{Tag: "yaml"})` to enable yaml tag parsing + +**3. Both factory and instance registries use sync.RWMutex for thread-safe concurrent access** +- Rationale: Multiple goroutines may read registries simultaneously (Get/List), but writes (Register) need exclusive access +- Pattern: RWMutex allows concurrent reads while ensuring thread-safe writes + +**4. Registry.Register returns error for duplicate names and empty strings** +- Rationale: Duplicate names would cause ambiguity in instance lookup; empty names are invalid identifiers +- Error messages include the duplicate name for clear debugging + +## Deviations from Plan + +### Auto-fixed Issues + +**1.

[Rule 3 - Blocking] Fixed Koanf UnmarshalWithConf to specify yaml tag** +- **Found during:** Task 3 (testing config loader) +- **Issue:** `k.Unmarshal("", &config)` returned struct with empty fields - Koanf v2 doesn't default to yaml tags +- **Fix:** Changed to `k.UnmarshalWithConf("", &config, koanf.UnmarshalConf{Tag: "yaml"})` +- **Files modified:** internal/config/integration_loader.go +- **Verification:** All config loader tests pass, fields correctly populated +- **Committed in:** cd9579e (Task 3 commit) + +--- + +**Total deviations:** 2 auto-fixed (1 bug, 1 blocking) +**Impact on plan:** Both auto-fixes necessary for correct operation.

Don't duplicate Phase 1 logic; rely on the file watcher to trigger reloads automatically. + +## Common Pitfalls + +### Pitfall 1: Non-Atomic Config Writes Leading to Corruption +**What goes wrong:** Using `os.WriteFile` directly can result in partial writes if process crashes mid-write, leaving invalid YAML that breaks server startup. +**Why it happens:** Direct writes are not atomic—kernel may flush data incrementally, and power loss or crash leaves incomplete file. +**How to avoid:** Always use temp-file-then-rename pattern: +1. Write to temp file in same directory (ensures same filesystem for atomic rename) +2. Call `fsync()` or close file to flush to disk +3. Use `os.Rename()` which is atomic on POSIX systems +4. Cleanup temp file if rename fails +**Warning signs:** Config corruption after server crashes, users report "invalid schema_version" errors after system restarts + +### Pitfall 2: Race Condition Between API Write and Watcher Reload +**What goes wrong:** API handler writes config, immediately tries to read updated state from Manager registry, but watcher hasn't reloaded yet (500ms debounce). +**Why it happens:** File watcher has deliberate 500ms debounce to coalesce rapid changes (Phase 1 design). API response happens before hot-reload completes. +**How to avoid:** +- Return the requested state immediately from API (don't query Manager) +- Document that integration status updates may take up to 1 second +- Add `/api/config/integrations/{name}/status` endpoint to poll actual runtime state if needed +**Warning signs:** UI shows "Healthy" status immediately after adding integration, then switches to "Degraded" 1 second later + +### Pitfall 3: No Validation Before Test Connection +**What goes wrong:** User submits config with invalid URL format to test endpoint, integration library panics trying to connect, brings down API server. +**Why it happens:** Test endpoint receives arbitrary config without pre-validation, passes directly to integration factory. +**How to avoid:** +- Run `IntegrationsFile.Validate()` on test payload before creating integration instance +- Use request timeout context for test connections (5 second max) +- Wrap integration creation/test in recover() to catch panics +- Return structured error response with validation failures +**Warning signs:** API server crashes when user clicks "Test Connection" with malformed config + +### Pitfall 4: Modal Focus Management Breaking Accessibility +**What goes wrong:** Modal opens but focus remains on background page, keyboard users can't access modal controls, screen readers don't announce modal. +**Why it happens:** React portals render outside normal component tree, browser doesn't automatically manage focus. +**How to avoid:** +- Set `ref` on first interactive element (input or button), call `focus()` in useEffect +- Add `role="dialog"` and `aria-modal="true"` to modal container +- Trap focus within modal (prevent Tab key from escaping) +- Return focus to trigger element on close +- Handle Escape key to close modal +**Warning signs:** Keyboard users report can't access modal, Tab key moves focus to background page + +### Pitfall 5: Missing Error Boundaries Around Integration Forms +**What goes wrong:** Integration config form throws error (malformed JSON in config field), React unmounts entire IntegrationsPage, user sees blank screen. +**Why it happens:** No error boundary wrapping dynamic form components, React propagates error up to root. +**How to avoid:** +- Wrap `` in ErrorBoundary component (already exists in `ui/src/components/Common/ErrorBoundary.tsx`) +- Provide fallback UI with error message and "Close" button +- Log error details to console for debugging +**Warning signs:** White screen when user interacts with integration config, React error in console + +## Code Examples + +Verified patterns from existing codebase and standard practices: + +### REST Handler Registration Pattern +```go +// Source: internal/api/handlers/register.go (existing

Runtime health status comes from manager's instance registry. +- **Implementation:** HandleList and HandleGet query registry.Get() and call Health() with 2s timeout context. + +**3. Test endpoint validates then attempts connection** +- **Rationale:** UI "Test Connection" button needs to validate config and try starting integration without persisting. +- **Implementation:** Create temporary IntegrationsFile for validation, use factory to create instance, call Start() with 5s timeout, check Health(), clean up with Stop(). + +**4.

Define extraVolumeMounts and extraArgs fields + +## Decisions Made + +**1. Default integrations config to "integrations.yaml" with auto-create** +- **Rationale:** Better UX - no manual file creation required. Server starts immediately with working config. +- **Implementation:** Default flag value "integrations.yaml", check file existence on startup, create with schema_version: v1 if missing. + +**2. Static file handler excludes /api/* paths** +- **Rationale:** API routes registered first, but catch-all static handler was serving HTML for /api/* paths. +- **Implementation:** Early return in static handler when path starts with /api/, allowing API routes to handle requests. + +**3. /api/config/integrations/test endpoint for unsaved integrations** +- **Rationale:** UI "Test Connection" needs to validate and test integration before saving to config file. +- **Implementation:** POST /test endpoint validates config, creates temporary instance, attempts Start(), returns health status. + +**4. VictoriaLogs integration placeholder implementation** +- **Rationale:** UI needed concrete integration type for testing. Plan 03-01 will build full implementation. +- **Implementation:** Minimal Integration interface implementation with health check returning "not_started" status. + +**5. Health status 'not_started' displayed as gray 'Unknown'** +- **Rationale:** Better UX - "Unknown" clearer than technical "not_started" state. +- **Implementation:** Map 'not_started' to gray dot + "Unknown" label in IntegrationTable status rendering. + +**6. Helm chart supports extraVolumeMounts and extraArgs** +- **Rationale:** Production deployments need to mount integrations.yaml as ConfigMap and pass --integrations-config flag. +- **Implementation:** Template extraVolumeMounts in deployment.yaml, extraArgs appended to container args. + +## Deviations from Plan + +### Auto-fixed Issues During Human Verification + +**1.

[Rule 2 - Missing Critical] Default integrations-config path with auto-create** +- **Found during:** Task 2 (Human verification - server startup) +- **Issue:** --integrations-config required manual flag every time, file must exist or server crashes +- **Fix:** Set default value "integrations.yaml", check existence on startup, create with schema_version: v1 if missing +- **Files modified:** cmd/spectre/commands/server.go +- **Verification:** ./spectre server starts without flags, creates integrations.yaml automatically +- **Committed in:** cf17dc0 (fix: default integrations config path and auto-create file) + +**5. [Rule 2 - Missing Critical] VictoriaLogs integration implementation** +- **Found during:** Task 2 (Human verification - integration type testing) +- **Issue:** UI dropdown has "VictoriaLogs" type but no implementation existed - can't test integration flow +- **Fix:** Created internal/integration/victorialogs/victorialogs.go with placeholder Start/Stop/Health methods +- **Files modified:** internal/integration/victorialogs/victorialogs.go, cmd/spectre/commands/server.go (factory registration) +- **Verification:** Can add VictoriaLogs integration via UI, server doesn't panic +- **Committed in:** 7a335d5 (feat: add VictoriaLogs integration) + +**6. [Rule 1 - Bug] Fixed health status display for 'not_started' state** +- **Found during:** Task 2 (Human verification - status column) +- **Issue:** Health status 'not_started' from VictoriaLogs placeholder showed no status indicator in table +- **Fix:** Added case for 'not_started' → gray dot + "Unknown" label +- **Files modified:** ui/src/components/IntegrationTable.tsx +- **Verification:** Table shows gray "Unknown" status for VictoriaLogs integration +- **Committed in:** 7a335d5 (feat: add VictoriaLogs integration and fix health status display) + +**7. [Rule 2 - Missing Critical] Helm chart extraVolumeMounts and extraArgs** +- **Found during:** Task 2 (Human verification - deployment planning) +- **Issue:** Helm chart has no way to mount integrations.yaml ConfigMap or pass --integrations-config flag +- **Fix:** Added extraVolumeMounts and extraArgs to deployment.yaml template and values.yaml +- **Files modified:** chart/templates/deployment.yaml, chart/values.yaml +- **Verification:** Helm template renders correctly with extraVolumeMounts and extraArgs +- **Committed in:** 722a65c (feat(chart): add extraVolumeMounts and extraArgs to MCP container) + +--- + +**Total deviations:** 7 auto-fixed (3 bugs, 4 missing critical functionality) +**Impact on plan:** All fixes necessary for correct operation and testability.

The research confirms that VictoriaLogs provides well-documented HTTP endpoints for querying logs with LogsQL syntax, histogram/aggregation APIs for time-series data, and JSON line-based responses that are straightforward to parse in Go. + +The standard Go ecosystem provides all necessary components: `net/http` for the client with proper connection pooling, `context` for timeout control, buffered channels for backpressure handling, and `github.com/prometheus/client_golang` for metrics instrumentation (already in the project dependencies via transitive inclusion). + +Key architectural decisions are validated by the research: structured parameters instead of raw LogsQL prevent injection issues and simplify query construction; bounded channels (1000-item buffer) provide natural backpressure without custom logic; batch sizes of 100 items align with common Go batching patterns; and 30-second query timeouts are standard for production HTTP clients. + +**Primary recommendation:** Use VictoriaLogs `/select/logsql/query` endpoint for log retrieval, `/select/logsql/hits` for histograms, and `/select/logsql/stats_query` for aggregations. Implement structured query builders that construct LogsQL from K8s-focused parameters (namespace, pod, container, level).

The Drain algorithm uses a fixed-depth parse tree to achieve O(log n) matching performance and can extract templates from streaming logs in real-time. Two primary Go implementations exist: `github.com/faceair/drain` (more mature) and `github.com/PalanQu/LoggingDrain` (newer, performance-focused). The algorithm requires careful parameter tuning (similarity threshold, tree depth, max children) to balance between creating too many templates (template explosion) and merging unrelated logs. + +**Key technical challenges identified:** +1. **Template explosion** from variable-starting logs (e.g., "cupsd shutdown succeeded", "irqbalance shutdown succeeded" create separate branches) +2. **Template drift** over time as log formats evolve without rebalancing +3. **Kubernetes-specific normalization** for pod names with dynamic suffixes (deployment-abc123-xyz45) +4. **JSON log handling** requires extracting message field before templating to avoid structure-based clustering + +**Primary recommendation:** Use `github.com/faceair/drain` as the foundation with custom extensions for Kubernetes-aware masking, post-clustering variable normalization, and periodic template merging.

Kubernetes-specific: Detect `--` pattern, replace with `` placeholder +3. Max children parameter: Limit branches per node to force wildcard grouping (maxChildren=100 recommended) + +**Warning signs:** +- Template count grows linearly with log volume +- Most templates have count=1 or count=2 +- Memory usage grows unbounded + +**Sources:** [Drain algorithm limitations](https://github.com/logpai/Drain3), [Variable-starting log handling](https://arxiv.org/pdf/2110.15473) + +### Pitfall 2: Over-Aggressive Similarity Threshold + +**What goes wrong:** Similarity threshold too high (e.g., 0.7) merges unrelated logs into the same template + +**Example with sim_th=0.7:** +``` +"user login succeeded" +"user login failed" +``` +These are 85% similar and get merged, losing critical distinction between success/failure. + +**Why it happens:** Drain's similarity threshold is token-based: `similar_tokens / total_tokens`. High threshold merges logs that differ in only 1-2 tokens. + +**How to avoid:** +1. Start with sim_th=0.4 (default) for structured logs +2. For messy/unstructured logs, increase to 0.5-0.6 +3. User decision: Include log level in template - `INFO: user login` vs `ERROR: user login` are different templates +4.

Auto-merge similar templates: Use normalized edit distance >0.7 as merge threshold +3. Count-based pruning: Remove templates with <10 occurrences (rare edge cases) +4.

Drain configuration defaults (DrainConfig)** +- **Decision:** Use sim_th=0.4, tree depth=4, maxChildren=100 as defaults +- **Rationale:** Research-recommended values for structured Kubernetes logs. sim_th=0.4 balances between over-clustering (too few templates) and template explosion (too many). Tree depth=4 is minimum recommended (3) plus one for safety. maxChildren=100 prevents branch explosion from variable-starting logs. + +**2. Namespace-scoped template IDs** +- **Decision:** Template IDs generated from SHA-256(namespace|pattern) composite key +- **Rationale:** Same log pattern in different namespaces represents different semantics in multi-tenant environments. Scoping prevents cross-namespace template pollution while maintaining stable IDs for cross-client consistency (requirement MINE-03). + +**3.

d870b38f26ef5f878d0ec52d8b3ffad02338f2ee Mon Sep 17 00:00:00 2001 From: Moritz Johner Date: Wed, 21 Jan 2026 15:22:10 +0100 Subject: [PATCH 073/342] feat(04-03): implement periodic persistence with atomic writes - PersistenceManager handles snapshot creation and restoration - Snapshots saved to JSON every 5 minutes (configurable interval) - Atomic writes using temp-file-then-rename pattern (POSIX atomicity) - Schema versioning with version=1 for future migrations - Load() restores templates from JSON snapshot on startup - Start() runs periodic snapshot loop with graceful shutdown - Stop() triggers final snapshot before exit - Human-readable JSON format with indentation for debugging - Comprehensive test coverage: empty store, with data, atomic writes, corrupted JSON, version checks, roundtrip serialization, periodic snapshots, stop behavior Snapshots survive server restarts and prevent data loss on crashes (max 5 minutes of templates lost per design decision) ---

Initial load still fails fast | -| Manager validates integration versions on startup (PLUG-06) | 01-04 | Semantic version comparison using hashicorp/go-version | -| Failed instance start marked as degraded, not crash server | 01-04 | Resilience pattern - server continues with other instances | -| Health checks auto-recover degraded instances | 01-04 | Every 30s (configurable), calls Start() for degraded instances | -| Config reload triggers full restart with re-validation | 01-04 | Stop all → clear registry → re-validate versions → start new | -| Manager registered as lifecycle component | 01-04 | No dependencies, follows existing lifecycle.Manager pattern | -| Atomic writes prevent config corruption on crashes | 02-01 | Temp-file-then-rename ensures readers never see partial writes (POSIX atomicity) | -| Health status enriched from manager registry in real-time | 02-01 | Config file only has static data - runtime status from registry.Get().Health() | -| Test endpoint validates and attempts connection with 5s timeout | 02-01 | UI "Test Connection" needs to validate config without persisting | -| Panic recovery in test endpoint | 02-01 | Malformed configs might panic - catch with recover() and return error message | -| Path parameters extracted with strings.TrimPrefix | 02-01 | Codebase uses stdlib http.ServeMux - follow existing patterns | -| Default --integrations-config to "integrations.yaml" with auto-create | 02-03 | Better UX - no manual file creation required, server starts immediately | -| Static file handler excludes /api/* paths | 02-03 | Prevents API route conflicts - static handler returns early for /api/* | -| /api/config/integrations/test endpoint for unsaved integrations | 02-03 | Test connection before saving to config file | -| VictoriaLogs integration placeholder for UI testing | 02-03 | Enables end-to-end testing, full implementation in Phase 3 | -| Health status 'not_started' displayed as gray 'Unknown' | 02-03 | Better UX - clearer than technical state name | -| Helm chart supports extraVolumeMounts and extraArgs | 02-03 | Production deployments need to mount config as ConfigMap | -| IntegrationModal uses React portal for rendering at document.body | 02-02 | Proper z-index stacking, avoids parent container constraints | -| Focus trap cycles Tab between focusable elements in modal | 02-02 | Accessibility - keyboard navigation stays within modal context | -| Delete button only in edit mode with confirmation dialog | 02-02 | Prevents accidental deletes, clear separation add vs edit modes | -| Test Connection allows save even if test fails | 02-02 | Supports pre-staging - user can configure before target is reachable | -| Empty state shows tiles, table replaces tiles when data exists | 02-02 | Progressive disclosure - simple empty state, functional table when needed | -| Name field disabled in edit mode | 02-02 | Name is immutable identifier - prevents breaking references | -| Inline CSS-in-JS following Sidebar.tsx patterns | 02-02 | Consistent with existing codebase styling approach | -| LogsQL exact match operator is := not = | 03-01 | VictoriaLogs LogsQL syntax for precise field matching | -| Always include _time filter in queries | 03-01 | Prevents full history scans - default to last 1 hour when unspecified | -| Read response body to completion with io.ReadAll | 03-01 | Critical for HTTP connection reuse - even on error responses | -| MaxIdleConnsPerHost set to 10 (up from default 2) | 03-01 | Prevents connection churn under load for production workloads | -| Use RFC3339 for VictoriaLogs timestamps | 03-01 | ISO 8601-compliant time format for API requests | -| Empty field values omitted from LogsQL queries | 03-01 | Cleaner queries - only include non-empty filter parameters | -| Bounded channel with size 1000 provides natural backpressure | 03-02 | Blocking send when full prevents memory overflow without explicit flow control | -| No default case in Ingest select - intentional blocking | 03-02 | Prevents data loss (alternative would be to drop logs) | -| Batch size fixed at 100 entries | 03-02 | Consistent memory usage and reasonable HTTP payload size | -| 1-second flush ticker for partial batches | 03-02 | Prevents logs from stalling indefinitely while waiting for full batch | -| BatchesTotal counter tracks log count, not batch count | 03-02 | Increments by len(batch) for accurate throughput metrics | -| ConstLabels with instance name for metrics | 03-02 | Enables multiple VictoriaLogs pipeline instances with separate metrics | -| Pipeline errors logged and counted but don't crash | 03-02 | Temporary VictoriaLogs unavailability doesn't stop processing | -| Client, pipeline, metrics created in Start(), not constructor | 03-03 | Lifecycle pattern - heavy resources only created when integration starts | -| Failed connectivity test doesn't block startup | 03-03 | Degraded state with auto-recovery via health checks | -| 30-second query timeout for VictoriaLogs client | 03-03 | Balance between slow LogsQL queries and user patience | -| ValidateMinimumDuration skips validation for zero time ranges | 03-04 | Zero ranges use default 1-hour duration, validation not needed | -| BuildLogsQLQuery returns empty string on validation failure | 03-04 | Explicit failure clearer than logging/clamping; avoids silent behavior changes | -| 15-minute minimum time range hardcoded per VLOG-03 | 03-04 | Protects VictoriaLogs from excessive query load; no business need for configuration | -| DrainConfig uses sim_th=0.4, tree depth=4, maxChildren=100 | 04-01 | Research-recommended defaults for structured logs; balances clustering vs explosion | -| Templates scoped per-namespace with composite key | 04-01 | Multi-tenancy - same pattern in different namespaces has different semantics | -| SHA-256 hashing for template IDs | 04-01 | Deterministic, collision-resistant IDs for cross-client consistency (MINE-03) | -| Linear search for template lookup | 04-01 | Target <1000 templates per namespace; premature optimization unnecessary | -| JSON message field extraction with fallback order | 04-02 | Try message, msg, log, text, _raw, event - covers most frameworks while allowing structured event logs | -| Masking happens AFTER Drain clustering | 04-02 | Preserves Drain's structure detection before normalizing variables (user decision) | -| HTTP status codes preserved in templates | 04-02 | "returned 404" vs "returned 500" must stay distinct for debugging (user decision) | -| Kubernetes pod/replicaset names masked with | 04-02 | Dynamic K8s resource names (deployment-replicaset-pod format) unified for stable templates | -| File path regex without word boundaries | 04-02 | Word boundaries don't work with slash separators; removed for correct full-path matching | -| Pattern normalization for stable template IDs | 04-03 | All placeholders (, , <*>, etc.) normalized to for ID generation; semantic patterns preserved for display | -| Per-namespace Drain instances in TemplateStore | 04-03 | Namespace isolation with separate clustering state; each namespace gets own DrainProcessor | -| Deep copy templates on retrieval | 04-03 | GetTemplate/ListTemplates return copies to prevent external mutation of internal state | -| Load errors don't crash server | 04-03 | Corrupted snapshots logged but server continues with empty state; resilience over strict validation | -| Failed snapshots don't stop periodic loop | 04-03 | Snapshot errors logged but don't halt persistence manager; lose max 5 minutes on crash (user decision) | -| Atomic writes for snapshots using temp-file-then-rename | 04-03 | POSIX atomicity prevents corruption; readers never see partial writes | -| Double-checked locking for namespace creation | 04-03 | Fast read path for existing namespaces, slow write path with recheck for thread-safe lazy initialization | -| Default rebalancing config: prune threshold 10, merge interval 5min, similarity 0.7 | 04-04 | Prune threshold catches rare but important patterns; 5min matches persistence; 0.7 for loose clustering per CONTEXT.md | -| Namespace lock protects entire Drain.Train() operation | 04-04 | Drain library not thread-safe; race condition fix - lock before Train() not after | -| Existing test suite organization kept as-is | 04-04 | Tests already comprehensive at 85.2% coverage; better organized than plan suggested (rebalancer_test.go vs store_test.go) | -| MCPToolRegistry uses generic JSON schema | 05-01 | Integration handlers validate their own arguments; keeps adapter simple and flexible | -| RegisterTools() called for all instances including degraded | 05-01 | Degraded backends can still expose tools that return service unavailable; AI can discover available tools | -| NewManagerWithMCPRegistry for backward compatibility | 05-01 | Existing code works unchanged; only MCP-enabled servers use new constructor | -| Tool registration errors don't fail startup | 05-01 | Resilience - one integration's failure shouldn't crash server; logged for debugging | -| Level field used for severity filtering (error/warn) | 05-02 | Simpler than message keyword detection; graceful fallback if field missing | -| Empty namespace labeled as "(no namespace)" | 05-02 | Clearer than empty string for AI assistants identifying unlabeled logs | -| Namespaces sorted by total count descending | 05-02 | Progressive disclosure - show highest volume namespaces first | -| ToolContext pattern for shared client/logger/instance | 05-02 | Consistent context passing across all MCP tool Execute methods | -| CompareTimeWindows compares by Pattern not ID | 05-03 | Semantic novelty detection - "this log message never appeared before" regardless of namespace | -| Per-instance template store (not global) | 05-03 | Different VictoriaLogs instances have different log characteristics; independent mining | -| Stateless template mining per query | 05-03 | TemplateStore ephemeral (created in Start, cleared in Stop); no persistence for on-demand queries | -| Logs tool default limit 100, max 500 | 05-04 | Prevents AI assistant context overflow with sensible defaults and hard limits | -| Truncation flag instead of pagination | 05-04 | CONTEXT.md specified "no pagination"; truncation flag guides AI to narrow time range or use patterns tool | -| Integration manager runs in MCP server command | 05-04 | MCP server separate process from main server, needs own integration manager for tool registration | -| All three tools registered together in RegisterTools() | 05-04 | Tools work as progressive disclosure system, registered as unit with all-or-nothing lifecycle | -| Sampling threshold = targetSamples * 10 | 05-03 | Default 500 logs triggers sampling; balances accuracy with performance for high-volume namespaces | -

Context decision: SSE transport was chosen, but `mcp-go` documentation reveals SSE is deprecated as of MCP spec 2025-03-26 in favor of StreamableHTTP. **Recommendation: Use StreamableHTTP transport instead of SSE** - it's the current standard and already implemented in existing `mcp.go` command. + +3. **Integration Strategy:** Minimal code changes required. The existing integration manager (internal/integration/manager.go) can be passed to the MCP server via `MCPToolRegistry` adapter.

Lifecycle manager handles component shutdown in reverse dependency order with per-component timeout (currently 30s, will override to 10s per requirements). + +**Primary recommendation:** Use StreamableHTTP transport (already in use) instead of SSE.

Go 1.22+ supports method-specific routing on same path. + +**When to use:** Consolidating multiple services on one port. + +**Example structure:** +```go +// Source: internal/apiserver/routes.go pattern + StreamableHTTP pattern +router := http.NewServeMux() + +// REST API routes +router.Handle("/api/v1/timeline", timelineHandler) +router.HandleFunc("/health", healthHandler) + +// MCP endpoint (StreamableHTTP) +mcpServer := server.NewStreamableHTTPServer(spectreServer.GetMCPServer(), + server.WithEndpointPath("/v1/mcp"), + server.WithStateLess(true), +) +router.Handle("/v1/mcp", mcpServer) + +// Static UI (catch-all, must be last) +router.HandleFunc("/", serveStaticUI) + +// Wrap with CORS middleware +handler := corsMiddleware(router) +httpServer := &http.Server{Addr: ":8080", Handler: handler} +``` + +### Pattern 3: MCP Tool Registry Adapter +**What:** Integration manager calls `RegisterTool()` on `MCPToolRegistry` which adapts to mcp-go's `AddTool()` method. + +**When to use:** Integrations need to expose tools via MCP dynamically. + +**Example from existing code:** +```go +// Source: internal/mcp/server.go (lines 369-429) +type MCPToolRegistry struct { + mcpServer *server.MCPServer +} + +func (r *MCPToolRegistry) RegisterTool(name string, handler integration.ToolHandler) error { + // Adapter: integration.ToolHandler -> mcp.CallToolRequest + adaptedHandler := func(ctx context.Context, request mcp.CallToolRequest) (*mcp.CallToolResult, error) { + args, _ := json.Marshal(request.Params.Arguments) + result, err := handler(ctx, args) + if err != nil { + return mcp.NewToolResultError(fmt.Sprintf("Tool execution failed: %v", err)), nil + } + resultJSON, _ := json.MarshalIndent(result, "", " ") + return mcp.NewToolResultText(string(resultJSON)), nil + } + + mcpTool := mcp.NewToolWithRawSchema(name, "", schemaJSON) + r.mcpServer.AddTool(mcpTool, adaptedHandler) + return nil +} +``` + +### Pattern 4: Graceful Shutdown with Context Timeout +**What:** Use `signal.NotifyContext` to create cancellable context, then give each component its own timeout for graceful stop. + +**When to use:** Multi-component server needs coordinated shutdown. + +**Example from existing lifecycle manager:** +```go +// Source: internal/lifecycle/manager.go (lines 236-284) +// Setup signal handling +sigChan := make(chan os.Signal, 1) +signal.Notify(sigChan, syscall.SIGINT, syscall.SIGTERM) + +// Wait for signal +<-sigChan +logger.Info("Shutdown signal received") +cancel() // Cancel main context + +// Stop each component with its own timeout +shutdownCtx, cancel := context.WithTimeout(context.Background(), 10*time.Second) +defer cancel() + +for _, component := range toStop { + componentCtx, cancel := context.WithTimeout(shutdownCtx, componentTimeout) + err := component.Stop(componentCtx) + cancel() + + if errors.Is(err, context.DeadlineExceeded) { + logger.Warn("Component %s exceeded grace period, forcing termination", component.Name()) + } +} +``` + +### Pattern 5: Stdio Transport Alongside HTTP +**What:** When `--stdio` flag is present, run stdio transport in goroutine alongside HTTP server. Both share same MCP server instance. + +**When to use:** Need to support both HTTP and stdio MCP clients simultaneously. + +**Example:** +```go +// HTTP server always runs +go func() { + httpServer.ListenAndServe() +}() + +// Stdio transport optionally runs alongside +if stdioEnabled { + go func() { + server.ServeStdio(mcpServer) + }() +} + +// Both transports stop on context cancellation +<-ctx.Done() +``` + +### Anti-Patterns to Avoid +- **Separate HTTP servers on different ports:** Complicates deployment, firewall rules, and client configuration. Use single server with path-based routing. +- **Blocking Start() methods:** Components should start async work in goroutines and return quickly. Lifecycle manager doesn't wait for "ready" state, just successful initialization. +- **Ignoring shutdown errors:** Log shutdown failures but don't fail the shutdown process - other components still need to stop. +- **Mutex locks during shutdown:** Can cause deadlocks if component is already stopping. Use channels or atomic flags for shutdown coordination. + +## Don't Hand-Roll + +Problems that look simple but have existing solutions: + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| File watching with debounce | Custom fsnotify loop with timer | Existing IntegrationWatcher (internal/config/integration_watcher.go) | Already handles debouncing (500ms), reload errors, graceful stop. Tested in production. | +| Exponential backoff for retries | Manual time.Sleep loop | Simple doubling with max (or cenkalti/backoff if complex) | Integration retry needs jitter to avoid thundering herd. Keep it simple: start 1s, double each time, max 30s. | +| Signal handling boilerplate | Custom signal channel setup | signal.NotifyContext (Go 1.16+) | Creates cancellable context automatically, cleaner API | +| Component dependency ordering | Manual startup sequence | Existing lifecycle.Manager (internal/lifecycle/manager.go) | Topological sort for dependencies, rollback on failure, reverse-order shutdown. Don't recreate this. | +| CORS middleware | Custom header setting | Existing corsMiddleware (internal/apiserver/middleware.go) | Already handles preflight, all origins, proper headers for browser clients | +| MCP transport setup | Raw HTTP handler for MCP | mcp-go StreamableHTTPServer | Handles session management, request routing, error formatting per MCP spec | + +**Key insight:** Most "plumbing" already exists. This phase is primarily about composition - connecting existing pieces (lifecycle manager, integration manager, MCP server, REST server) into a unified startup/shutdown flow. + +## Common Pitfalls + +### Pitfall 1: SSE vs StreamableHTTP Confusion +**What goes wrong:** Context document specifies SSE transport, but MCP spec deprecated SSE as of 2025-03-26. Existing `mcp.go` command uses StreamableHTTP successfully. + +**Why it happens:** Context document was written before researching current MCP transport standards. + +**How to avoid:** Use StreamableHTTP transport (already in use). It's the current standard and provides better compatibility with MCP clients. + +**Warning signs:** If seeing "SSE Transport has been deprecated" in mcp-go documentation, you're on the wrong path. + +### Pitfall 2: Integration Manager Initialization Order +**What goes wrong:** Integration manager starts before MCP server exists, tries to register tools, crashes with nil pointer. + +**Why it happens:** Natural instinct is to start integrations early, but they need MCP server for tool registration. + +**How to avoid:** +1. Create MCP server first (but don't start HTTP listener yet) +2. Pass MCPToolRegistry to integration manager +3. Start integration manager (calls RegisterTools on each integration) +4. Then start HTTP server listening + +**Warning signs:** Panic on `MCPToolRegistry.RegisterTool()` with nil mcpServer. + +### Pitfall 3: Shutdown Timeout Too Short +**What goes wrong:** Components don't finish cleanup within timeout, lifecycle manager force-terminates, resources leak (open files, connections). + +**Why it happens:** Requirements specify 10s timeout, but some components (integrations, graph pipeline) may need longer. + +**How to avoid:** Test shutdown behavior under load. If timeout exceeded consistently, either: +- Optimize component shutdown (close connections faster) +- Increase timeout for specific components (lifecycle manager supports per-component timeout) + +**Warning signs:** Logs show "exceeded grace period, forcing termination" frequently. + +### Pitfall 4: Stdio and HTTP Mutual Exclusivity +**What goes wrong:** Implementing `--stdio` as mutually exclusive with HTTP means no HTTP server runs in stdio mode. + +**Why it happens:** Original MCP command has "http" or "stdio" transport choice. + +**How to avoid:** Requirements clarify: `--stdio` flag ADDS stdio alongside HTTP. HTTP always runs. Stdio is optional addition. + +**Warning signs:** Tests fail because no REST API available when using `--stdio`. + +### Pitfall 5: CORS Not Applied to MCP Endpoint +**What goes wrong:** Browser-based MCP clients can't connect to `/v1/mcp` endpoint due to CORS errors. + +**Why it happens:** MCP handler registered directly without going through CORS middleware. + +**How to avoid:** CORS middleware wraps entire router (already done in `apiserver.configureHTTPServer`). Ensure MCP handler is registered on the router BEFORE wrapping with CORS. + +**Warning signs:** Browser console shows "CORS policy: No 'Access-Control-Allow-Origin' header" for `/v1/mcp` requests. + +### Pitfall 6: Route Registration Order +**What goes wrong:** Static UI catch-all (`router.HandleFunc("/", ...)`) intercepts MCP requests. + +**Why it happens:** http.ServeMux matches routes in registration order when specificity is equal. + +**How to avoid:** Register routes from most specific to least specific: +1. Exact paths (`/health`, `/v1/mcp`) +2. API paths with prefixes (`/api/v1/*`) +3. Static UI catch-all (`/`) MUST BE LAST + +**Warning signs:** MCP endpoint returns UI HTML instead of handling MCP protocol. + +### Pitfall 7: MCP Server Lifecycle Component Implementation +**What goes wrong:** Treating MCP server as separate lifecycle component creates shutdown ordering problems. + +**Why it happens:** MCP server and REST server need to stop together, not in dependency order. + +**How to avoid:** MCP endpoint is just a handler on the same http.Server as REST. Don't create separate MCP lifecycle component. The apiserver component shuts down the http.Server which stops both REST and MCP. + +**Warning signs:** Need complex dependency declarations between "REST server" and "MCP server" components. + +## Code Examples + +Verified patterns from official sources: + +### StreamableHTTP Server Setup +```go +// Source: existing cmd/spectre/commands/mcp.go (lines 159-183) +// with stateless mode for compatibility +endpointPath := "/v1/mcp" + +streamableServer := server.NewStreamableHTTPServer( + mcpServer, + server.WithEndpointPath(endpointPath), + server.WithStateLess(true), // Stateless mode per requirements +) + +// Register on router +router.Handle(endpointPath, streamableServer) + +// StreamableHTTPServer handles: +// - GET /v1/mcp (SSE stream) +// - POST /v1/mcp (messages) +// - Session management (or stateless if WithStateLess(true)) +``` + +### Integration Manager with MCP Registry +```go +// Source: internal/integration/manager.go + internal/mcp/server.go patterns +// Create MCP server first +spectreServer, err := mcp.NewSpectreServerWithOptions(mcp.ServerOptions{ + SpectreURL: "http://localhost:8080", // Self-reference for in-process + Version: version, +}) + +// Create tool registry adapter +mcpRegistry := mcp.NewMCPToolRegistry(spectreServer.GetMCPServer()) + +// Create integration manager with registry +integrationMgr, err := integration.NewManagerWithMCPRegistry( + integration.ManagerConfig{ + ConfigPath: integrationsConfigPath, + MinIntegrationVersion: minIntegrationVersion, + }, + mcpRegistry, +) + +// Register with lifecycle (no dependencies) +manager.Register(integrationMgr) + +// When manager starts, it calls RegisterTools() on each integration +// which calls mcpRegistry.RegisterTool() which calls mcpServer.AddTool() +``` + +### Graceful Shutdown Flow +```go +// Source: cmd/spectre/commands/server.go (lines 526-549) + lifecycle manager +logger.Info("Starting Spectre v%s", Version) + +// Create lifecycle manager +manager := lifecycle.NewManager() +manager.SetShutdownTimeout(10 * time.Second) // Per requirements + +// Register components in dependency order +manager.Register(integrationMgr) // No dependencies +manager.Register(graphServiceComponent) // No dependencies +manager.Register(apiComponent, graphServiceComponent) // Depends on graph + +// Start all +ctx, cancel := context.WithCancel(context.Background()) +if err := manager.Start(ctx); err != nil { + logger.Error("Failed to start: %v", err) + os.Exit(1) +} + +logger.Info("Application started successfully") + +// Wait for shutdown signal +sigChan := make(chan os.Signal, 1) +signal.Notify(sigChan, syscall.SIGINT, syscall.SIGTERM) +<-sigChan + +logger.Info("Shutdown signal received, gracefully shutting down...") +cancel() + +// Graceful shutdown with timeout +shutdownCtx, shutdownCancel := context.WithTimeout(context.Background(), 10*time.Second) +defer shutdownCancel() + +if err := manager.Stop(shutdownCtx); err != nil { + logger.Error("Error during shutdown: %v", err) + os.Exit(1) +} + +logger.Info("Shutdown complete") +``` + +### Stdio Transport Alongside HTTP +```go +// Pattern for running stdio alongside HTTP server +// HTTP server runs as lifecycle component +httpServer := &http.Server{Addr: ":8080", Handler: handler} +go func() { + if err := httpServer.ListenAndServe(); err != nil && err != http.ErrServerClosed { + logger.Error("HTTP server error: %v", err) + } +}() + +// Stdio runs optionally in separate goroutine +if stdioEnabled { + logger.Info("Starting stdio MCP transport") + go func() { + // Blocks until client closes connection or context cancelled + if err := server.ServeStdio(mcpServer); err != nil { + logger.Error("Stdio transport error: %v", err) + } + }() +} + +// Both stop when context cancelled +<-ctx.Done() +shutdownCtx, cancel := context.WithTimeout(context.Background(), 5*time.Second) +defer cancel() +httpServer.Shutdown(shutdownCtx) +// Stdio stops automatically when context cancelled +``` + +### Config Hot-Reload with Debouncing +```go +// Source: internal/config/integration_watcher.go (already implemented) +// This is used by integration manager, no changes needed + +watcherConfig := config.IntegrationWatcherConfig{ + FilePath: integrationsConfigPath, + DebounceMillis: 500, // Per requirements +} + +watcher, err := config.NewIntegrationWatcher(watcherConfig, func(newConfig *config.IntegrationsFile) error { + // Callback: restart all integrations + logger.Info("Config reloaded, restarting integrations") + return integrationMgr.handleConfigReload(newConfig) +}) + +watcher.Start(ctx) // Starts watching in background +// Multiple file changes within 500ms coalesce to single reload +``` + +## State of the Art + +| Old Approach | Current Approach | When Changed | Impact | +|--------------|------------------|--------------|--------| +| SSE Transport for MCP | StreamableHTTP Transport | MCP spec 2025-03-26 | SSE deprecated, use StreamableHTTP.

From: Moritz Johner Date: Wed, 21 Jan 2026 20:19:45 +0100 Subject: [PATCH 114/342] feat(07-01): wire MCP tools to use TimelineService directly - Update SpectreServer to accept and store TimelineService in ServerOptions - Modify resource_timeline and cluster_health tools to accept TimelineService - Add WithClient constructors for backward compatibility with agent tools - Refactor MCP server initialization order: create API server first to get TimelineService - Update apiserver to create and expose TimelineService for sharing - Modify RegisterHandlers to accept TimelineService parameter instead of creating new instance - Add RegisterMCPEndpoint method to apiserver for late endpoint registration - Move integration manager initialization after MCP server creation - Verify tools no longer make HTTP self-calls for timeline operations Timeline tools now call shared service layer directly, eliminating HTTP overhead. REST handlers and MCP tools share same TimelineService instance. --- cmd/spectre/commands/server.go | 90 +++++++++++++++---------- internal/agent/tools/registry.go | 4 +- internal/api/handlers/register.go | 18 +---- internal/apiserver/routes.go | 1 + internal/apiserver/server.go | 34 ++++++++++ internal/mcp/server.go | 44 ++++++++---- internal/mcp/tools/cluster_health.go | 50 +++++++++++--- internal/mcp/tools/resource_timeline.go | 62 +++++++++++------ 8 files changed, 206 insertions(+), 97 deletions(-) diff --git a/cmd/spectre/commands/server.go b/cmd/spectre/commands/server.go index c046bfd..aa5c963 100644 --- a/cmd/spectre/commands/server.go +++ b/cmd/spectre/commands/server.go @@ -175,25 +175,13 @@ func runServer(cmd *cobra.Command, args []string) { manager := lifecycle.NewManager() logger.Info("Lifecycle manager created") -

/mcp, implementation uses /v1/mcp | -| 06-01 | Use --stdio flag instead of --transport=stdio | Simpler boolean vs enum | Requirement docs specify --transport=stdio, implementation uses --stdio | -| 06-01 | MCP server self-references localhost:8080 | Reuse existing tool implementations during transition | Phase 7 will eliminate HTTP overhead with direct service calls | -| 06-01 | StreamableHTTPServer with stateless mode | Client compatibility for session-less MCP clients | Each request includes full context | -| 06-02 | Phase 6 requirements fully validated | All 7 requirements verified working | Single-port deployment confirmed stable for production | -| 07-01 | Create API server before MCP server | TimelineService created by API server, needed by MCP tools | Enables direct service sharing, required init order change | -| 07-01 | Add RegisterMCPEndpoint for late registration | MCP endpoint must register after MCP server creation | Clean separation of API server construction and MCP registration | -| 07-01 | WithClient constructors for backward compatibility | Agent tools still use HTTP client pattern | Both patterns supported during transition | -| 07-02 | GraphService wraps existing analyzers | Facade pattern over PathDiscoverer, AnomalyDetector, Analyzer | Reuses proven logic, provides unified interface | -| 07-02 | Timeline integration deferred for detect_anomalies | TimelineService integration complex, uses HTTP for now | Keeps plan focused on graph operations | -| 07-02 | Dual constructors for MCP tools | NewTool(service) and NewToolWithClient(client) | Enables gradual migration, backward compatibility | -| 07-04 | MetadataService returns cache hit status | Service returns (response, cacheHit bool, error) tuple | Handler uses cacheHit for X-Cache header, cleaner than handler inspecting cache | -| 07-04 | useCache hardcoded to true in handler | Metadata changes infrequently, always prefer cache | Simplifies API surface, cache fallback handled by service | -| 07-04 | Service handles both efficient and fallback query paths | Check for MetadataQueryExecutor interface, fallback if unavailable | Centralizes query path selection in service layer | -| 07-05 | Delete HTTP client completely | HTTP client only used for self-calls in integrated server | Eliminates localhost HTTP overhead, cleaner service-only architecture | -| 07-05 | Disable standalone MCP and agent commands | Commands require HTTP to remote server, out of scope for Phase 7 | Breaking change acceptable, can refactor with gRPC/Connect in future | -| 07-05 | Build constraints on agent package | Agent depends on deleted HTTP client | Excludes agent from compilation, documents need for refactoring | -| 08-01 | Complete deletion approach for dead code | No TODO comments or deprecation stubs | Clean removal per Phase 8 context, deleted 14,676 lines (74 files) | -| 08-01 | Keep debug command even without subcommands | Future debug utilities may be added | Appears in Additional Help Topics, ready for future use | -| 08-03 | README MCP Integration section describes in-process architecture | Documentation must match actual Phase 6 implementation | Users understand MCP runs integrated on port 8080 at /v1/mcp | -| 08-03 | chart/README.md does not exist | Helm charts often document via values.yaml comments instead | No Helm chart README to update, values.yaml provides documentation | -| 08-02 | Remove MCP sidecar completely from Helm chart | After Phase 6, MCP runs in-process on port 8080 | Simplified deployment, lower resource usage, single-container architecture | -| 08-02 | Port consolidation: all HTTP traffic on port 8080 | Aligns with Phase 6 consolidated server | Simpler service definition, ingress routing, and firewall rules | -| 08-02 | Update test fixtures immediately | E2E tests in Phase 9 need correct architecture | Test fixtures ready, no follow-up work needed | -| 09-01 | E2E tests use /v1/mcp endpoint instead of /mcp | Aligns with Phase 6 decision for API versioning consistency | Test client sends requests to correct endpoint matching server implementation | -| 09-01 | E2E tests connect to port 8080 instead of 8082 | MCP now integrated on main server port after Phase 6-8 | Test infrastructure matches production consolidated architecture | -| 09-01 | Remove MCP Helm values from test deployment | MCP integrated by default, no separate config needed | Simplified test deployment configuration | -| 09-02 | Delete stdio transport tests completely | Phase 8 removed standalone 'spectre mcp' command | Test suite validates HTTP transport only, no obsolete subprocess tests | -| 09-02 | Orchestrator auto-fixed test imports from deleted mcp/client | Test files referenced package deleted

The most severe risks involve Go's stdlib plugin versioning constraints, template mining instability with variable-starting logs, race conditions in hot-reload without atomic updates, and state loss during progressive disclosure navigation. +Adding Logz.io integration and secret management introduces complexity across multiple dimensions: Elasticsearch DSL query limitations, multi-region configuration, rate limiting, scroll API lifecycle, fsnotify edge cases, and Kubernetes secret refresh mechanics. Critical pitfalls cluster around three areas: -**Key finding:** The stdlib `plugin` package has severe production limitations. HashiCorp's go-plugin (RPC-based) is the production-proven alternative, used by Terraform, Vault, Nomad, and Packer for 4+ years. +1. **Elasticsearch DSL query constraints** - Leading wildcards disabled, analyzed field limitations, scroll API expiration +2. **Secret rotation mechanics** - Kubernetes subPath breaks hot-reload, fsnotify misses atomic writes, race conditions during rotation +3. **Multi-region correctness** - Hard-coded endpoints, region-specific rate limits, credential scope confusion + +Many of these are subtle correctness issues that manifest in production under load, not during development. This research identifies early warning signs and prevention strategies for each. --- ## Critical Pitfalls -Mistakes that cause rewrites or major production issues. +Mistakes that cause rewrites, data loss, or security incidents. -### CRITICAL-1: Go Stdlib Plugin Versioning Hell +### Pitfall 1: Kubernetes Secret subPath Breaks Hot-Reload **What goes wrong:** -Using Go's stdlib `plugin` package creates brittle deployment where plugins crash with "plugin was built with a different version of package" errors. All plugins and the host must be built with: -- Exact same Go toolchain version -- Exact same dependency versions (including transitive deps) -- Exact same GOPATH -- Exact same build flags (`-trimpath`, `-buildmode=plugin`, etc.) +When secrets are mounted with `subPath`, Kubernetes updates the volume symlink but NOT the actual file bind-mounted into the container. Your fsnotify watcher detects no changes, application never reloads credentials, and you get authentication failures after secret rotation. **Why it happens:** -Go's plugin system loads `.so` files into the same process space. The runtime performs strict version checking on all shared packages. Even patch version differences in dependencies cause panics. +Kubernetes atomic writer uses symlinks for volume updates. With `subPath`, the symlink update happens at the mount point, not at the file level. The existing VictoriaLogs fsnotify watcher (`.planning/research/integration_watcher.go`) watches the file directly, which becomes stale with `subPath` mounts. **Consequences:** -- Plugin updates require rebuilding ALL plugins and host -- Cannot distribute third-party plugins (users can't build with your exact toolchain) -- Go version upgrades become coordination nightmares -- Production deployment requires lock-step versioning +- Secret rotation causes downtime (authentication fails) +- Monitoring alerts fire during rotation windows +- Manual pod restarts required to pick up new secrets +- Violates zero-downtime rotation requirement **Prevention:** -Use HashiCorp's `go-plugin` instead of stdlib `plugin`: -- RPC-based: plugins run as separate processes -- Protocol versioning: increment protocol version to invalidate incompatible plugins -- Cross-language: plugins don't need to be written in Go -- Production-proven: 4+ years in Terraform, Vault, Nomad, Packer -- Human-friendly errors when version mismatches occur +1. **DO NOT use `subPath` for secret mounts** - Mount entire secret volume, reference by path +2. Document in deployment YAML with explicit comment warning against subPath +3. Add integration test that verifies hot-reload with volume mount (not subPath) +4. Consider Secrets Store CSI Driver with Reloader for external vaults **Detection:** -Early warning signs: -- Investigating stdlib `plugin` package documentation -- Planning to distribute plugins to users -- Considering Go version upgrades with existing plugins - -**Phase mapping:** -Phase 1 (Plugin Architecture) must decide: stdlib `plugin` vs `go-plugin`.

Example: -- "cupsd shutdown succeeded" -- "irqbalance shutdown succeeded" - -These should map to template "{service} shutdown succeeded" but Drain creates separate templates because the first token differs. +Text editors (vim, VSCode, kubectl) use atomic writes: write temp file → rename to target. fsnotify watches the inode, which changes on rename. Watch is automatically removed, fsnotify stops receiving events, and config changes are silently ignored. **Why it happens:** -Drain uses a fixed-depth tree where the first few tokens determine which branch to follow. When constants appear AFTER variables, the tree structure breaks down. Log messages with different variable values at the start get routed to different branches, preventing template consolidation. +The existing `integration_watcher.go` handles this with Remove/Rename event re-watching (lines 140-148), BUT there's a 50ms sleep gap where the file might be written and you miss the event. Kubernetes Secret volume updates are atomic writes. VSCode triggers 5 events per save, creating race conditions in the debounce logic. **Consequences:** -- Template explosion: thousands of unique templates for the same pattern -- Inaccurate "new pattern" detection (false positives) -- High memory usage from redundant templates -- Degraded anomaly detection (signal lost in noise) -- Production accuracy drops below 90% on variable-starting logs +- Secret rotation silently fails (no reload triggered) +- Integration continues using expired credentials until health check fails +- Gap between rotation and detection creates security window +- Difficult to debug (no error, just missing events) **Prevention:** -1. **Pre-tokenize with masking:** Replace known variable patterns (IPs, UUIDs, numbers) BEFORE feeding to Drain -2. **Use Drain3 with masking:** The Drain3 implementation includes built-in masking for common patterns -3. **Consider XDrain:** Uses fixed-depth forest (not tree) with majority voting for better stability -4. **Sampling + validation:** Sample 10K logs from each namespace, validate template count is reasonable (<1000 for typical app logs) -5. **Fallback detection:** If template count exceeds threshold, flag namespace for manual review +1. **Verify existing re-watch logic handles Kubernetes volume updates** - Test with actual Secret mount +2. **Increase re-watch delay from 50ms to 200ms** for Kubernetes atomic writes (slower than editor saves) +3. **Watch parent directory, not file** - Recommended by fsnotify docs (avoids inode change problem) +4. **Add file existence check after re-watch** - Verify file exists before continuing +5. **Log all watch removals and re-additions** - Make missing events visible **Detection:** -Warning signs: -- Template count growing unbounded (monitor templates-per-1000-logs metric) -- Most templates have only 1-5 instances (indicates over-fragmentation) -- "New pattern" alerts firing constantly -- High cardinality in first token position during analysis - -**Phase mapping:** -- Phase 2 (Template Mining): Algorithm selection must account for variable-starting logs -- Phase 3 (VictoriaLogs Integration): Need sampling and validation before production use -- Phase 4 (Progressive Disclosure): Template count explosion breaks aggregated view +- Warning sign: Watcher logs show Remove/Rename events but no subsequent reload +- Warning sign: Time gap between secret update and reload > 500ms +- Test: Simulate atomic write (write temp → rename), verify fsnotify event within 200ms -**Confidence:** HIGH (verified by academic papers, Drain3 documentation, production stability reports) +**References:** +- [fsnotify Issue #372: Robustly watching a single file](https://github.com/fsnotify/fsnotify/issues/372) +- [Building a cross-platform File Watcher in Go](https://dev.to/asoseil/building-a-cross-platform-file-watcher-in-go-what-i-learned-from-scratch-1dbj) -**Sources:** -- [Investigating and Improving Log Parsing in Practice](https://yanmeng.github.io/papers/FSE221.pdf) -- [Drain3: Robust streaming log template miner](https://github.com/logpai/Drain3) -- [XDrain: Effective log parsing with fixed-depth forest](https://www.sciencedirect.com/science/article/abs/pii/S0950584924001514) -- [Tools and Benchmarks for Automated Log Parsing](https://arxiv.org/pdf/1811.03509) +**Which phase:** +Phase 2 (Logz.io API Client) - Critical for secret hot-reload, blocks production deployment --- -### CRITICAL-3: Race Conditions in Config Hot-Reload Without Atomic Swap +### Pitfall 3: Leading Wildcard Queries Disabled by Logz.io **What goes wrong:** -Naive hot-reload implementations use `sync.RWMutex` to guard a config struct, then modify it in place during reload. This creates race conditions: -1. Goroutine A reads `config.VictoriaLogsURL` -2. Reload happens, sets `config.VictoriaLogsURL = newURL` -3. Goroutine A reads `config.VictoriaLogsAPIKey` (now inconsistent with URL) -4. Request goes to newURL with oldAPIKey → authentication failure - -Even with RWMutex, readers can observe partially-updated config state. +Logz.io API enforces `allow_leading_wildcard: false` on query_string queries. User tries query like `*-service` to find all services, gets error. This is NOT documented clearly in their API docs, only buried in their UI help. **Why it happens:** -RWMutex only prevents concurrent reads/writes, not partial reads across field updates. If reload updates multiple fields, readers may see: -- Some old fields, some new fields (torn reads) -- Config in invalid intermediate state (e.g., URL points to prod but timeout is still dev value) +Leading wildcards require scanning every term in the index (extremely expensive). Logz.io disables this for performance/cost reasons. Standard Elasticsearch clients default to allowing it, creating mismatch with Logz.io API expectations. **Consequences:** -- Intermittent request failures during config reload -- Authentication errors with mismatched credentials -- Timeouts with wrong timeout values -- Silent data corruption if config fields are interdependent -- Difficult to reproduce (timing-sensitive) +- MCP tool queries fail with cryptic errors +- Users familiar with Elasticsearch expect this to work +- Workarounds (use filters, analyzed fields) are non-obvious +- Degrades user experience of AI assistant tools **Prevention:** -Use **atomic pointer swap pattern**: - -```go -type Config struct { - // config fields -} - -type HotReloadable struct { - config atomic.Value // stores *Config -} - -func (h *HotReloadable) Get() *Config { - return h.config.Load().(*Config) -} - -func (h *HotReloadable) Reload(newConfig *Config) { - // Validate newConfig first - if err := newConfig.Validate(); err != nil { - log.Warn("Config validation failed, keeping old config", "error", err) - return - } - - // Single atomic swap - readers see old OR new, never partial - h.config.Store(newConfig) -} -``` - -Additional safeguards: -1. **Validate before swap:** Never store invalid config -2. **Deep copy on read if mutating:** Prevent readers from mutating shared config -3. **Version numbering:** Include config version for debugging -4. **Rollback on partial failure:** If plugin initialization fails with new config, revert to old +1. **Document leading wildcard limitation prominently** in MCP tool descriptions +2. **Validate queries before sending to API** - Reject leading wildcards with helpful error +3. **Suggest alternatives in error message** - "Use field filters instead of leading wildcards" +4. **Pre-query field mapping check** - Identify analyzed fields that support tokenized search +5. **Add query builder helper** that constructs valid Logz.io queries **Detection:** -Warning signs: -- Planning to use `sync.RWMutex` with multi-field config struct -- Reload logic updates fields one-by-one -- No validation before applying new config -- No rollback mechanism for failed reloads +- Warning sign: API returns 400 errors on wildcard queries +- Test: Attempt query with leading wildcard, verify helpful error message + +**References:** +- [Logz.io Wildcard Searches](https://docs.logz.io/kibana/wildcards/) +- [Logz.io Search Logs API](https://api-docs.logz.io/docs/logz/search/) +- [Elasticsearch Query DSL Guide](https://logz.io/blog/elasticsearch-queries/) + +**Which phase:** +Phase 3 (MCP Tool Implementation) - Query validation layer before API client calls + +--- + +### Pitfall 4: Scroll API Context Expiration After 20 Minutes + +**What goes wrong:** +Logz.io scroll API contexts expire after 20 minutes. If MCP tool takes >20min to process results (e.g., pattern mining large dataset), scroll_id becomes invalid. Subsequent scroll requests fail with "expired scroll ID" error, and you lose your pagination state. + +**Why it happens:** +Scroll contexts hold cluster resources (search state, results cache). 20-minute timeout is aggressive compared to Elasticsearch default (1 minute, but adjustable). The project context mentions this limit but doesn't explain implications for long-running operations. + +**Consequences:** +- Pattern mining tool fails mid-operation on large namespaces +- Partial results without clear indication of incompleteness +- User retries query, hits rate limit, degrades service +- Cannot paginate through large result sets (>10,000 logs) + +**Prevention:** +1. **Use scroll API only for result sets needing >1,000 logs** (Logz.io aggregation limit) +2. **Set aggressive internal timeout (15 min)** - Leave 5min buffer before API expiration +3. **Implement checkpoint/resume** - Save last processed position, allow restart +4. **Consider Point-in-Time API** if Logz.io supports it (newer alternative to scroll) +5. **Stream results to caller incrementally** - Don't buffer entire dataset in memory +6. **Clear scroll context after use** - Free resources promptly -**Phase mapping:** -Phase 1 (Config Hot-Reload) must use atomic swap from day 1.

Template miners trained on old logs fail to recognize new patterns, causing: -- Template explosion as drift occurs -- Accuracy degradation from 90%+ to <70% -- False "new pattern" alerts (actually old pattern with new format) -- Stale templates never merged with similar new ones +Logz.io uses different API endpoints per region (us-east-1, eu-central-1, ap-southeast-2, etc.). If you hard-code the endpoint URL in config or default to US region, users in other regions get authentication failures or routing errors. **Why it happens:** -Initial clustering creates boundaries. New logs that are semantically similar but syntactically different (e.g., "ERROR: connection timeout" becomes "ERROR connection timeout" after log library upgrade) land in separate clusters. Without rebalancing, these never merge. +Multi-region architecture is common in observability SaaS, but not obvious to new integrators. The project context mentions "multi-region: different API endpoints" but doesn't specify how to determine correct endpoint. Users expect a single API domain. **Consequences:** -- Production accuracy drops from 90% to <70% after 30-60 days -- Template count grows unbounded (memory leak) -- "New pattern" detection becomes useless (too many false positives) -- Pattern comparison vs previous window breaks (formats don't match) -- Requires manual intervention or service restart to fix +- Authentication fails for non-US users (wrong region, token not valid) +- Higher latency for users far from hard-coded region +- Data sovereignty violations (EU data routed through US) +- Support burden ("integration doesn't work for me") **Prevention:** -1. **Periodic rebalancing:** Drain3's HELP implementation includes iterative rebalancing that merges similar clusters -2. **Similarity threshold tuning:** Monitor template count growth and adjust similarity threshold if growing too fast -3. **Template TTL:** Expire templates not seen in N days (configurable, default 30d) -4. **Ensemble adaptation:** Use directed lifelong learning (maintain ensemble of parsers, add new one when drift detected) -5. **Drift detection metrics:** Track templates-per-1000-logs ratio, alert if ratio exceeds threshold +1. **Require region as explicit config parameter** - No defaults, force user to specify +2. **Validate region against known list** - Reject invalid regions early with helpful message +3. **Construct endpoint URL from region** - `https://api-{region}.logz.io` pattern +4. **Document region discovery process** - Link to Logz.io docs showing how to find your region +5. **Add region to MCP tool descriptions** - Make it visible which instance serves which region **Detection:** -Warning signs: -- Template count growing linearly over time (not plateau) -- Most templates created in last 7 days (indicates old templates not being reused) -- Monitoring Population Stability Index (PSI) shows distribution shift -- "New pattern" alerts correlate with service deployments (expected) AND with time (drift) +- Warning sign: Authentication works in staging but fails in production (different regions) +- Warning sign: High latency in API calls (cross-region routing) +- Test: Configure integration for each known region, verify correct endpoint construction -**Phase mapping:** -- Phase 2 (Template Mining): Must include rebalancing mechanism from start -- Phase 3 (Monitoring): Track drift metrics (template count, PSI, creation timestamps) -- Phase 4 (Production hardening): Add template TTL and ensemble adaptation +**References:** +- [Azure APIM Multi-Region Concepts](https://github.com/MicrosoftDocs/azure-docs/blob/main/includes/api-management-multi-region-concepts.md) +- [Multi-Region API Gateway Deployment Guide](https://www.eyer.ai/blog/multi-region-api-gateway-deployment-guide/) -**Confidence:** HIGH (verified by academic research, production log analysis systems, Drain3 documentation) +**Which phase:** +Phase 1 (Planning & Research) - Architecture decision before implementation starts -**Sources:** -- [Adaptive Log Anomaly Detection through Drift Characterization](https://openreview.net/pdf?id=6QXrawkcrX) -- [HELP: Hierarchical Embeddings-based Log Parsing](https://www.themoonlight.io/en/review/help-hierarchical-embeddings-based-log-parsing) -- [System Log Parsing with LLMs: A Review](https://arxiv.org/pdf/2504.04877) +--- + +### Pitfall 6: Secret Value Logging During Debug + +**What goes wrong:** +During development/debugging, developers add log statements that inadvertently log secret values (API tokens, connection strings with passwords).

Plugin built against 2025-06-18 fails to connect to client supporting only 2025-03-26. Instead of graceful degradation, connection fails silently or with cryptic error. +Logz.io enforces 100 concurrent requests per account. Without exponential backoff, multiple MCP tools hitting rate limit will retry immediately, amplifying the problem. Fixed-delay retries create thundering herd when rate limit resets. **Why it happens:** -MCP protocol version negotiation happens during initialization. If server declares only newer protocol version and client supports only older version, they cannot agree on common version. Without explicit handling, this manifests as connection timeout or protocol error. +Rate limiting is account-wide, not per-instance. Multiple users running Claude Code simultaneously share the same rate limit. Naive retry logic uses fixed delays or immediate retries. HTTP 429 responses don't include Retry-After header (not documented). + +**Consequences:** +- Request storms during rate limit periods +- Degraded service for all users sharing account +- MCP tools time out waiting for responses +- Support tickets for "integration randomly fails" **Prevention:** -1. **Multi-version support:** Server declares all supported protocol versions: `["2025-11-25", "2025-06-18", "2025-03-26"]` -2. **Feature detection, not version checking:** Check for specific capabilities (e.g., async tasks) rather than version string -3. **Graceful fallback:** If client only supports old version, use subset of features available in that version -4. **Clear error messages:** If no common version, return human-friendly error: "Server requires MCP 2025-06-18+, client supports 2025-03-26" -5. **Version in health endpoint:** Expose supported protocol versions in status endpoint for debugging +1. **Implement exponential backoff with jitter** - Start at 1s, double each retry, max 32s +2. **Track rate limit globally per instance** - Share state across tool invocations +3. **Fail fast after 3 retries** - Return clear error to user, don't hang +4. **Add rate limit metrics** - Expose `logzio_rate_limit_hits_total` counter +5. **Document concurrent request limit** in integration configuration +6. **Consider request queuing** - Serialize requests to stay under limit **Detection:** -- Planning single protocol version support -- Hard-coding protocol version checks -- No fallback for missing features -- Connection errors without version information - -**Phase mapping:** -Phase 1 (Plugin Architecture): Design plugin interface to support multiple MCP protocol versions. +- Warning sign: Bursts of 429 errors in logs +- Warning sign: Request latency spikes during high usage +- Test: Send 101 concurrent requests, verify graceful handling -**Confidence:** MEDIUM (MCP spec documentation, production deployment reports) +**References:** +- [Logz.io Metrics Throttling](https://docs.logz.io/docs/user-guide/infrastructure-monitoring/metric-throttling/) +- [API Rate Limiting Strategies](https://nhonvo.github.io/posts/2025-09-07-api-rate-limiting-and-throttling-strategies/) +- [Exponential Backoff Strategy](https://substack.thewebscraping.club/p/rate-limit-scraping-exponential-backoff) -**Sources:** -- [MCP Versioning Specification](https://modelcontextprotocol.io/specification/versioning) -- [MCP 2025-11-25 Release](https://blog.modelcontextprotocol.io/posts/2025-11-25-first-mcp-anniversary/) -- [MCP Best Practices](https://modelcontextprotocol.info/docs/best-practices/) +**Which phase:** +Phase 2 (Logz.io API Client) - HTTP client configuration with retry middleware --- -### MODERATE-2: Cross-Client Template Inconsistency Without Canonical Storage +### Pitfall 8: Result Limit Confusion (1,000 vs 10,000) **What goes wrong:** -Two clients (IDE plugin, CLI) mine templates independently. Same log message gets template ID "a7b3c4" in IDE but "f9e2d1" in CLI. User asks "show me instances of template a7b3c4" in CLI → no results (CLI doesn't have that ID). +Logz.io has TWO result limits: 1,000 for aggregated results, 10,000 for non-aggregated. MCP tool tries to fetch 5,000 log messages (non-aggregated), expects it to work based on 10,000 limit, but uses aggregation query by accident and gets 1,000-row limit error. **Why it happens:** -Template mining is sensitive to: -- Processing order (first-seen logs influence tree structure) -- Sampling (if sampling differently, see different representative logs) -- Algorithm parameters (similarity threshold, max depth) -- Initialization state (empty tree vs pre-populated) +The distinction between aggregated vs non-aggregated is subtle. Aggregation happens implicitly when grouping by fields. Project context mentions both limits but doesn't explain which queries use which.

Test crashes take down entire test suite. Flaky tests due to global state pollution between plugin loads. +Elasticsearch analyzed fields (like `message`) are tokenized for full-text search. You cannot sort or aggregate on them. MCP tool tries `"sort": [{"message": "asc"}]` and gets cryptic error about "fielddata disabled on text fields." **Why it happens:** -Stdlib `plugin.Open()` loads `.so` into current process. Cannot unload. Global variables in plugin persist across test cases. Panic in plugin panics test runner. +Field mapping determines whether field is analyzed (full-text) or keyword (exact match). Logz.io auto-maps many fields, but behavior may differ from self-hosted Elasticsearch. Sorting/aggregation requires keyword fields.

High-volume namespaces emit thousands of logs per second. UI becomes unusable, VictoriaLogs CPU spikes, websocket connections timeout. +On macOS, fsnotify uses kqueue, which requires one file descriptor per watched file. If you watch many integration config files (or watch a directory with many files), you hit the OS limit (default 256) and get "too many open files" error. **Why it happens:** -VictoriaLogs documentation explicitly warns: "It isn't recommended setting too low value for refresh_interval query arg, since this may increase load on VictoriaLogs without measurable benefits." Live tailing is optimized for human inspection (up to 1K logs/sec), not machine processing. +macOS kqueue is more resource-intensive than Linux inotify. The existing integration watcher watches a single file, but if deployment pattern involves watching multiple config files (one per integration instance), the problem scales. This is a platform-specific behavior. **Consequences:** -- VictoriaLogs CPU usage spikes -- UI freezes trying to render thousands of log lines -- Websocket connections saturate network -- False impression that VictoriaLogs is slow (actually client abuse) -- User cannot read logs scrolling at 10K/sec anyway +- Watcher fails to start on macOS (development machines) +- Error is cryptic ("too many open files" doesn't mention fsnotify) +- Works fine on Linux (CI/production), fails on developer laptops +- Blocks local testing of multi-instance scenarios **Prevention:** -1. **Minimum refresh interval:** 1 second minimum, recommend 5 seconds -2. **Rate limiting in UI:** If logs exceed 1K/sec, show warning and suggest adding filters -3. **Auto-pause on high rate:** Pause streaming if rate exceeds threshold, require user action to resume -4. **Sampling for preview:** Show sampled logs (1 in N) during high-volume periods -5. **Filter-first UX:** Require namespace + severity filter before enabling live tail +1. **Watch parent directory, not individual files** - Single file descriptor for entire directory +2. **Filter events by filename** - Ignore irrelevant files in directory +3. **Document macOS ulimit requirement** - `ulimit -n 4096` in setup docs +4. **Add startup check** - Verify file descriptor limit is sufficient +5. **Log clear error** - "fsnotify failed: increase file descriptor limit (ulimit -n 4096)" **Detection:** -- Planning live tail feature -- No refresh_interval limits in UI -- No rate detection or warnings -- Testing with low-volume logs only +- Warning sign: "too many open files" error during watcher startup +- Warning sign: Watcher works on Linux CI, fails on macOS laptops +- Test: Create 300 watched files, verify watcher starts successfully (or errors helpfully) -**Phase mapping:** -Phase 3 (VictoriaLogs Integration): Live tail is nice-to-have, defer to later phase. -Phase 4 (Progressive Disclosure): Focus on aggregated view first, raw logs last. +**References:** +- [fsnotify GitHub README](https://github.com/fsnotify/fsnotify) +- [Building a cross-platform File Watcher in Go](https://dev.to/asoseil/building-a-cross-platform-file-watcher-in-go-what-i-learned-from-scratch-1dbj) -**Confidence:** HIGH (VictoriaLogs official documentation) - -**Sources:** -- [VictoriaLogs Querying Documentation](https://docs.victoriametrics.com/victorialogs/querying/) -- [VictoriaLogs FAQ](https://docs.victoriametrics.com/victorialogs/faq/) +**Which phase:** +Phase 2 (Logz.io API Client) - File watching infrastructure setup --- -### MODERATE-5: UI State Loss During Progressive Disclosure Navigation +### Pitfall 11: Dual-Phase Secret Rotation Not Implemented **What goes wrong:** -User is in "Aggregated View" for namespace "api-gateway", drills into a specific template, clicks browser back button → loses all state, returns to global overview. Expected: return to namespace "api-gateway" aggregated view. +Old secret is invalidated immediately when new secret is generated. During rotation, there's a window where application has old secret cached but it's already invalid. Requests fail with 401 errors until hot-reload completes. **Why it happens:** -Progressive disclosure creates three view levels (global → aggregated → full logs). If state is component-local (React useState), navigation resets it. Browser back/forward buttons don't restore component state. +Simple rotation (generate new → invalidate old) assumes instant propagation. File-based hot-reload takes time (fsnotify event → reload → HTTP client update). Kubernetes kubelet syncs volumes every 60s by default. Secret provider may not support overlapping active versions. **Consequences:** -- Poor UX: users must manually navigate back through levels -- Lost context: selected filters, time ranges, templates -- Frustration: "I was just looking at that namespace, now I have to find it again" -- Users avoid drilling down (defeats purpose of progressive disclosure) +- Downtime during secret rotation (seconds to minutes) +- 401 errors visible to users during rotation window +- Rotation becomes risky, teams avoid doing it regularly +- Security posture degrades (stale secrets stay active) **Prevention:** -1. **URL state:** Encode state in URL query params: `?view=aggregated&namespace=api-gateway&template=a7b3c4` -2. **React Router with state:** Use `location.state` to pass context between routes -3. **Global state manager:** Zustand or Context API for cross-component state -4. **Session storage fallback:** Persist state to sessionStorage as backup -5. **Breadcrumb navigation:** Show "Global > api-gateway > template-a7b3c4" with clickable links - -Example URL structure: -``` -/logs # Global overview -/logs?ns=api-gateway # Aggregated view for namespace -/logs?ns=api-gateway&tpl=a7b3c4 # Full logs for template -``` +1. **Use dual-phase rotation** - Generate new, wait for propagation, invalidate old +2. **Support multiple active tokens** - Application accepts both old and new during transition +3. **Implement grace period** - Keep old secret valid for 5 minutes after new one deployed +4. **Monitor rotation health** - Alert if 401 errors spike during rotation +5. **Document rotation procedure** - Step-by-step with verification checkpoints +6. **Test rotation in staging** - Verify zero-downtime before production **Detection:** -- Planning multi-level navigation without URL state -- Using component-local state for navigation context -- No breadcrumb UI -- Browser back button not tested - -**Phase mapping:** -Phase 4 (Progressive Disclosure UI): URL-based state from day 1, hard to retrofit. +- Warning sign: 401 errors during known rotation windows +- Test: Rotate secret while load testing, verify no 401s -**Confidence:** MEDIUM (SPA best practices, React state management guidance) +**References:** +- [Zero Downtime Secrets Rotation: 10-Step Guide](https://www.doppler.com/blog/10-step-secrets-rotation-guide) +- [AWS: Rotate database credentials without restarting containers](https://docs.aws.amazon.com/prescriptive-guidance/latest/patterns/rotate-database-credentials-without-restarting-containers.html) +- [Secrets rotation strategies for long-lived services](https://technori.com/news/secrets-rotation-long-lived-services/) -**Sources:** -- [State is hard: why SPAs will persist](https://nolanlawson.com/2022/05/29/state-is-hard-why-spas-will-persist/) -- [React State Management 2025](https://www.developerway.com/posts/react-state-management-2025) -- [State Management in SPAs](https://blog.pixelfreestudio.com/state-management-in-single-page-applications-spas/) +**Which phase:** +Phase 2 (Logz.io API Client) - Client initialization and credential refresh logic --- ## Minor Pitfalls -Mistakes that cause annoyance but are fixable. +Mistakes that cause inconvenience but are easily fixable. -### MINOR-1: No Config Validation Before Hot-Reload +### Pitfall 12: Time Range Default Confusion (Seconds vs Milliseconds) **What goes wrong:** -Hot-reload picks up new config file with typo in VictoriaLogs URL: `http://victorialogs:8428/selec` (missing 't' in 'select').

Their API is Elasticsearch DSL over HTTP with custom auth header. Use stdlib HTTP client with custom `RoundTripper` for auth injection, leverage `go-elasticsearch` types for response parsing only (not transport). -The native `plugin` package has critical limitations that make it unsuitable for this use case: -- **Platform-locked**: Only works on Linux, FreeBSD, and macOS (no Windows support) -- **Build coupling**: Plugins and host must be built with identical toolchain versions, build tags, and flags -- **No unloading**: Once loaded, plugins cannot be unloaded (memory leak risk) -- **Race detector incompatibility**: Poor support for race condition detection +### Elasticsearch DSL Query Building -HashiCorp go-plugin solves these problems through RPC-based isolation: -- **Cross-platform**: Works everywhere Go runs via standard net/rpc or gRPC -- **Process isolation**: Plugin crashes don't crash the host MCP server -- **Independent builds**: Plugins can be compiled separately and upgraded independently -- **Security**: Plugins only access explicitly exposed interfaces, not entire process memory -- **Battle-tested**: Used by Terraform, Vault, Nomad, Packer (production-proven on millions of machines) +| Technology | Version | Purpose | Why | +|------------|---------|---------|-----| +| `github.com/sdqri/effdsl/v2` | v2.2.0 | Type-safe Elasticsearch query builder | Actively maintained (last release Sept 2024), supports go-elasticsearch v8, provides functional API for programmatic query construction, MIT license | -**Trade-off**: Slightly lower performance vs native plugins (RPC overhead), but negligible for observability integrations where network I/O dominates. +**Alternatives Considered:** +- `aquasecurity/esquery`: **REJECTED** - Only supports go-elasticsearch v7, stale (last release March 2021), marked as "early release" with API instability warnings +- `olivere/elastic`: **REJECTED** - Officially deprecated, author abandoned v8+ support +- Raw `map[string]interface{}`: **REJECTED** - Error-prone for complex queries, no compile-time safety, maintenance burden -**Installation:** -```bash -go get github.com/hashicorp/go-plugin@v1.7.0 -``` +### Secret Management -**Sources:** -- [HashiCorp go-plugin on Go Packages](https://pkg.go.dev/github.com/hashicorp/go-plugin) (HIGH confidence) -- [Building Dynamic Applications with Go Plugins](https://leapcell.io/blog/building-dynamic-and-extensible-applications-with-go-plugins) (MEDIUM confidence) -- [Native plugin limitations](https://pkg.go.dev/plugin) (HIGH confidence - official docs) +| Technology | Version | Purpose | Why | +|------------|---------|---------|-----| +| `github.com/fsnotify/fsnotify` | v1.9.0 | File system change notifications | Already in `go.mod`, proven in production at `internal/config/integration_watcher.go`, cross-platform, handles K8s Secret atomic writes (RENAME events) | +| `os.ReadFile` (stdlib) | Go 1.24.4 | Read secret file contents | Standard library, sufficient for reading mounted Secret files | + +**Rationale:** Kubernetes mounts Secrets as files with automatic updates via atomic writes (RENAME events).

The integration follows the proven VictoriaLogs plugin pattern but introduces three architectural extensions: multi-region API client, file-based secret hot-reload via fsnotify, and Elasticsearch DSL query building. Research confirms feasibility with clear implementation path and identified risks. + +**Core technology decision:** Use stdlib `net/http` with `elastic/go-elasticsearch` types + `effdsl/v2` query builder. Logz.io has no official Go SDK—build custom HTTP client following Elasticsearch compatibility patterns. Extend existing fsnotify-based config watcher to support Kubernetes Secret file mounts with atomic write handling. + +**Critical findings:** Logz.io's Patterns Engine (pre-computed log clustering) has unclear API exposure—research recommends investigating pattern metadata fields during Phase 1, with fallback to VictoriaLogs-style Drain mining if unavailable. Secret management requires careful fsnotify handling due to Kubernetes atomic symlink rotation (subPath volumes break hot-reload). Multi-region support is table stakes (5 regional endpoints with different URLs). + +**Key risk:** Kubernetes Secret subPath incompatibility with hot-reload. This is a critical pitfall that blocks zero-downtime credential rotation. Prevention requires volume-level mounts (not file-level subPath) and re-establishing fsnotify watches after atomic write events. + +**Roadmap readiness:** Clear 5-phase structure emerges from research. Phase 1-2 (client foundation + secret management) are low-risk with proven patterns. Phase 3-4 (pattern mining + MCP tools) need targeted research flags for Pattern API verification and scroll lifecycle management. Overall confidence: HIGH for delivery, MEDIUM for timeline estimation (patterns uncertainty). + +## Key Findings + +### Recommended Stack + +**HTTP Client Layer:** +- `net/http` (stdlib) - Custom HTTP client with regional endpoint mapping, sufficient for bearer auth +- `elastic/go-elasticsearch` v8.18.0 or v9.2.1 -

Read API token from Kubernetes Secret volume mount +- File-based pattern: `/var/run/secrets/logzio/api-token` (no environment variables) + +**Regional Endpoints:** +| Region | API Base URL | +|--------|--------------| +| US | `https://api.logz.io` | +| EU | `https://api-eu.logz.io` | +| UK | `https://api-uk.logz.io` | +| AU | `https://api-au.logz.io` | +| CA | `https://api-ca.logz.io` | + +**Why this stack:** +- Consistency: Mirrors VictoriaLogs HTTP client pattern (custom transport for auth injection) +- Type safety: effdsl prevents Elasticsearch DSL syntax errors at compile time +- Hot-reload: fsnotify proven in production for config watching, extends to secret files +- Kubernetes-native: Volume-mounted secrets work with any secret backend (Vault, AWS, manual) + +**Rejected alternatives:** +- `olivere/elastic` - Officially deprecated (author abandoned v8+ support) +- `aquasecurity/esquery` - Stale (last release March 2021), only supports go-elasticsearch v7 +- Environment variables for secrets - No hot-reload support (requires pod restart) +- Raw JSON query strings - Error-prone, no compile-time validation + +### Expected Features + +**Table Stakes (VictoriaLogs Parity):** + +1. **Overview Tool** - Namespace-level severity summary + - API: `/v1/search` with terms aggregation on `kubernetes.namespace` + - Parallel queries: total, errors, warnings (same pattern as VictoriaLogs) + - Confidence: HIGH - Standard Elasticsearch aggregations, well-documented + +2. **Logs Tool** - Raw log retrieval with filters + - Filters: namespace, pod, container, severity, time range + - Result limits: 1,000 per page (aggregated), 10,000 total (non-aggregated) + - Scroll API available for pagination beyond limits + - Confidence: HIGH - Core Search API functionality + +3. **Patterns Tool** - Log template clustering + - Logz.io has built-in Patterns Engine (pre-computed during ingestion) + - **CRITICAL UNCERTAINTY:** Pattern metadata API exposure unclear + - Fallback: Reuse VictoriaLogs Drain algorithm + TemplateStore if API unavailable + - Confidence: LOW for native patterns, HIGH for fallback mining + +**Differentiators (Logz.io-Specific):** + +1. **Pre-Computed Patterns** - No CPU-intensive mining required if API exposes pattern metadata +2. **Scroll API** - Unlimited pagination vs VictoriaLogs 500-log hard limit +3. **Advanced Aggregations** - Cardinality, percentiles, stats (richer than LogsQL) +4. **Multi-Region Support** - Geographic data locality, compliance requirements + +**Anti-Features (Deliberately Excluded):** + +1. **Custom pattern mining when native patterns available** - Duplicates built-in functionality +2. **Sub-account management** - Out of scope for read-only observability tool +3. **Real-time alerting** - Logz.io Alert API handles this, Spectre is query-driven +4. **Leading wildcard searches** - Explicitly prohibited by Logz.io API +5. **Multi-account parallel querying** - Scroll API limited to single account + +**Secret Management Requirements:** + +- API token storage (sensitive, no expiration, manual rotation) +- Region configuration (5 options, affects endpoint URL) +- Connection validation (test query during setup) +- Rate limit handling (100 concurrent requests per account) +- Hot-reload support (zero-downtime credential rotation) +- Encryption at rest (Kubernetes-level, not application-level) + +### Architecture Approach + +**Component Structure:** + +``` +LogzioIntegration (internal/integration/logzio/logzio.go) +├── RegionalClient (client.go) -

Kubernetes Secret subPath Breaks Hot-Reload** (CRITICAL) +- **Problem:** subPath mounts bypass Kubernetes atomic writer, fsnotify never detects updates +- **Impact:** Secret rotation causes downtime, authentication failures, manual pod restarts required +- **Prevention:** Volume-level mounts only (not subPath), document explicitly in deployment YAML +- **Phase:** Phase 2 (Secret Management) - Must validate before MCP tools + +**2. Atomic Editor Saves Cause fsnotify Watch Loss** (CRITICAL) +- **Problem:** Kubernetes Secret updates use rename → fsnotify watch on inode breaks → events missed +- **Impact:** Silent secret reload failures, security window between rotation and detection +- **Prevention:** Re-establish watch after Remove/Rename events, increase debounce to 200ms, watch parent directory +- **Phase:** Phase 2 (Secret Management) - Core hot-reload reliability + +**3. Leading Wildcard Queries Disabled by Logz.io** (MODERATE) +- **Problem:** API enforces `allow_leading_wildcard: false`, queries like `*-service` fail +- **Impact:** User-facing errors, degrades MCP tool experience +- **Prevention:** Query validation layer, reject leading wildcards with helpful error message +- **Phase:** Phase 3 (MCP Tools) - Query construction validation + +**4. Scroll API Context Expiration After 20 Minutes** (MODERATE) +- **Problem:** Long-running pattern mining operations lose scroll context mid-operation +- **Impact:** Incomplete results, user retries hit rate limit +- **Prevention:** 15-minute internal timeout, checkpoint/resume for large datasets, stream results incrementally +- **Phase:** Phase 3 (MCP Tools) - Pattern mining implementation + +**5. Secret Value Logging During Debug** (CRITICAL - SECURITY) +- **Problem:** API tokens logged in error messages, config dumps, HTTP request logs +- **Impact:** Credential leakage to logs, compliance violation, incident response burden +- **Prevention:** Struct tags for secret fields, redact tokens in String() methods, sanitize HTTP errors +- **Phase:** Phase 2 (Secret Management) - Establish logging patterns before MCP tools + +**Additional Moderate Pitfalls:** + +- **Rate limit handling without exponential backoff** - 100 concurrent requests per account, need jitter retry +- **Result limit confusion (1K vs 10K)** - Aggregated queries have 1K limit, non-aggregated 10K +- **Analyzed field sorting/aggregation failure** - Text fields don't support sorting, need `.keyword` suffix +- **Multi-region endpoint hard-coding** - Must construct URL from region config, no defaults +- **Dual-phase rotation not implemented** - Brief window where old token invalid, new not loaded yet + +**Early Warning Signs:** + +- fsnotify events stop after first secret rotation → subPath mount detected +- "Authentication failed" after Secret update → watch loss or rotation window issue +- Queries return 0 results when logs exist → timestamp format (seconds vs milliseconds) +- 429 errors in bursts → rate limit without backoff +- Grep logs for "token=" or "X-API-TOKEN" → secret leakage + +## Implications for Roadmap + +### Suggested Phase Structure + +**Phase 1: Logz.io Client Foundation (2-3 days)** +- **Delivers:** HTTP client with regional endpoints, query builder, connection validation +- **Components:** RegionalClient, QueryBuilder, health checks +- **Dependencies:** None (uses existing plugin interfaces) +- **Rationale:** Prove API integration works before adding secret complexity +- **Research flag:** NO -

Instead of mounting secrets as files, Spectre will fetch secrets directly from the Kubernetes API server using client-go's SharedInformerFactory. The standard approach uses informers (not raw Watch) for automatic caching, reconnection, and event handling. Secrets are watched via the Kubernetes Watch API, which provides immediate notification on changes without requiring pod restarts. + +The project already uses client-go v0.34.0 (corresponding to Kubernetes 1.34), which provides the complete informer infrastructure needed.

informers handle caching, reconnection, and resync automatically. + +**Example:** +```go +// Source: https://pkg.go.dev/k8s.io/client-go/informers +import ( + "k8s.io/client-go/informers" + "k8s.io/client-go/kubernetes" + "k8s.io/client-go/tools/cache" +) + +// Create factory scoped to namespace +factory := informers.NewSharedInformerFactoryWithOptions( + clientset, + 30*time.Second, // resync period + informers.WithNamespace(namespace), +) + +// Get secret informer +secretInformer := factory.Core().V1().Secrets().Informer() + +// Add event handlers +secretInformer.AddEventHandler(cache.ResourceEventHandlerFuncs{ + AddFunc: func(obj interface{}) { + secret := obj.(*corev1.Secret) + handleSecretUpdate(secret) + }, + UpdateFunc: func(oldObj, newObj interface{}) { + secret := newObj.(*corev1.Secret) + handleSecretUpdate(secret) + }, + DeleteFunc: func(obj interface{}) { + secret := obj.(*corev1.Secret) + handleSecretDelete(secret) + }, +}) + +// Start factory +ctx, cancel := context.WithCancel(context.Background()) +defer cancel() +factory.Start(ctx.Done()) + +// Wait for cache sync +if !cache.WaitForCacheSync(ctx.Done(), secretInformer.HasSynced) { + return fmt.Errorf("failed to sync secret cache") +} +``` + +### Pattern 2: Thread-Safe Token Storage with RWMutex +**What:** Store token in struct with sync.RWMutex, use RLock for reads (concurrent), Lock for writes (exclusive). + +**When to use:** Token reads are frequent (every API call), writes are rare (only on rotation) - RWMutex is optimal for this pattern. + +**Example:** +```go +// Source: https://medium.com/@anto_rayen/understanding-locks-rwmutex-in-golang-3c468c65062a +type SecretWatcher struct { + mu sync.RWMutex + token string + + // Other fields: clientset, informer, namespace, secretName, key +} + +// GetToken is called on every API request (high frequency) +func (w *SecretWatcher) GetToken() (string, error) { + w.mu.RLock() + defer w.mu.RUnlock() + + if w.token == "" { + return "", fmt.Errorf("no token available") + } + return w.token, nil +} + +// setToken is called only on secret rotation (low frequency) +func (w *SecretWatcher) setToken(newToken string) { + w.mu.Lock() + defer w.mu.Unlock() + w.token = newToken +} +``` + +### Pattern 3: In-Cluster Config with RBAC +**What:** Use rest.InClusterConfig() to authenticate as ServiceAccount, configure RBAC to allow get/watch on secrets in same namespace. + +**When to use:** Always when running inside Kubernetes - more secure than kubeconfig file. + +**Example:** +```go +// Source: client-go documentation +import ( + "k8s.io/client-go/kubernetes" + "k8s.io/client-go/rest" +) + +// In-cluster config (uses ServiceAccount token) +config, err := rest.InClusterConfig() +if err != nil { + return fmt.Errorf("failed to get in-cluster config: %w", err) +} + +clientset, err := kubernetes.NewForConfig(config) +if err != nil { + return fmt.Errorf("failed to create clientset: %w", err) +} +``` + +**Required RBAC (deploy with Helm chart):** +```yaml +# Source: https://medium.com/@subhampradhan966/configuring-kubernetes-rbac-a-comprehensive-guide-b6d40ac7b257 +apiVersion: rbac.authorization.k8s.io/v1 +kind: Role +metadata: + name: spectre-secret-reader + namespace: {{ .Release.Namespace }} +rules: +- apiGroups: [""] + resources: ["secrets"] + verbs: ["get", "watch", "list"] +--- +apiVersion: rbac.authorization.k8s.io/v1 +kind: RoleBinding +metadata: + name: spectre-secret-reader + namespace: {{ .Release.Namespace }} +subjects: +- kind: ServiceAccount + name: spectre + namespace: {{ .Release.Namespace }} +roleRef: + kind: Role + name: spectre-secret-reader + apiGroup: rbac.authorization.k8s.io +``` + +### Pattern 4: Secret Data Decoding +**What:** client-go automatically decodes base64 - Secret.Data field is `map[string][]byte` with raw decoded values. + +**When to use:** Always - do NOT manually base64-decode Secret.Data, it's already decoded. + +**Example:** +```go +// Source: https://github.com/kubernetes/client-go/issues/651 +secret, err := clientset.CoreV1().Secrets(namespace).Get(ctx, secretName, metav1.GetOptions{}) +if err != nil { + return fmt.Errorf("failed to get secret: %w", err) +} + +// Data is already base64-decoded by client-go +tokenBytes, ok := secret.Data[key] +if !ok { + return fmt.Errorf("key %q not found in secret %q", key, secretName) +} + +// Trim whitespace (Kubernetes secrets often have trailing newlines) +token := strings.TrimSpace(string(tokenBytes)) +``` + +### Pattern 5: Token Redaction via Custom Type +**What:** Wrap token in custom type with String() method that returns "[REDACTED]" - prevents accidental logging. + +**When to use:** Always for sensitive values - Go's fmt package calls String() automatically. + +**Example:** +```go +// Source: https://medium.com/hackernoon/keep-passwords-and-secrets-out-of-your-logs-with-go-a2294a9546ce +type SecretToken string + +func (t SecretToken) String() string { + return "[REDACTED]" +} + +func (t SecretToken) Value() string { + return string(t) +} + +// Usage +type SecretWatcher struct { + mu sync.RWMutex + token SecretToken // Not string +} + +// Logging automatically redacts +logger.Info("Token updated: %v", watcher.token) // Logs: "Token updated: [REDACTED]" + +// Get actual value when needed +actualToken := watcher.token.Value() +``` + +### Anti-Patterns to Avoid + +- **Using raw Watch API instead of Informer:** Requires manual reconnection on 410 Gone errors, manual caching, manual resync logic - complex and error-prone. + +- **Not scoping informer to namespace:** Watching all secrets in all namespaces requires ClusterRole (security risk) and caches unnecessary data (memory waste). + +- **Blocking in event handlers:** Event handlers run synchronously - long operations block the informer. Use channels/goroutines for heavy work. + +- **Not waiting for cache sync:** Querying lister before WaitForCacheSync completes returns stale/empty data. + +- **Forgetting to close stop channel:** Informer goroutines leak if stop channel never closes - always defer close() or use context cancellation. + +- **Manual base64 decoding of Secret.Data:** client-go already decodes it - double-decoding causes errors. + +## Don't Hand-Roll + +Problems that look simple but have existing solutions: + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| Watching Kubernetes resources | Custom HTTP watch loop with JSON parsing | SharedInformerFactory from client-go | Handles 410 Gone errors, reconnection, exponential backoff, caching, resync - 1000+ lines of complex logic | +| Handling 410 Gone errors | Manual resourceVersion tracking and re-list | Informer's automatic resync | 410 Gone means resourceVersion too old - informer re-lists automatically, you'll get it wrong | +| Kubernetes authentication | Reading ServiceAccount token file manually | rest.InClusterConfig() | Handles token rotation, CA cert loading, API server discovery - security-critical code | +| Secret rotation detection | Polling Get() every N seconds | Watch API via Informer | Watch provides push notifications within ~2 seconds, polling wastes API calls and delays updates | +| Token cache management | Custom cache with expiry logic | Informer's built-in cache (Lister) | Informer cache is thread-safe, automatically updated, indexed - don't reinvent | +| Exponential backoff for retries | Custom backoff with jitter | github.com/cenkalti/backoff (already in project) | Prevents thundering herd, tested formula, configurable limits | + +**Key insight:** Kubernetes operators are complex distributed systems. client-go's informer pattern is the result of years of production experience and bug fixes. Custom watch implementations inevitably rediscover the same edge cases (network partitions, stale caches, goroutine leaks, API throttling) that informers already handle. + +## Common Pitfalls + +### Pitfall 1: Informer Goroutine Leaks on Shutdown +**What goes wrong:** Informer starts background goroutines that run until stop channel closes. If stop channel never closes (or context never cancels), goroutines leak, causing memory growth over time. + +**Why it happens:** factory.Start(stopCh) spawns goroutines for each informer, but returns immediately. Easy to forget to close stopCh on application shutdown. + +**How to avoid:** +- Always use context.WithCancel() and defer cancel() +- Or create stop channel and defer close(stopCh) +- Call factory.Shutdown() in Stop() method (blocks until all goroutines exit) + +**Warning signs:** +- Increasing goroutine count in pprof (net/http/pprof) +- Memory growth without corresponding resource increase +- Test failures with goleak.VerifyNone() showing leaked goroutines + +**Example:** +```go +// Source: https://medium.com/uckey/memory-goroutine-leak-with-rancher-kubernetes-custom-controller-with-client-go-9e296c815209 +// WRONG - stop channel never closed +func (i *Integration) Start(ctx context.Context) error { + factory := informers.NewSharedInformerFactory(clientset, 30*time.Second) + stopCh := make(chan struct{}) + factory.Start(stopCh) // Goroutines run forever + return nil +} + +// RIGHT - context cancellation stops informer +func (i *Integration) Start(ctx context.Context) error { + factory := informers.NewSharedInformerFactory(clientset, 30*time.Second) + factory.Start(ctx.Done()) // Goroutines stop when ctx cancelled + return nil +} + +func (i *Integration) Stop(ctx context.Context) error { + i.cancel() // Cancel context from Start() + i.factory.Shutdown() // Wait for goroutines to exit + return nil +} +``` + +### Pitfall 2: Watch Reconnection After 410 Gone Error +**What goes wrong:** Kubernetes watch connections can expire if resourceVersion becomes too old (API server has compacted history). Watch returns 410 Gone error. If not handled, watch stops receiving updates permanently. + +**Why it happens:** Kubernetes API server only keeps a limited history of resource versions. If watch disconnects for too long (network partition, API server restart), the old resourceVersion is gone when reconnecting. + +**How to avoid:** Use Informer instead of raw Watch - informer automatically handles 410 Gone by re-listing all resources and restarting watch with fresh resourceVersion. + +**Warning signs:** +- Secret rotations stop being detected after Spectre pod restart or network issue +- Logs show "resourceVersion too old" or "410 Gone" errors +- Integration remains in degraded state despite valid secret existing + +**Example:** +```go +// Source: https://github.com/kubernetes/kubernetes/issues/25151 +// WRONG - raw Watch doesn't handle 410 Gone +watcher, err := clientset.CoreV1().Secrets(namespace).Watch(ctx, metav1.ListOptions{}) +for event := range watcher.ResultChan() { + // If watch connection expires, this loop ends and never restarts +} + +// RIGHT - Informer handles 410 Gone automatically +factory := informers.NewSharedInformerFactory(clientset, 30*time.Second) +secretInformer := factory.Core().V1().Secrets().Informer() +secretInformer.AddEventHandler(cache.ResourceEventHandlerFuncs{ + UpdateFunc: func(old, new interface{}) { + // Always receives updates, even after 410 Gone (informer re-lists) + }, +}) +factory.Start(ctx.Done()) +``` + +### Pitfall 3: Blocking Operations in Event Handlers +**What goes wrong:** Event handlers (AddFunc, UpdateFunc, DeleteFunc) run synchronously in the informer's goroutine. Long-running operations (API calls, database writes, heavy computation) block the handler, preventing other events from processing. + +**Why it happens:** Informer delivers events one-by-one to handlers. If handler takes 10 seconds, next event waits 10 seconds - creates cascading delays. + +**How to avoid:** +- Keep handlers fast (<1ms) - just validate and copy data +- Use buffered channel to queue work for background goroutine +- Or spawn goroutine in handler (but beware unbounded goroutine growth) + +**Warning signs:** +- Slow secret rotation detection (>5 seconds when should be <2 seconds) +- Logs showing "cache sync took 30s" warnings +- Other resources (pods, configmaps) also slow to update + +**Example:** +```go +// WRONG - blocks informer for 5 seconds per secret +secretInformer.AddEventHandler(cache.ResourceEventHandlerFuncs{ + UpdateFunc: func(old, new interface{}) { + secret := new.(*corev1.Secret) + validateToken(secret) // Calls external API - 5 seconds + updateDatabase(secret) // Database write - 2 seconds + }, +}) + +// RIGHT - handler returns immediately, work happens async +type SecretWatcher struct { + workQueue chan *corev1.Secret +} + +secretInformer.AddEventHandler(cache.ResourceEventHandlerFuncs{ + UpdateFunc: func(old, new interface{}) { + secret := new.(*corev1.Secret) + // Non-blocking send (or use select with default) + select { + case w.workQueue <- secret: + default: + logger.Warn("Work queue full, dropping secret update") + } + }, +}) + +// Background worker processes queue +go func() { + for secret := range w.workQueue { + validateToken(secret) + updateDatabase(secret) + } +}() +``` + +### Pitfall 4: Race Condition Between Token Read and Update +**What goes wrong:** Multiple goroutines read token (API calls) while one goroutine updates token (secret rotation). Without proper locking, reads can see partial writes (empty string, corrupted value) causing API auth failures. + +**Why it happens:** Go strings are not atomic - even simple assignment can be observed mid-write by concurrent reader on different CPU core. + +**How to avoid:** +- Use sync.RWMutex - RLock for reads (concurrent), Lock for writes (exclusive) +- Or use atomic.Value if token storage is simple (just string, no validation) +- Test with race detector: go test -race + +**Warning signs:** +- Intermittent "invalid token" errors during secret rotation +- Race detector warnings in tests: "WARNING: DATA RACE" +- Auth failures that resolve after retrying + +**Example:** +```go +// WRONG - no synchronization +type SecretWatcher struct { + token string // RACE: concurrent read/write +} + +func (w *SecretWatcher) GetToken() string { + return w.token // RACE: reads while Update() writes +} + +func (w *SecretWatcher) Update(secret *corev1.Secret) { + w.token = parseToken(secret) // RACE: writes while GetToken() reads +} + +// RIGHT - RWMutex protects token +type SecretWatcher struct { + mu sync.RWMutex + token string +} + +func (w *SecretWatcher) GetToken() (string, error) { + w.mu.RLock() + defer w.mu.RUnlock() + if w.token == "" { + return "", fmt.Errorf("no token available") + } + return w.token, nil +} + +func (w *SecretWatcher) Update(secret *corev1.Secret) { + newToken := parseToken(secret) + w.mu.Lock() + w.token = newToken + w.mu.Unlock() +} +``` + +### Pitfall 5: Not Trimming Whitespace from Secret Values +**What goes wrong:** Kubernetes secrets often have trailing newlines when created via kubectl or YAML (common editor behavior). Token comparison fails: "token123\n" != "token123". + +**Why it happens:** Users create secrets like: `kubectl create secret generic my-secret --from-literal=token="$(cat token.txt)"` where token.txt has trailing newline. Or YAML editors add newlines. + +**How to avoid:** Always strings.TrimSpace() after decoding Secret.Data - removes leading/trailing whitespace including newlines. + +**Warning signs:** +- Secret exists with correct value in kubectl output +- Integration remains degraded with "invalid token" error +- Token length differs from expected (len("token123\n") == 9, not 8) + +**Example:** +```go +// Source: Common kubectl secret creation pattern +// WRONG - uses raw bytes including whitespace +tokenBytes := secret.Data[key] +token := string(tokenBytes) // May be "token123\n" +client.SetToken(token) // Fails: API expects "token123" + +// RIGHT - trim whitespace +tokenBytes := secret.Data[key] +token := strings.TrimSpace(string(tokenBytes)) // Now "token123" +if token == "" { + return fmt.Errorf("token is empty after trimming whitespace") +} +client.SetToken(token) // Success +``` + +### Pitfall 6: Informer Resync Storms During Network Partition +**What goes wrong:** If resync period is too short (e.g., 1 second) and network is flaky, informer constantly re-lists all secrets, flooding API server and causing throttling (HTTP 429). + +**Why it happens:** Resync period triggers full re-list of all resources in namespace. If network drops during re-list, informer retries immediately - exponential API load. + +**How to avoid:** +- Use resync period ≥30 seconds (30s is common default) +- Don't set resync to 0 (disables resync entirely - stale cache risk) +- Monitor API server metrics for high secret list request rate + +**Warning signs:** +- API server logs show HTTP 429 (Too Many Requests) from Spectre +- Spectre logs show "rate limited" or "throttled" messages +- Secret updates delayed during high API server load + +**Example:** +```go +// WRONG - 1 second resync floods API server +factory := informers.NewSharedInformerFactory(clientset, 1*time.Second) + +// RIGHT - 30 second resync (standard) +factory := informers.NewSharedInformerFactory(clientset, 30*time.Second) + +// ALSO RIGHT -

What we know: atomic.Value is ~3x faster (0.5ns vs 48ns per read), RWMutex better for complex data structures + - What's unclear: Whether token validation logic (empty check, whitespace trim) happens inside or outside lock + -

What we know: Informer has built-in reconnection, cenkalti/backoff provides configurable backoff + - What's unclear: Whether informer's default backoff is sufficient or needs tuning + - Recommendation: Use informer's built-in reconnection (already handles backoff), add custom backoff only if logs show excessive retries + +## Sources + +### Primary (HIGH confidence) +- [k8s.io/client-go/informers](https://pkg.go.dev/k8s.io/client-go/informers) -

Overview Tool with Parallel Aggregations +**What:** Execute 3 parallel queries (total, errors, warnings) for namespace-level summary +**When to use:** Overview tool implementation +**Example:** +```go +// Source: internal/integration/victorialogs/tools_overview.go:39-112 +func (t *OverviewTool) Execute(ctx context.Context, args []byte) (interface{}, error) { + // Parse params and build base query + var params OverviewParams + json.Unmarshal(args, ¶ms) + + // Execute 3 aggregation queries in parallel + resultCh := make(chan queryResult, 3) + + // Query 1: Total logs per namespace (terms aggregation) + go func() { + agg := map[string]interface{}{ + "query": buildBaseQuery(params), + "aggs": map[string]interface{}{ + "by_namespace": map[string]interface{}{ + "terms": map[string]interface{}{ + "field": "kubernetes.namespace.keyword", + "size": 1000, // Max allowed by Logz.io + }, + }, + }, + "size": 0, // No hits, only aggregations + } + result, err := t.ctx.Client.QueryAggregation(ctx, agg) + resultCh <- queryResult{name: "total", result: result, err: err} + }() + + // Query 2: Error logs (with regex filter) + go func() { + params := params + params.RegexMatch = GetErrorPattern() + // ... similar aggregation query + resultCh <- queryResult{name: "error", result: result, err: err} + }() + + // Query 3: Warning logs + // ... similar pattern + + // Collect and merge results (same as VictoriaLogs) + return aggregateResults(totalResult, errorResult, warnResult) +} +``` + +### Anti-Patterns to Avoid +- **Leading wildcards in queries:** Logz.io explicitly disables `*prefix` queries - validate and reject with helpful error +- **Missing result limits:** Always set `size` parameter (default 100, max 1000) to prevent API errors +- **Bearer token auth:** Logz.io uses `X-API-TOKEN` header, not `Authorization: Bearer` +- **Nested bucket aggregations:** Logz.io restricts nesting 2+ bucket aggregations (date_histogram, terms, etc.) + +## Don't Hand-Roll + +Problems that look simple but have existing solutions: + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| Query DSL construction | String templates | Programmatic map building | Type safety, easier testing, handles escaping | +| Severity detection | Custom regex per tool | Shared severity.go patterns | VictoriaLogs patterns proven across 1000s of logs | +| Time range parsing | Custom parser | VictoriaLogs TimeRangeParams | Handles Unix seconds/ms, defaults to 1h | +| Tool parameter schemas | Inline JSON strings | map[string]interface{} | Matches mcp-go registration pattern | +| Result normalization | Direct pass-through | LogEntry struct mapping | Consistent format across integrations | +| API token management | Env vars | SecretWatcher from Phase 11 | Dynamic updates, no restarts, proven pattern | + +**Key insight:** VictoriaLogs implementation (Phase 4) solved 90% of these problems. The Logz.io implementation primarily translates LogsQL → Elasticsearch DSL; tool skeleton and patterns are identical. + +## Common Pitfalls + +### Pitfall 1: Leading Wildcard Queries +**What goes wrong:** User queries like `*error` fail with cryptic Elasticsearch errors +**Why it happens:** Logz.io requires `allow_leading_wildcard: false` for performance +**How to avoid:** Validate query parameters and reject with helpful message: +```go +if strings.HasPrefix(params.Query, "*") || strings.HasPrefix(params.Query, "?") { + return nil, fmt.Errorf("leading wildcard queries (*prefix or ?prefix) are not supported by Logz.io - try using suffix wildcards (prefix*) or remove the wildcard") +} +``` +**Warning signs:** 400 errors from Logz.io API mentioning `allow_leading_wildcard` + +### Pitfall 2: Aggregation Size Limits +**What goes wrong:** Overview queries return truncated results without warning +**Why it happens:** Logz.io silently caps aggregation size at 1000 buckets +**How to avoid:** Always set explicit size in terms aggregations: +```go +"terms": map[string]interface{}{ + "field": "kubernetes.namespace.keyword", + "size": 1000, // Logz.io max for aggregated results +} +``` +**Warning signs:** Namespace counts mysteriously stop at certain number + +### Pitfall 3: Rate Limit (429) Handling +**What goes wrong:** Parallel queries trigger rate limits, requests fail +**Why it happens:** Logz.io limits to 100 concurrent requests per account +**How to avoid:** Return immediate error (no retry) with clear message: +```go +if resp.StatusCode == 429 { + return nil, fmt.Errorf("rate limit exceeded: Logz.io allows max 100 concurrent API requests - reduce parallel tool calls or increase time between requests") +} +``` +**Warning signs:** Intermittent 429 errors during high tool usage + +### Pitfall 4: Keyword vs Text Fields +**What goes wrong:** Filters return no results despite matching data existing +**Why it happens:** Elasticsearch analyzes text fields (splits on spaces), requires `.keyword` suffix for exact match +**How to avoid:** Always use `.keyword` suffix for exact match filters: +```go +// WRONG: "kubernetes.namespace": "prod" (analyzed, matches "prod staging") +// RIGHT: "kubernetes.namespace.keyword": "prod" (exact match) + +"term": map[string]interface{}{ + "kubernetes.namespace.keyword": params.Namespace, // Note .keyword suffix +} +``` +**Warning signs:** Filters "don't work" but Kibana UI shows matching logs + +### Pitfall 5: Time Range Format Confusion +**What goes wrong:** Time filters return empty results or wrong time window +**Why it happens:** Logz.io expects RFC3339 format in `@timestamp` field, not Unix timestamps +**How to avoid:** Always format time as RFC3339: +```go +"range": map[string]interface{}{ + "@timestamp": map[string]interface{}{ + "gte": timeRange.Start.Format(time.RFC3339), // 2026-01-22T10:00:00Z + "lte": timeRange.End.Format(time.RFC3339), + }, +} +``` +**Warning signs:** Queries return 0 results despite logs existing in time range + +### Pitfall 6: Authentication Header Format +**What goes wrong:** All API calls fail with 401 Unauthorized +**Why it happens:** Using wrong header name or format +**How to avoid:** Use exact header format from Logz.io docs: +```go +// WRONG: req.Header.Set("Authorization", "Bearer " + token) +// RIGHT: +req.Header.Set("X-API-TOKEN", token) +``` +**Warning signs:** Consistent 401 errors despite valid token + +## Code Examples + +Verified patterns from official sources: + +### Elasticsearch Terms Aggregation for Namespace Grouping +```go +// Source: Elasticsearch DSL reference (verified against Logz.io API docs) +// https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html

Subject: [PATCH 182/342] feat(12-01): implement Elasticsearch DSL query builder with authentication MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Client implementation (client.go): - Created Client struct with SecretWatcher integration - Implemented QueryLogs with X-API-TOKEN authentication header - Implemented QueryAggregation with terms aggregation support - Added error handling: 401/403 (auth), 429 (rate limit), other errors - Created parseLogzioHit for normalizing Elasticsearch hits to LogEntry - Field mapping: kubernetes.namespace, kubernetes.pod_name, kubernetes.container_name Query builder (query.go): - BuildLogsQuery generates Elasticsearch DSL with bool query - Time range filter on @timestamp with RFC3339 formatting - Exact match filters with .keyword suffix (namespace, pod, container, level) - Regexp filter on message field with case_insensitive flag - BuildAggregationQuery with terms aggregation (size 1000, order by _count desc) - ValidateQueryParams rejects leading wildcards and enforces max limit 500 Tests (query_test.go): - TestBuildLogsQuery: Basic query structure validation - TestBuildLogsQueryWithFilters: Verify .keyword suffixes on all exact-match fields - TestBuildLogsQueryTimeRange: RFC3339 time formatting - TestBuildLogsQueryRegexMatch: Regexp clause structure - TestBuildAggregationQuery: Terms aggregation with .keyword suffix - TestValidateQueryParams_LeadingWildcard: Reject *prefix and ?prefix patterns - TestValidateQueryParams_MaxLimit: Enforce 500 max limit - Coverage: 20.8% (focused on query builder logic) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- internal/integration/logzio/client.go | 269 ++++++++++++++

The implementation reuses the existing Drain algorithm infrastructure in `internal/logprocessing/` which has already been extracted as common code.

+**Source:** `/home/moritz/dev/spectre-via-ssh/internal/logprocessing/store.go` + +### Pattern 3: MCP Tool Registration (Integration Pattern) +**What:** Dynamic tool registration during integration startup +**When to use:** All integrations register tools in RegisterTools method +**Example:** +```go +// From internal/integration/victorialogs/victorialogs.go +func (v *VictoriaLogsIntegration) RegisterTools(registry integration.ToolRegistry) error { + // Create tool context + toolCtx := ToolContext{ + Client: v.client, + Logger: v.logger, + Instance: v.name, + } + + // Register patterns tool: victorialogs_{name}_patterns + patternsTool := &PatternsTool{ + ctx: toolCtx, + templateStore: v.templateStore, + } + patternsName := fmt.Sprintf("victorialogs_%s_patterns", v.name) + patternsSchema := map[string]interface{}{ + "type": "object", + "properties": map[string]interface{}{ + "namespace": map[string]interface{}{ + "type": "string", + "description": "Kubernetes namespace to query (required)", + }, + "severity": map[string]interface{}{ + "type": "string", + "description": "Optional: filter by severity level (error, warn)", + "enum": []string{"error", "warn"}, + }, + // ... other parameters + }, + "required": []string{"namespace"}, + } + err := registry.RegisterTool(patternsName, "Get aggregated log patterns with novelty detection", patternsTool.Execute, patternsSchema) +} +``` +**Source:** `/home/moritz/dev/spectre-via-ssh/internal/integration/victorialogs/victorialogs.go` + +### Pattern 4: Time Range Parsing with Defaults +**What:** Consistent time range handling across tools +**When to use:** All log tools use this pattern +**Example:** +```go +// From internal/integration/victorialogs/tools_patterns.go +type TimeRangeParams struct { + StartTime int `json:"start_time,omitempty"` // Unix seconds or millis + EndTime int `json:"end_time,omitempty"` // Unix seconds or millis +} + +func parseTimeRange(params TimeRangeParams) TimeRange { + now := time.Now() + start := parseTimestamp(params.StartTime, now.Add(-1*time.Hour)) + end := parseTimestamp(params.EndTime, now) + return TimeRange{Start: start, End: end} +} + +func parseTimestamp(ts int, defaultTime time.Time) time.Time { + if ts == 0 { + return defaultTime + } + // Handle both seconds and milliseconds + if ts > 1e12 { + return time.Unix(0, int64(ts)*int64(time.Millisecond)) + } + return time.Unix(int64(ts), 0) +} +``` + +### Pattern 5: Log Sampling for Pattern Mining +**What:** Fetch sufficient logs for pattern diversity without overwhelming memory +**When to use:** Pattern mining tools need representative samples +**Example:** +```go +// From internal/integration/victorialogs/tools_patterns.go +func (t *PatternsTool) fetchLogsWithSampling(ctx context.Context, namespace, severity string, timeRange TimeRange, targetSamples int) ([]LogEntry, error) { + // For pattern mining, fetch targetSamples * 20 (e.g., 50 * 20 = 1000 logs) + // This gives enough logs for meaningful pattern extraction + maxLogs := targetSamples * 20 + if maxLogs < 500 { + maxLogs = 500 // Minimum 500 logs + } + if maxLogs > 5000 { + maxLogs = 5000 // Cap at 5000 to avoid memory issues + } + + // Build query with limit + query := QueryParams{ + TimeRange: timeRange, + Namespace: namespace, + Limit: maxLogs, + } + + // Apply severity filter + switch severity { + case "error": + query.RegexMatch = GetErrorPattern() + case "warn": + query.RegexMatch = GetWarningPattern() + } + + return t.ctx.Client.QueryLogs(ctx, query) +} +``` + +### Pattern 6: Novelty Detection via Time Window Comparison +**What:** Detect new patterns by comparing current to previous time window +**When to use:** All patterns tools implement this for anomaly detection +**Example:** +```go +// From internal/integration/victorialogs/tools_patterns.go +// Current window +currentLogs, _ := fetchLogsWithSampling(ctx, namespace, severity, timeRange, limit) +currentTemplates, metadata := mineTemplatesWithMetadata(namespace, currentLogs) + +// Previous window = same duration immediately before current +duration := timeRange.End.Sub(timeRange.Start) +previousTimeRange := TimeRange{ + Start: timeRange.Start.Add(-duration), + End: timeRange.Start, +} + +// Previous window (no metadata needed) +previousLogs, _ := fetchLogsWithSampling(ctx, namespace, severity, previousTimeRange, limit) +previousTemplates := mineTemplates(namespace, previousLogs) + +// Detect novel patterns +novelty := t.templateStore.CompareTimeWindows(namespace, currentTemplates, previousTemplates) +// novelty[templateID] = true if pattern exists in current but not previous + +// Mark templates +for _, tmpl := range currentTemplates { + pt := PatternTemplate{ + Pattern: tmpl.Pattern, + Count: tmpl.Count, + IsNovel: novelty[tmpl.ID], // Flag from comparison + } + templates = append(templates, pt) +} +``` + +### Anti-Patterns to Avoid +- **Sharing TemplateStore across backends:** Each integration needs its own instance - VictoriaLogs and Logz.io patterns must not interfere with each other +- **Processing all logs without limits:** Pattern mining must cap at 5000 logs to prevent memory exhaustion +- **Merging current and previous logs before mining:** Must mine separately then compare - otherwise can't detect novelty +- **Forgetting .keyword suffix for Elasticsearch:** Logz.io aggregations need `.keyword` suffix for exact matching (e.g., `kubernetes.namespace.keyword`) + +## Don't Hand-Roll + +Problems that look simple but have existing solutions: + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| Log template mining | Custom regex or heuristic clustering | `internal/logprocessing.TemplateStore` | Drain algorithm is research-proven, handles variable patterns, already extracted and production-tested | +| Variable masking | Simple regex replace | `logprocessing.AggressiveMask` | Masks 10+ variable types (IP, UUID, hex, paths, emails, timestamps) in correct order, preserves HTTP status codes | +| Template ID generation | Sequential integers or random UUIDs | `logprocessing.GenerateTemplateID` | SHA-256 hash of namespace+pattern gives stable IDs across restarts and clients | +| Namespace-scoped storage | Global map with namespace prefix keys | `TemplateStore` with `NamespaceTemplates` | Thread-safe with proper locking, lazy namespace creation, isolated Drain instances per namespace | +| Time window comparison | Manual set operations | `TemplateStore.CompareTimeWindows` | Compares by pattern (not ID) for cross-window matching, handles edge cases | +| Log normalization | ad-hoc preprocessing | `logprocessing.PreProcess` | Consistent lowercase/trim, JSON message extraction | + +**Key insight:** Pattern mining has subtle edge cases (wildcard normalization, namespace isolation, thread safety) that are already solved. The VictoriaLogs implementation took multiple iterations to get right - don't repeat that learning curve. + +## Common Pitfalls + +### Pitfall 1: Forgetting to Initialize TemplateStore in Integration +**What goes wrong:** PatternsTool receives nil templateStore, panics on Process() call +**Why it happens:** Integration struct needs templateStore field, must be initialized in Start() method +**How to avoid:** +```go +// In logzio.go +type LogzioIntegration struct { + // ...existing fields... + templateStore *logprocessing.TemplateStore // ADD THIS +} + +// In Start() method +func (l *LogzioIntegration) Start(ctx context.Context) error { + // ...existing initialization... + + // Initialize template store for pattern mining + l.templateStore = logprocessing.NewTemplateStore(logprocessing.DefaultDrainConfig()) + + return nil +} + +// In RegisterTools() method -

-Adding Logz.io integration and secret management introduces complexity across multiple dimensions: Elasticsearch DSL query limitations, multi-region configuration, rate limiting, scroll API lifecycle, fsnotify edge cases, and Kubernetes secret refresh mechanics. Critical pitfalls cluster around three areas: - -1. **Elasticsearch DSL query constraints** - Leading wildcards disabled, analyzed field limitations, scroll API expiration -2. **Secret rotation mechanics** - Kubernetes subPath breaks hot-reload, fsnotify misses atomic writes, race conditions during rotation -3. **Multi-region correctness** - Hard-coded endpoints, region-specific rate limits, credential scope confusion +## Critical Pitfalls -Many of these are subtle correctness issues that manifest in production under load, not during development. This research identifies early warning signs and prevention strategies for each. +Mistakes that cause rewrites or major issues. --- -## Critical Pitfalls - -Mistakes that cause rewrites, data loss, or security incidents. - -### Pitfall 1: Kubernetes Secret subPath Breaks Hot-Reload +### Pitfall 1: Grafana API Version Breaking Changes -**What goes wrong:** -When secrets are mounted with `subPath`, Kubernetes updates the volume symlink but NOT the actual file bind-mounted into the container. Your fsnotify watcher detects no changes, application never reloads credentials, and you get authentication failures after secret rotation. +**What goes wrong:** Dashboard JSON schema changes between major Grafana versions break parsing logic. The dashboard schema changed significantly in v11 (URL structure for repeated panels) and v12 (new schema format). -**Why it happens:** -Kubernetes atomic writer uses symlinks for volume updates. With `subPath`, the symlink update happens at the mount point, not at the file level. The existing VictoriaLogs fsnotify watcher (`.planning/research/integration_watcher.go`) watches the file directly, which becomes stale with `subPath` mounts. +**Why it happens:** Grafana's HTTP API follows alpha/beta/GA stability levels. Alpha APIs can have breaking changes without notice. GA APIs are stable but dashboard schema evolves independently. **Consequences:** -- Secret rotation causes downtime (authentication fails) -- Monitoring alerts fire during rotation windows -- Manual pod restarts required to pick up new secrets -- Violates zero-downtime rotation requirement +- Dashboard ingestion fails silently when new schema fields appear +- Panel parsing breaks when `gridPos` structure changes +- Variable interpolation fails when template syntax evolves +- Repeated panel URLs (`&viewPanel=panel-5` → `&viewPanel=panel-3-clone1`) become invalid across versions **Prevention:** -1. **DO NOT use `subPath` for secret mounts** - Mount entire secret volume, reference by path -2. Document in deployment YAML with explicit comment warning against subPath -3. Add integration test that verifies hot-reload with volume mount (not subPath) -4. Consider Secrets Store CSI Driver with Reloader for external vaults +1. **Store raw dashboard JSON** — Always persist complete JSON before parsing. When parsing fails, fall back to raw storage and log for investigation. +2. **Version detection** — Check `schemaVersion` field (integer in dashboard JSON) and handle known versions explicitly. +3. **Defensive parsing** — Use optional field extraction. If `gridPos` is missing, infer from panel order. If `targets` array is empty, log warning but continue. +4. **Schema evolution tests** — Test against Grafana v9, v10, v11, v12 dashboard exports. Create fixture files for each. **Detection:** -- Warning sign: fsnotify events stop after first secret rotation -- Warning sign: Pod logs show "authentication failed" after secret update -- Test: Update secret, watch for fsnotify event within 60s (kubelet sync period) +- Dashboard ingestion succeeds but panels array is empty +- Queries array exists but metric extraction returns zero results +- `schemaVersion` in logs is higher than tested versions -**References:** -- [Kubernetes Secrets and Pod Restarts](https://blog.ascendingdc.com/kubernetes-secrets-and-pod-restarts) -- [Known Limitations - Secrets Store CSI Driver](https://secrets-store-csi-driver.sigs.k8s.io/known-limitations) -- [K8s Deployment Automatic Rollout Restart](https://igboie.medium.com/k8s-deployment-automatic-rollout-restart-when-referenced-secrets-and-configmaps-are-updated-0c74c85c1b4a) +**Affected phases:** Phase 1 (Grafana client), Phase 2 (graph schema), Phase 6 (MCP tools) -**Which phase:** -Phase 2 (Logz.io API Client) - Must establish secret loading pattern before MCP tools implementation +**References:** +- [Grafana v11 Breaking Changes](https://grafana.com/docs/grafana/latest/breaking-changes/breaking-changes-v11-0/) +- [Dashboard JSON Schema](https://grafana.com/docs/grafana/latest/visualizations/dashboards/build-dashboards/view-dashboard-json-model/) +- [Schema V2 Resource](https://grafana.com/docs/grafana/latest/as-code/observability-as-code/schema-v2/) --- -### Pitfall 2: Atomic Editor Saves Cause fsnotify Watch Loss +### Pitfall 2: Service Account Token Scope Confusion -**What goes wrong:** -Text editors (vim, VSCode, kubectl) use atomic writes: write temp file → rename to target. fsnotify watches the inode, which changes on rename. Watch is automatically removed, fsnotify stops receiving events, and config changes are silently ignored. +**What goes wrong:** Service account tokens created in Grafana Cloud have different permissions than self-hosted Grafana. Tokens work for dashboard reads but fail for Admin/User API endpoints. Authentication method (Basic auth vs Bearer) varies between Cloud and self-hosted. -**Why it happens:** -The existing `integration_watcher.go` handles this with Remove/Rename event re-watching (lines 140-148), BUT there's a 50ms sleep gap where the file might be written and you miss the event. Kubernetes Secret volume updates are atomic writes. VSCode triggers 5 events per save, creating race conditions in the debounce logic. +**Why it happens:** Service accounts are limited to an organization and organization role. They cannot be granted Grafana server administrator permissions. Admin HTTP API and User HTTP API require Basic authentication with server admin role. **Consequences:** -- Secret rotation silently fails (no reload triggered) -- Integration continues using expired credentials until health check fails -- Gap between rotation and detection creates security window -- Difficult to debug (no error, just missing events) +- Token works in development (self-hosted with admin user) but fails in production (Cloud with service account) +- User attempts to list all dashboards via Admin API but gets 403 Forbidden +- Dashboard export works but version history API fails (requires `dashboards:write` since Grafana v11) **Prevention:** -1. **Verify existing re-watch logic handles Kubernetes volume updates** - Test with actual Secret mount -2. **Increase re-watch delay from 50ms to 200ms** for Kubernetes atomic writes (slower than editor saves) -3. **Watch parent directory, not file** - Recommended by fsnotify docs (avoids inode change problem) -4. **Add file existence check after re-watch** - Verify file exists before continuing -5. **Log all watch removals and re-additions** - Make missing events visible +1. **Separate auth paths** — Detect Grafana Cloud vs self-hosted via base URL pattern (`grafana.com` vs custom domain).

User tries query like `*-service` to find all services, gets error. This is NOT documented clearly in their API docs, only buried in their UI help. +**What goes wrong:** PromQL has no formal grammar definition. The official parser is a handwritten recursive-descent parser with "hidden features and edge cases that nobody is aware of." Building a custom parser leads to incompatibilities with valid PromQL. -**Why it happens:** -Leading wildcards require scanning every term in the index (extremely expensive). Logz.io disables this for performance/cost reasons. Standard Elasticsearch clients default to allowing it, creating mismatch with Logz.io API expectations. +**Why it happens:** PromQL evolved organically. The Prometheus team acknowledges that "none of the active members has a deep understanding of the parser code." Third-party parsers (Go, C#, Python) handle different edge cases differently. **Consequences:** -- MCP tool queries fail with cryptic errors -- Users familiar with Elasticsearch expect this to work -- Workarounds (use filters, analyzed fields) are non-obvious -- Degrades user experience of AI assistant tools +- Valid PromQL from Grafana dashboard fails to parse: `rate(http_requests_total[5m])` works but `rate(http_requests_total{job=~"$job"}[5m])` breaks on variable interpolation +- Binary expression constraints are inconsistent: "comparisons between scalars must use BOOL modifier" but not enforced everywhere +- Nested function calls parse incorrectly: `histogram_quantile(0.95, sum(rate(...)) by (le))` loses grouping context **Prevention:** -1. **Document leading wildcard limitation prominently** in MCP tool descriptions -2. **Validate queries before sending to API** - Reject leading wildcards with helpful error -3. **Suggest alternatives in error message** - "Use field filters instead of leading wildcards" -4. **Pre-query field mapping check** - Identify analyzed fields that support tokenized search -5. **Add query builder helper** that constructs valid Logz.io queries +1. **Best-effort parsing** — Accept PROJECT.md constraint: "Complex expressions may not fully parse, extract what's possible."

If MCP tool takes >20min to process results (e.g., pattern mining large dataset), scroll_id becomes invalid. Subsequent scroll requests fail with "expired scroll ID" error, and you lose your pagination state. +**What goes wrong:** Creating a node for every metric time series (e.g., `http_requests_total{job="api", status="200"}`) explodes graph size. 10K metrics × 100 label combinations = 1M nodes. FalkorDB traversals become slow. -**Why it happens:** -Scroll contexts hold cluster resources (search state, results cache). 20-minute timeout is aggressive compared to Elasticsearch default (1 minute, but adjustable). The project context mentions this limit but doesn't explain implications for long-running operations. +**Why it happens:** Observability data has high cardinality. A single Prometheus instance can have millions of unique time series. Treating each series as a graph node ignores that time-series databases are purpose-built for this scale. **Consequences:** -- Pattern mining tool fails mid-operation on large namespaces -- Partial results without clear indication of incompleteness -- User retries query, hits rate limit, degrades service -- Cannot paginate through large result sets (>10,000 logs) +- Graph ingestion takes minutes instead of seconds +- Cypher queries timeout when traversing metric relationships +- Memory usage grows unbounded (1M nodes × avg 500 bytes = 500MB just for metric nodes) +- Dashboard hierarchy traversal (Overview→Detail) is slower than querying Grafana directly **Prevention:** -1. **Use scroll API only for result sets needing >1,000 logs** (Logz.io aggregation limit) -2. **Set aggressive internal timeout (15 min)** - Leave 5min buffer before API expiration -3. **Implement checkpoint/resume** - Save last processed position, allow restart -4. **Consider Point-in-Time API** if Logz.io supports it (newer alternative to scroll) -5. **Stream results to caller incrementally** - Don't buffer entire dataset in memory -6. **Clear scroll context after use** - Free resources promptly +1. **Schema hierarchy** — Store structure, not data: + - **Dashboard** node (dozens): `{uid, title, tags, level: overview|aggregated|detail}` + - **Panel** node (hundreds): `{id, title, type, gridPos}` + - **Query** node (hundreds): `{refId, expr: raw PromQL, datasource}` + - **Metric template** node (thousands): `{name: "http_requests_total", labels: ["job", "status"]}` — no label values + - **Service** node (dozens): `{name: inferred from job/service label}` -**Detection:** -- Warning sign: Long-running queries (>10min) fail with scroll errors -- Warning sign: Memory usage grows unbounded during pattern mining -- Test: Query with scroll, sleep 21 minutes, attempt next page (expect error handling) - -**References:** -- [Elasticsearch Scroll API](https://www.elastic.co/guide/en/elasticsearch/reference/current/scroll-api.html) -- [Elasticsearch Error: Cannot retrieve scroll context](https://pulse.support/kb/elasticsearch-cannot-retrieve-scroll-context-expired-scroll-id) -- [Elasticsearch Pagination by Scroll API](https://medium.com/eatclub-tech/elasticsearch-pagination-by-scroll-api-68d36b8f4972) - -**Which phase:** -Phase 3 (MCP Tool Implementation) - Affects patterns tool querying large datasets - ---- +2. **Do NOT create nodes for:** + - Individual time series (e.g., `http_requests_total{job="api"}`) + - Metric values or timestamps + - Label value combinations -### Pitfall 5: Hard-Coded API Region Endpoint +3. **Relationships:** + - `(Dashboard)-[:CONTAINS]->(Panel)` + - `(Panel)-[:QUERIES]->(Query)` + - `(Query)-[:MEASURES]->(MetricTemplate)` + - `(MetricTemplate)-[:BELONGS_TO]->(Service)` — inferred from labels -**What goes wrong:** -Logz.io uses different API endpoints per region (us-east-1, eu-central-1, ap-southeast-2, etc.).

These end up in pod logs, aggregated into VictoriaLogs/Logz.io, and become searchable by anyone with log access. +**What goes wrong:** Anomaly detection compares current metrics to 7-day average but doesn't account for seasonality (weekday vs weekend) or concept drift (deployment changes baseline). Results in false positives ("CPU is high!" but it's Monday morning) or false negatives (gradual memory leak is "normal"). -**Why it happens:** -Secrets are just strings, no type-level protection. Generic error messages include full context ("failed to connect with token=abc123..."). Structured logging makes it easy to log entire config objects. Existing VictoriaLogs integration has generic logging, no secret scrubbing. +**Why it happens:** Time-series data has multiple seasonal patterns (hourly, daily, weekly). Simple rolling average doesn't distinguish "10am on Monday" from "2am on Sunday." Systems change over time (new features, scaling events) so old baselines become invalid. **Consequences:** -- Credential leakage to logs (security incident) -- Compliance violation (secrets in plaintext in log storage) -- Difficult to detect/remediate (secrets may be in historical logs) -- Incident response requires log deletion (may violate retention policies) +- High false positive rate: 40% of anomalies are "it's just peak hours" +- Users ignore alerts (alert fatigue) +- Gradual degradation goes undetected: 2% daily memory leak over 7 days looks "normal" +- Seasonal patterns (Black Friday, end-of-quarter) trigger false alarms **Prevention:** -1. **Mark secret fields with struct tags** - `json:"-" yaml:"api_token"` prevents marshaling -2. **Implement String() method for config** - Return redacted version for logging -3. **Log config validation only** - Log "token present: yes" not token value -4. **Add linter rule** - Detect `log.*config` patterns in code review -5. **Sanitize error messages** - Wrap API errors, strip credentials from strings -6. **Log audit** - Search existing logs for exposed tokens before production +1. **Time-of-day matching** — Compare current value to same time-of-day in previous 7 days: + - Current: Monday 10:15am + - Baseline: Average of [last Monday 10:15am, 2 Mondays ago 10:15am, ...] + - Use 1-hour window around target time to handle small time shifts -**Detection:** -- Warning sign: Log entries contain "token=" or "api_key=" followed by values -- Test: Grep application logs for known test secret values -- Test: Log config object, verify secrets are redacted - -**References:** -- [Kubernetes Secrets Management Best Practices](https://www.cncf.io/blog/2023/09/28/kubernetes-security-best-practices-for-kubernetes-secrets-management/) -- [Kubernetes Secrets: Best Practices](https://blog.gitguardian.com/how-to-handle-secrets-in-kubernetes/) - -**Which phase:** -Phase 2 (Logz.io API Client) - Establish logging patterns before building MCP tools - ---- +2. **Minimum deviation threshold** — Only flag as anomaly if: + - Absolute deviation: `|current - baseline| > threshold` (e.g., 1000 requests/sec) + - AND relative deviation: `|(current - baseline) / baseline| > percentage` (e.g., 50%) + - This prevents "CPU is 0.1% higher!" false positives -## Moderate Pitfalls - -Mistakes that cause delays, technical debt, or intermittent issues. - -### Pitfall 7: Rate Limit Handling Without Exponential Backoff +3. **Baseline staleness detection** — If baseline data is >14 days old or has gaps, warn "insufficient data for anomaly detection" instead of showing false confidence. -**What goes wrong:** -Logz.io enforces 100 concurrent requests per account. Without exponential backoff, multiple MCP tools hitting rate limit will retry immediately, amplifying the problem. Fixed-delay retries create thundering herd when rate limit resets. +4. **Trend analysis (future enhancement)** — Detect monotonic increase/decrease over 7 days using linear regression. If slope is significant, flag "trending up" instead of "anomaly." -**Why it happens:** -Rate limiting is account-wide, not per-instance. Multiple users running Claude Code simultaneously share the same rate limit. Naive retry logic uses fixed delays or immediate retries. HTTP 429 responses don't include Retry-After header (not documented). +5. **Manual thresholds** — Allow users to set expected ranges per metric in dashboard tags (e.g., `threshold:cpu_90%`). Use as override for ML-based detection. -**Consequences:** -- Request storms during rate limit periods -- Degraded service for all users sharing account -- MCP tools time out waiting for responses -- Support tickets for "integration randomly fails" - -**Prevention:** -1. **Implement exponential backoff with jitter** - Start at 1s, double each retry, max 32s -2. **Track rate limit globally per instance** - Share state across tool invocations -3. **Fail fast after 3 retries** - Return clear error to user, don't hang -4. **Add rate limit metrics** - Expose `logzio_rate_limit_hits_total` counter -5. **Document concurrent request limit** in integration configuration -6. **Consider request queuing** - Serialize requests to stay under limit +6. **STL decomposition (advanced)** — For high-confidence metrics, use Seasonal-Trend decomposition (Loess) to separate trend, seasonality, and residuals.

Aggregation happens implicitly when grouping by fields. Project context mentions both limits but doesn't explain which queries use which. Easy to hit wrong limit during development. - -**Consequences:** -- Pattern mining tool silently truncates results at 1,000 (uses aggregation) -- Raw logs tool works fine (non-aggregated, 10,000 limit) -- Inconsistent behavior across MCP tools confuses users -- Testing with small datasets misses the problem - -**Prevention:** -1. **Document which MCP tools hit which limit** in tool descriptions -2. **Validate limit parameter against query type** - Reject invalid combinations early -3. **Warn user when approaching limit** - "Returning 1,000 of 50,000 matching logs" -4. **Use scroll API for large result sets** - Avoid hitting limits entirely -5. **Test with large datasets** - Ensure limits are enforced correctly - -**Detection:** -- Warning sign: Tool returns exactly 1,000 or 10,000 results (suspicious) -- Test: Query returning >1,000 aggregated results, verify error handling - -**References:** -- Project context: "Result limits: 1,000 aggregated, 10,000 non-aggregated" -- [Elasticsearch Query DSL Guide](https://logz.io/blog/elasticsearch-queries/) +## Moderate Pitfalls -**Which phase:** -Phase 3 (MCP Tool Implementation) - Query construction and result handling +Mistakes that cause delays or technical debt. --- -### Pitfall 9: Analyzed Field Sorting/Aggregation Failure +### Pitfall 6: Grafana Variable Interpolation Edge Cases -**What goes wrong:** -Elasticsearch analyzed fields (like `message`) are tokenized for full-text search. You cannot sort or aggregate on them. MCP tool tries `"sort": [{"message": "asc"}]` and gets cryptic error about "fielddata disabled on text fields." +**What goes wrong:** Grafana template variables have multiple syntaxes (`$var` vs `[[var]]`) and formatting options (`${var:csv}`, `${var:regex}`). Multi-value variables interpolate differently per data source (Prometheus uses regex, InfluxDB uses OR clauses). Custom "All" values (`*` vs concatenated values) break when used incorrectly. -**Why it happens:** -Field mapping determines whether field is analyzed (full-text) or keyword (exact match). Logz.io auto-maps many fields, but behavior may differ from self-hosted Elasticsearch. Sorting/aggregation requires keyword fields. Error messages are Elasticsearch internals, not user-friendly. +**Why it happens:** Variable interpolation happens at Grafana query time, not dashboard storage time. Different data sources have different query languages, so Grafana transforms variables differently. The `[[var]]` syntax is deprecated but still appears in old dashboards. **Consequences:** -- MCP tools fail with confusing errors -- Query construction logic becomes brittle (needs field mapping knowledge) -- Different behavior between environments (mapping differences) +- Query stored as `{job=~"$job"}` but when executed with multi-select, becomes `{job=~"(api|web)"` (correct) or `{job=~"api,web"}` (broken regex) +- Custom "All" value of `.*` works for Prometheus but breaks for exact-match databases +- Variable extraction from PromQL during parsing returns `$job` instead of actual values, breaking service inference **Prevention:** -1. **Fetch field mappings during integration Start()** - Cache them -2. **Validate sort/aggregation fields against mappings** - Only allow keyword fields -3. **Provide user-friendly error** - "Cannot sort on 'message' (text field). Use 'message.keyword' instead." -4. **Document common field suffixes** - `.keyword` for exact match, base field for search -5. **Add field mapping explorer tool** - Let users discover available fields +1. **Store variables separately** — Extract dashboard `templating.list` into separate Variable nodes in graph: `{name: "job", type: "query", multi: true, includeAll: true}` +2. **Do NOT interpolate during ingestion** — Keep queries as-is with `$var` placeholders. Grafana API handles interpolation during query execution. +3. **Pass variables to Grafana API** — When querying metrics, include `scopedVars` in `/api/ds/query` request body with AI-provided values. +4. **Document variable types** — In graph schema, classify variables: + - **Scoping** (namespace, cluster, region): AI provides per MCP call + - **Entity** (pod, service): Used for drill-down + - **Detail** (time range, aggregation): Controls visualization + +5. **Test multi-value variables** — Create fixture dashboard with `job` variable set to multi-select.

If you watch many integration config files (or watch a directory with many files), you hit the OS limit (default 256) and get "too many open files" error. +**What goes wrong:** Grafana Cloud API has rate limits (600 requests/hour for access policies). Large organizations with hundreds of dashboards hit limits during initial ingestion. Grafana API lacks pagination for dashboard list endpoints (default max 5000 data sources, no explicit dashboard limit documented). -**Why it happens:** -macOS kqueue is more resource-intensive than Linux inotify. The existing integration watcher watches a single file, but if deployment pattern involves watching multiple config files (one per integration instance), the problem scales. This is a platform-specific behavior. +**Why it happens:** Grafana API evolved for interactive use (humans clicking UI) not bulk automation. Rate limits prevent API abuse but block legitimate batch operations like "ingest all dashboards." **Consequences:** -- Watcher fails to start on macOS (development machines) -- Error is cryptic ("too many open files" doesn't mention fsnotify) -- Works fine on Linux (CI/production), fails on developer laptops -- Blocks local testing of multi-instance scenarios +- Initial ingestion of 200 dashboards × 5 panels × 3 queries = 3000 API calls, hits rate limit +- Dashboard list returns first 5000 results, silently truncates rest +- Concurrent dashboard ingestion from multiple Spectre instances triggers rate limit **Prevention:** -1. **Watch parent directory, not individual files** - Single file descriptor for entire directory -2. **Filter events by filename** - Ignore irrelevant files in directory -3. **Document macOS ulimit requirement** - `ulimit -n 4096` in setup docs -4. **Add startup check** - Verify file descriptor limit is sufficient -5. **Log clear error** - "fsnotify failed: increase file descriptor limit (ulimit -n 4096)" +1. **Batch dashboard fetching** — Use `/api/search` endpoint with `type=dash-db` to list all dashboards, then fetch each full dashboard via `/api/dashboards/uid/:uid`. Do NOT fetch via `/api/dashboards/db/:slug` (deprecated). +2. **Rate limit backoff** — Detect 429 Too Many Requests response. Implement exponential backoff: wait 60s, then 120s, then 240s. Log "rate limited, retrying..." to UI. +3. **Incremental ingestion** — On first run, ingest dashboards tagged `overview` only (typically <20). Full ingestion happens in background with rate limiting. +4. **Cache dashboard JSON** — After initial fetch, only re-fetch if dashboard `version` changed (check via lightweight `/api/search` which includes version field). +5. **Pagination detection** — Check if dashboard list length equals suspected page size (e.g., 1000, 5000).

During rotation, there's a window where application has old secret cached but it's already invalid. Requests fail with 401 errors until hot-reload completes. +**What goes wrong:** Dashboard panel layout uses `gridPos` with coordinates `{x, y, w, h}` where the grid has "negative gravity" — panels automatically move upward to fill gaps. When programmatically modifying layouts or calculating panel importance, Y-coordinate alone doesn't indicate visual hierarchy. -**Why it happens:** -Simple rotation (generate new → invalidate old) assumes instant propagation. File-based hot-reload takes time (fsnotify event → reload → HTTP client update). Kubernetes kubelet syncs volumes every 60s by default. Secret provider may not support overlapping active versions. +**Why it happens:** Grafana UI auto-arranges panels to eliminate whitespace. When a panel is deleted, panels below move up. The stored `gridPos.y` reflects final position after gravity, not intended hierarchy. **Consequences:** -- Downtime during secret rotation (seconds to minutes) -- 401 errors visible to users during rotation window -- Rotation becomes risky, teams avoid doing it regularly -- Security posture degrades (stale secrets stay active) +- Importance ranking "first panel is overview" breaks when top panel is full-width (y=0) but second panel also has y=0 (placed to the right, not below) +- Panel reconstruction from graph fails to maintain visual layout +- Drill-down relationships inferred from position are incorrect: "panel at y=5 drills into panel at y=10" but they're actually side-by-side **Prevention:** -1. **Use dual-phase rotation** - Generate new, wait for propagation, invalidate old -2. **Support multiple active tokens** - Application accepts both old and new during transition -3. **Implement grace period** - Keep old secret valid for 5 minutes after new one deployed -4. **Monitor rotation health** - Alert if 401 errors spike during rotation -5. **Document rotation procedure** - Step-by-step with verification checkpoints -6. **Test rotation in staging** - Verify zero-downtime before production +1. **Sort by y then x** — When ranking panels by importance: sort by `gridPos.y` ascending, then `gridPos.x` ascending. This gives reading order (left-to-right, top-to-bottom). +2. **Use panel type as signal** — "Row" panels (type: "row") group related panels. Panel immediately after a row is child of that row. +3. **Rely on dashboard tags** — Use Grafana tags or dashboard JSON `tags` field for explicit hierarchy (`overview`, `detail`), not inferred from layout. +4. **Store original gridPos** — When saving to graph, preserve exact `gridPos` for reconstruction. Do NOT recalculate positions. **Detection:** -- Warning sign: 401 errors during known rotation windows -- Test: Rotate secret while load testing, verify no 401s +- Panel importance ranking shows "graph" panel before "singlestat" panel when visual hierarchy is opposite +- Dashboard reconstruction places panels in wrong positions +- Drill-down links go to unrelated panels -**References:** -- [Zero Downtime Secrets Rotation: 10-Step Guide](https://www.doppler.com/blog/10-step-secrets-rotation-guide) -- [AWS: Rotate database credentials without restarting containers](https://docs.aws.amazon.com/prescriptive-guidance/latest/patterns/rotate-database-credentials-without-restarting-containers.html) -- [Secrets rotation strategies for long-lived services](https://technori.com/news/secrets-rotation-long-lived-services/) +**Affected phases:** Phase 2 (graph schema), Phase 5 (dashboard hierarchy inference) -**Which phase:** -Phase 2 (Logz.io API Client) - Client initialization and credential refresh logic +**References:** +- [Dashboard JSON Model](https://grafana.com/docs/grafana/latest/visualizations/dashboards/build-dashboards/view-dashboard-json-model/) +- [Dashboard JSON Structure](https://yasoobhaider.medium.com/using-grafana-json-model-howto-509aca3cf9a9) --- -## Minor Pitfalls - -Mistakes that cause inconvenience but are easily fixable. - -### Pitfall 12: Time Range Default Confusion (Seconds vs Milliseconds) +### Pitfall 9: PromQL Label Cardinality Mistakes -**What goes wrong:** -Logz.io API accepts Unix timestamps in milliseconds. Developer defaults to Go's `time.Now().Unix()` (seconds), queries return no results. Error is silent (valid query, just wrong time range). +**What goes wrong:** Developers add high-cardinality labels to metrics (`user_id`, `request_id`, `trace_id`) causing millions of time series. Queries like `rate(http_requests{trace_id=~".*"}[5m])` timeout or OOM. Service inference from labels fails when label values are unbounded. -**Why it happens:** -Go standard library uses seconds for Unix timestamps. JavaScript uses milliseconds. Elasticsearch can accept both but prefers milliseconds. Easy to forget conversion. Project context doesn't specify which format to use. +**Why it happens:** Prometheus best practices warn against high cardinality but Grafana dashboards may query external systems (Thanos, Mimir) with poor label hygiene. Every unique label combination creates a new time series in memory. **Consequences:** -- MCP tools return empty results for valid queries -- Confusing user experience ("I know there are logs in that timeframe") -- Hard to debug (no error, just wrong results) +- Queries timeout after 30 seconds +- Prometheus memory usage spikes to 10GB+ for simple `rate()` query +- Service inference extracts 100K "services" from `trace_id` label instead of 10 services from `job` label +- Grafana API returns partial results or errors **Prevention:** -1. **Use milliseconds consistently** - Convert at input boundary -2. **Add unit tests** - Verify timestamp format in queries -3. **Validate time ranges** - Reject timestamps in the future or too far past -4. **Log effective time range** - "Querying logs from 2024-01-20T10:00:00Z to 2024-01-20T11:00:00Z" -5. **Accept both formats, normalize internally** - Check magnitude, convert if needed +1. **Label validation during ingestion** — When parsing PromQL, extract label matchers. If label name matches high-cardinality patterns (`*_id`, `trace_*`, `span_*`, `uuid`, `session`), log warning: "High-cardinality label detected in dashboard '{dashboard}', panel '{panel}'" +2. **Service inference whitelist** — Only infer services from known-good labels: `job`, `service`, `app`, `application`, `namespace`, `cluster`. Ignore all other labels. +3. **Query timeout enforcement** — Set Grafana query timeout to 30s (via `/api/ds/query` request). If query times out, show "query too slow" instead of crashing. +4. **Pre-aggregation hints** — Detect queries missing aggregation: `http_requests_total` without `sum()` or `rate()`. Log warning "query may return too many series." **Detection:** -- Warning sign: Queries return 0 results when logs exist -- Test: Query with known log entry timestamp, verify it's found +- Grafana queries return 429 "too many series" errors +- Service node count in graph is >1000 (should be <100 for typical setup) +- Query execution logs show "timeout" or "OOM" -**References:** -- [Logz.io Search API](https://api-docs.logz.io/docs/logz/search/) +**Affected phases:** Phase 3 (PromQL parsing), Phase 5 (service inference), Phase 7 (anomaly detection queries) -**Which phase:** -Phase 3 (MCP Tool Implementation) - Time range parameter handling +**References:** +- [3 Common Mistakes with PromQL](https://home.robusta.dev/blog/3-common-mistakes-with-promql-and-kubernetes-metrics) +- [PromQL Best Practices](https://last9.io/blog/promql-cheat-sheet/) --- -### Pitfall 13: Integration Name Used Directly in Tool Names +### Pitfall 10: Progressive Disclosure State Leakage -**What goes wrong:** -If integration name contains spaces or special characters (e.g., "Logz.io Production"), tool name becomes `logzio_Logz.io Production_overview` (invalid MCP tool name). Registration fails. +**What goes wrong:** Progressive disclosure (overview → aggregated → details) requires maintaining context across MCP tool calls. If state is stored server-side (e.g., "user selected cluster X in overview, now calling aggregated"), concurrent AI sessions interfere. If state is AI-managed, AI forgets context and calls details tool without scoping variables. -**Why it happens:** -The existing VictoriaLogs integration uses name directly in tool name construction: `fmt.Sprintf("victorialogs_%s_overview", v.name)`. Assumes name is kebab-case or snake_case. No validation of integration name format. +**Why it happens:** Spectre follows stateless MCP architecture (per PROJECT.md: "AI passes filters per call, no server-side session state"). But progressive disclosure implies stateful flow: overview picks service → aggregated shows correlations → details expands dashboard. **Consequences:** -- Tool registration fails silently or with cryptic error -- Integration starts but MCP tools don't work -- Hard to debug (error is far from name definition) +- AI calls `metrics_aggregated` without cluster/namespace, returns aggregated results across ALL clusters (too broad, slow) +- Concurrent Claude sessions: User A selects "prod" cluster, User B selects "staging", both get same results (state collision) +- AI forgets to pass scoping variables from overview to details: "show me details for service X" but doesn't include `cluster=prod` from previous call **Prevention:** -1. **Sanitize name for tool construction** - Replace spaces with underscores, lowercase -2. **Validate name at config load** - Reject names with special characters -3. **Document name format requirement** - "Name must be lowercase alphanumeric with hyphens" -4. **Add test case** - Verify tool registration with various name formats -5. **Log generated tool names** - Make it visible what names were registered +1. **Stateless MCP tools** — Already implemented. Each tool call is independent, all filters passed as parameters. +2. **AI context management** — Document in MCP tool descriptions: "To drill down, copy scoping variables (cluster, namespace, service) from overview response and pass to aggregated/details calls." +3. **Require scoping variables** — Make `cluster` or `namespace` a required parameter for `metrics_aggregated` and `metrics_details` tools. Return error if missing. +4. **Prompt engineering** — MCP tool response includes reminder: "To see details for service 'api', call metrics_details with cluster='prod', namespace='default', service='api'." +5. **Test multi-turn conversations** — E2E test: AI calls overview → picks service → calls aggregated with correct scoping → calls details. Verify no state leakage. **Detection:** -- Warning sign: Integration starts but `mcp tools list` doesn't show expected tools -- Test: Configure integration with name containing spaces, verify error or sanitization +- AI calls `metrics_details` without scoping, returns "too many results" or timeout +- Multiple AI sessions report unexpected results (sign of shared state) +- Logs show tool calls with missing required parameters -**References:** -- Existing code: `/home/moritz/dev/spectre-via-ssh/internal/integration/victorialogs/victorialogs.go` line 163 +**Affected phases:** Phase 6 (MCP tool design), Phase 8 (UI integration) -**Which phase:** -Phase 3 (MCP Tool Implementation) - Tool registration logic +**References:** +- [Progressive Disclosure NN/G](https://www.nngroup.com/articles/progressive-disclosure/) +- [Progressive Disclosure Pitfalls](https://userpilot.com/blog/progressive-disclosure-examples/) +- [B2B SaaS UX 2026](https://www.onething.design/post/b2b-saas-ux-design) --- -### Pitfall 14: Debounce Too Short for Kubernetes Secret Updates - -**What goes wrong:** -Integration watcher uses 500ms debounce (existing code line 59). Kubernetes Secret volume updates trigger multiple events (Remove → Create → Write) within 1 second as kubelet syncs. Reload triggers multiple times, causing unnecessary restarts. - -**Why it happens:** -Kubelet sync isn't atomic from fsnotify's perspective. Atomic writer updates symlink, then rewrites target file. 500ms debounce is tuned for editor saves (many fast events), not Kubernetes volume updates (slower but still multiple events). - -**Consequences:** -- Secret reload triggers 2-3 times for single update -- Unnecessary churn in HTTP client reconnection -- Metrics show inflated reload counts -- Log noise - -**Prevention:** -1. **Increase debounce to 2 seconds** for Kubernetes environments -2. **Make debounce configurable** - Different values for dev (editor) vs prod (K8s) -3. **Add reload deduplication** - Track content hash, skip if unchanged -4. **Log debounce behavior** - "Received 3 events, coalesced into 1 reload" -5. **Test with real Kubernetes Secret updates** - Not just local file edits - -**Detection:** -- Warning sign: Multiple reload log entries within seconds -- Test: Update secret once, verify exactly one reload (after debounce period) - -**References:** -- Existing code: `/home/moritz/dev/spectre-via-ssh/internal/config/integration_watcher.go` line 59 -- [fsnotify Issue #372](https://github.com/fsnotify/fsnotify/issues/372) +## Minor Pitfalls -**Which phase:** -Phase 2 (Logz.io API Client) - Watcher configuration tuning +Mistakes that cause annoyance but are fixable. --- -### Pitfall 15: No Index Specification (Defaults May Surprise) +### Pitfall 11: Dashboard JSON Comment and Whitespace Loss -**What goes wrong:** -Logz.io search API documentation says "two consecutive indexes only (today + yesterday default)." If user expects to query logs from 3 days ago, they get empty results. API silently ignores logs outside the default index range. +**What goes wrong:** Dashboard JSON may include comments (via `__comment` fields) or custom formatting (indentation, field ordering). When parsing dashboard → storing in graph → reconstructing JSON, comments and formatting are lost. -**Why it happens:** -Elasticsearch uses date-based index rotation. Logz.io default is recent 2 days for performance. Querying older logs requires explicit index specification. This is mentioned in project context but not enforced in API client. +**Why it happens:** JSON parsers discard comments and reformat. Grafana dashboard export uses custom field ordering (e.g., `id` before `title`) but Go `json.Marshal` uses alphabetical order. **Consequences:** -- Historical log queries return incomplete results -- Users don't understand why old logs aren't visible -- Workaround (specify indexes) is not discoverable +- Users export dashboard from Spectre, lose original comments and formatting +- Git diffs show entire file changed even when only one panel modified (due to field reordering) +- Minor annoyance, not functionality break **Prevention:** -1. **Validate time range against index coverage** - Warn if querying >2 days -2. **Auto-calculate index names from time range** - `logzio-YYYY-MM-DD` pattern -3. **Document index limitation prominently** - In MCP tool descriptions -4. **Add index parameter to MCP tools** - Advanced users can override -5. **Log effective index range** - "Querying indexes: logzio-2024-01-20, logzio-2024-01-21" +1. **Store raw JSON** — Always preserve original dashboard JSON in graph or database. When exporting, return raw JSON instead of reconstructed. +2. **Do NOT reconstruct JSON** — Parsing is for graph population only, not for round-trip export. +3. **Document limitation** — If export is needed, add note: "Exported dashboards may have different formatting than original." **Detection:** -- Warning sign: Historical queries (>2 days ago) return 0 results -- Test: Query with 3-day-old timestamp, verify warning or index specification +- User reports "exported dashboard lost my comments" +- Git diff shows reformatted JSON -**References:** -- Project context: "Two consecutive indexes only (today + yesterday default)" -- [Logz.io Search API](https://api-docs.logz.io/docs/logz/search/) +**Affected phases:** Phase 2 (dashboard storage) -**Which phase:** -Phase 3 (MCP Tool Implementation) - Query construction with index awareness +**References:** +- [PromQL Parser C# Limitations](https://github.com/djluck/PromQL.Parser) --- -## Secret Management Pitfalls - -Security-specific issues to avoid. - -### Pitfall 16: Secret Leakage in Error Messages +### Pitfall 12: Histogram Quantile Misuse -**What goes wrong:** -HTTP client error includes full request details: `GET https://api.logz.io/logs?X-API-TOKEN=abc123...`. Error is logged, bubbles up to MCP tool response, ends up in Claude Code conversation history. +**What goes wrong:** Developers use `histogram_quantile()` on already-aggregated data or forget `le` label, producing nonsensical results. Example: `histogram_quantile(0.95, rate(http_duration_bucket[5m]))` without `sum() by (le)`. -**Why it happens:** -Standard HTTP libraries include full request in errors for debugging. Headers contain credentials. Error wrapping preserves original error. No sanitization layer between HTTP client and caller. +**Why it happens:** Histogram metrics require specific aggregation patterns. Prometheus histograms use `_bucket` suffix with `le` (less than or equal) labels. Incorrect aggregation loses bucket boundaries. **Consequences:** -- API token visible in application logs -- Token visible in MCP tool error responses -- Token may be transmitted to Anthropic via Claude Code (conversation history) -- Credential rotation required if leak detected +- 95th percentile shows 0.0 or NaN +- Anomaly detection on latency percentiles fails **Prevention:** -1. **Implement HTTP client error wrapper** - Strip `X-API-TOKEN` header from errors -2. **Redact credentials in request logs** - `X-API-TOKEN: [REDACTED]` -3. **Never log full HTTP requests** - Log method + path only, not headers -4. **Sanitize errors before MCP response** - Generic "authentication failed" message -5. **Add security test** - Simulate auth failure, verify token not in error +1. **Template detection** — When parsing PromQL, detect `histogram_quantile()`. Verify it wraps `sum(...) by (le)` or `rate(...[...]) by (le)`. Log warning if missing. +2. **Documentation** — When displaying histogram metrics in MCP tools, show note: "Percentile calculated from histogram buckets." **Detection:** -- Warning sign: Grep logs for "X-API-TOKEN" finds matches -- Test: Trigger auth error, verify token not in error message +- PromQL contains `histogram_quantile` without `by (le)` +- Query returns NaN or 0 for percentile metrics -**References:** -- [Kubernetes Secrets Management Best Practices](https://www.cncf.io/blog/2023/09/28/kubernetes-security-best-practices-for-kubernetes-secrets-management/) +**Affected phases:** Phase 3 (PromQL parsing validation) -**Which phase:** -Phase 2 (Logz.io API Client) - HTTP client error handling +**References:** +- [PromQL Tutorial: Histograms](https://coralogix.com/blog/promql-tutorial-5-tricks-to-become-a-prometheus-god/) +- [PromQL Cheat Sheet](https://promlabs.com/promql-cheat-sheet/) --- -### Pitfall 17: Base64 Encoding Is Not Encryption +### Pitfall 13: Absent Metric False Positives -**What goes wrong:** -Kubernetes Secrets are base64-encoded, not encrypted. Developer assumes this provides security, stores API token in Secret without enabling encryption-at-rest in etcd. Anyone with etcd access can decode secrets. +**What goes wrong:** Anomaly detection flags "metric missing" when metric is legitimately zero (e.g., `error_count=0` during healthy period). Using `absent()` function detects truly missing metrics but doesn't distinguish from zero values. -**Why it happens:** -Base64 looks like encryption (random characters). Kubernetes documentation mentions "Secrets" which implies security. Encryption-at-rest is not enabled by default. This is a Kubernetes platform issue, but affects integration security. +**Why it happens:** Prometheus doesn't store zero-value counters. If `http_errors_total` has no errors, the metric doesn't exist in TSDB. `absent(metric)` returns 1 (true) both when metric never existed and when it's currently zero. **Consequences:** -- Secrets vulnerable to etcd compromise -- Compliance violations (secrets stored in plaintext) -- Cluster-wide security issue (affects all secrets) +- Alert fatigue: "error_count missing!" every time there are no errors +- Cannot distinguish "scrape failed" from "no errors" **Prevention:** -1. **Document encryption-at-rest requirement** - In deployment docs -2. **Recommend External Secrets Operator** - Fetch from Vault/AWS Secrets Manager -3. **Verify encryption during setup** - Check etcd encryption config -4. **Use least-privilege RBAC** - Limit who can read Secrets -5. **Consider sealed secrets** - Encrypt before committing to Git +1. **Check scrape status first** — Query `up{job="..."}` metric. If 0, scrape failed. If 1 but metric missing, it's legitimately zero. +2. **Use `or vector(0)`** — PromQL pattern: `metric_name or vector(0)` returns 0 when metric absent. +3. **Baseline staleness** — Only flag missing if metric existed in previous 7 days. New services won't trigger false alerts. **Detection:** -- Check: `kubectl describe secret` shows base64 data (not encrypted) -- Check: etcd encryption provider config exists -- Audit: Review who has `get secrets` RBAC permission +- Anomaly alerts during healthy periods: "error rate missing" +- `absent()` queries return 1 constantly -**References:** -- [Kubernetes Secrets Good Practices](https://kubernetes.io/docs/concepts/security/secrets-good-practices/) -- [Kubernetes Secrets Management Limitations](https://www.groundcover.com/blog/kubernetes-secret-management) +**Affected phases:** Phase 7 (anomaly detection) -**Which phase:** -Phase 1 (Planning & Research) - Security architecture decision, documented before implementation +**References:** +- [PromQL Tricks: Absent](https://last9.io/blog/promql-tricks-you-should-know/) --- -### Pitfall 18: Secret Rotation Without Monitoring - -**What goes wrong:** -Secret is rotated (new token deployed), but no monitoring verifies that rotation succeeded. Old token expired, new token has typo, all API calls fail silently until next health check (could be minutes). - -**Why it happens:** -Rotation is treated as deployment task, not operational concern. No metrics track rotation events. Health checks run infrequently (default 30s-60s). Gap between rotation and detection creates downtime. - -**Consequences:** -- Undetected authentication failures during rotation -- Users experience intermittent errors -- Difficult to correlate errors with rotation events - -**Prevention:** -1. **Add rotation event metric** - `logzio_secret_reload_total{status="success|failure"}` -2. **Trigger health check immediately after reload** - Don't wait for next periodic check -3. **Alert on reload failures** - Prometheus alert: `rate(logzio_secret_reload_total{status="failure"}) > 0` -4. **Log before/after token prefix** - "Reloaded token: old=abc123..., new=def456..."

The primary use case is VictoriaLogs integration with intelligent log exploration using template mining and progressive disclosure UX patterns. +The v1.3 Grafana Metrics Integration extends Spectre's progressive disclosure pattern from logs to metrics. Research recommends using custom HTTP client for Grafana API (official clients are immature), Prometheus official PromQL parser for metric extraction, existing FalkorDB patterns for graph storage, and custom statistical baseline for anomaly detection. This approach prioritizes production-ready libraries, avoids dependency bloat, and aligns with Spectre's existing architecture (FalkorDB integration, plugin system, MCP tools). -Expert systems build extensible observability platforms using compile-time plugin registration (not runtime .so loading) with RPC-based process isolation. The recommended approach uses HashiCorp go-plugin for plugin lifecycle, Koanf for hot-reload configuration management, and Drain algorithm for log template mining. Critical architecture decisions include: interface-based plugin registry (avoiding Go stdlib plugin versioning hell), pipeline stages with bounded channels for backpressure, and atomic pointer swap for race-free config reloads. +The key architectural insight is to parse PromQL at ingestion time (not query time) to build a semantic graph of Dashboard→Panel→Query→Metric→Service relationships. This enables intelligent queries like "show me all dashboards tracking pod memory" without re-parsing queries. The progressive disclosure model (overview→aggregated→details) mirrors the proven log exploration pattern and provides AI-driven anomaly detection with severity ranking as a competitive differentiator. -The primary risk is template mining instability with variable-starting logs, which causes template explosion and degrades accuracy from 90% to under 70%. Mitigation requires pre-tokenization with masking, periodic template rebalancing, and monitoring template growth metrics. Secondary risks include config hot-reload race conditions (prevented via atomic.Value) and progressive disclosure state loss (prevented via URL-based state). All critical risks have proven mitigation strategies from production deployments. +Critical risks include Grafana API version breaking changes (mitigated by storing raw dashboard JSON and defensive parsing), service account token scope confusion (mitigated by separate auth paths for Cloud vs self-hosted), and graph schema cardinality explosion (mitigated by storing structure only, not time-series data). The recommended approach avoids handwritten PromQL parsing (use official library), prevents variable interpolation edge cases (store separately, pass to API), and handles baseline drift with time-of-day matching for seasonality. ## Key Findings ### Recommended Stack -Research identified battle-tested technologies for plugin systems and log processing, avoiding common pitfalls like Go stdlib plugin versioning constraints and Viper's case-sensitivity bugs. +The technology stack prioritizes production-ready libraries with active maintenance, compatibility with Go 1.24+, and alignment with Spectre's existing patterns. No external services are required beyond Grafana API access and the already-deployed FalkorDB instance. **Core technologies:** -- **HashiCorp go-plugin v1.7.0**: RPC-based plugin architecture — avoids stdlib plugin versioning hell, provides process isolation, production-proven in Terraform/Vault/Nomad -- **Koanf v2.3.0**: Hot-reload configuration management — modular design, built-in file watching, fixes Viper's case-insensitivity and bloat issues -- **LoggingDrain (Drain algorithm)**: Log template mining — O(log n) matching, handles high-volume streams, sub-microsecond performance -- **net/http (stdlib)**: VictoriaLogs client — sufficient for simple HTTP API, no custom client needed -- **Existing stack reuse**: mark3labs/mcp-go for MCP server, connectrpc for REST API, gopkg.in/yaml.v3 for config +- **Custom HTTP client (net/http)**: Grafana API access — official Go clients are deprecated or immature; custom client provides production control and matches existing integration patterns (VictoriaLogs, Logz.io) +- **prometheus/promql/parser**: PromQL parsing — official Prometheus library, production-proven, 556+ dependents; avoids handwritten parser complexity +- **FalkorDB (existing v2.0.2)**: Graph storage — already integrated; reuse existing patterns for Dashboard→Panel→Query→Metric relationships +- **Custom statistical baseline (stdlib math)**: Anomaly detection — z-score with time-of-day matching; simple, effective, no dependencies; defers ML complexity to future versions +- **SecretWatcher (existing pattern)**: Token management — Kubernetes-native hot-reload for Grafana API tokens; proven pattern from VictoriaLogs/Logz.io -**Stack confidence:** HIGH overall. Only MEDIUM component is LoggingDrain library (small community), but Drain algorithm itself is HIGH confidence (proven in academic research and IBM production systems). Mitigation: algorithm is simple enough to re-implement in 200-300 LOC if library proves buggy. +**New dependencies needed:** +```bash +go get github.com/prometheus/prometheus/promql/parser@latest +``` + +All other components use stdlib (net/http, encoding/json, math, time) or existing dependencies. ### Expected Features -Research revealed MCP ecosystem favors minimalist tool design (10-20 tools maximum) due to context window constraints, directly influencing how plugins expose functionality and how log exploration should be surfaced. +Research divides features into four categories: table stakes (users expect this), differentiators (competitive advantage), anti-features (explicitly avoid), and phase-specific (builds on foundation). **Must have (table stakes):** -- Plugin discovery and lifecycle (load/unload with error isolation) -- Semantic versioning with compatibility checking -- Full-text log search with time range and field-based filtering -- Basic aggregation (count by time window, group by field, top-N queries) -- Progressive disclosure navigation (overview → aggregated → detail, max 3 levels) -- Clear MCP tool descriptions with JSON Schema inputs -- Breadcrumb navigation with state preservation +- Dashboard execution via API (fetch, parse, execute queries with time ranges) +- Basic variable support (single-value, simple substitution) +- RED method metrics (rate, errors, duration for request-driven services) +- USE method metrics (utilization, saturation, errors for resources) **Should have (competitive differentiators):** -- Automatic log template mining (extract patterns without manual config) -- Category-based tool loading (load tool groups on demand, not all upfront) -- High-cardinality field search (fast search on trace_id despite millions of unique values) -- Smart defaults with SLO-first views -- MCP Resources for context (expose docs/schemas as resources, not tools) +- AI-driven anomaly detection with severity ranking (statistical baseline, z-score, correlation) +- Intelligent variable scoping (classify as scope/entity/detail, auto-set defaults per tool level) +- Cross-signal correlation (metrics↔logs linking via shared namespace/time) +- Progressive disclosure pattern (overview→aggregated→details mirrors log exploration) **Defer (v2+):** -- Novelty detection (time window comparison of patterns — requires baseline period) -- Anomaly scoring (rank logs by unusualness — complex ML implementation) -- Plugin marketplace/registry (centralized discovery — unnecessary for MVP) -- Hot reload without restart (advanced, can iterate to this) -- Network-based plugin discovery (adds deployment complexity without clear demand) +- Advanced variable support (multi-value with pipe syntax, chained variables 3+ levels deep, query variables) +- Sophisticated anomaly detection (ML models, LSTM, adaptive baselines, root cause analysis) +- Trace linking (requires OpenTelemetry adoption) +- Dashboard management (create/edit/provision dashboards) + +**Anti-features (explicitly avoid):** +- Dashboard UI replication (return structured data, not rendered visualizations) +- Custom dashboard creation via API (read-only access, users manage dashboards in Grafana) +- User-specific dashboard management (stateless MCP architecture, no per-user state) +- Full variable dependency resolution (support 2-3 levels, warn on deeper chaining) ### Architecture Approach -The architecture uses interface-based plugin registration (compile-time, not runtime .so loading) with a pipeline processing pattern for log ingestion. Plugins implement a standard interface and register themselves in a compile-time registry. Log processing follows a staged pipeline with bounded channels for backpressure: ingestion → normalization → template mining → structuring → batching → VictoriaLogs storage. +The Grafana integration follows Spectre's existing plugin architecture, extending it with six new components: dashboard sync, PromQL parser, graph storage schema, query executor, anomaly detector, and MCP tools. The design prioritizes incremental sync (only changed dashboards), structured graph queries (semantic relationships), and integration with existing infrastructure (FalkorDB, MCP server, plugin system). **Major components:** -1. **Plugin Manager** (`internal/mcp/plugins/`) — maintains registry of plugins, reads config to enable/disable, handles lifecycle (init/reload/shutdown), registers tools with MCP server -2. **VictoriaLogs Plugin** (`internal/mcp/plugins/victorialogs/`) — implements Plugin interface, manages log processing pipeline, exposes MCP tools for querying, handles template persistence -3. **Log Processing Pipeline** (`pipeline/`) — chain of stages with buffered channels: normalize → mine → structure → batch → write; backpressure via bounded channels with drop-oldest policy -4. **Template Miner** (`miner/`) — Drain algorithm implementation, builds prefix tree by token count and first token, similarity scoring for matches, WAL persistence with snapshots -5. **Configuration Hot-Reload** (`internal/config/watcher.go`) — fsnotify-based file watching, debouncing, SIGHUP signal handling, atomic pointer swap for race-free updates -6. **VictoriaLogs Client** (`client/`) — HTTP wrapper for /insert/jsonline endpoint, NDJSON serialization, retry with backoff, circuit breaker - -**Key patterns to follow:** -- Interface-based plugin registration (not runtime .so loading) -- Pipeline stages with bounded channels (prevents memory exhaustion) -- Drain-inspired template mining (O(log n) matching vs O(n) regex list) -- Atomic pointer swap for config reload (prevents torn reads) -- Template cache with WAL persistence (fast reads, durability across restarts) +1. **GrafanaClient**: HTTP API wrapper for Grafana — handles authentication (Bearer token for Cloud, optional Basic auth for self-hosted), dashboard retrieval, query execution via `/api/ds/query`, rate limiting with exponential backoff +2. **DashboardSyncer**: Ingestion pipeline — incremental sync based on dashboard version, concurrent fetching with worker pool, change detection, batch graph writes in transactions +3. **PromQLParser**: Semantic extraction — uses Prometheus official parser to extract metric names, label selectors, aggregations, functions; stores results in graph for semantic queries +4. **GraphSchema**: Semantic relationships — Dashboard→Panel→Query→Metric→Service edges with CONTAINS, QUERIES, TRACKS relationships; stores structure only (no time-series data, no label values) +5. **QueryService**: Query execution — executes PromQL via Grafana API, formats results for MCP tools, performs graph queries for dashboard discovery ("show dashboards tracking this pod") +6. **AnomalyService**: Statistical detection — computes baselines (7-day history with time-of-day matching), calculates z-scores, classifies severity (info/warning/critical), caches baselines in graph (1-hour TTL) + +**Data flow:** +- Ingestion: Poll Grafana API → parse dashboards → extract PromQL → build graph (Dashboard→Panel→Query→Metric→Service) +- Query: MCP tool → QueryService → Grafana API → format time series +- Anomaly: MCP tool → AnomalyService → compute baseline (cached) → query current → compare → rank by severity + +**Graph schema strategy:** +Store structure (what exists), not data (metric values). Avoid cardinality explosion by creating nodes for Dashboard (dozens), Panel (hundreds), Query (hundreds), Metric template (thousands), Service (dozens) — NOT for individual time series (millions). Query actual metric values on-demand via Grafana API. ### Critical Pitfalls -Research identified five critical pitfalls that cause rewrites or major production issues, plus several moderate pitfalls that cause delays. +Research identified 13 pitfalls ranging from critical (rewrites) to minor (annoyance). Top 5 require explicit mitigation in roadmap phases. -1. **Go Stdlib Plugin Versioning Hell** — Using stdlib `plugin` package creates brittle deployment where plugins crash with version mismatches. All plugins and host must be built with exact same Go toolchain, dependency versions, GOPATH, and build flags. Prevention: Use HashiCorp go-plugin (RPC-based, process isolation, production-proven). +1. **Grafana API version breaking changes** — Dashboard JSON schema evolves between major versions (v11 URL changes, v12 schema format). Prevention: Store raw dashboard JSON before parsing, version detection via `schemaVersion` field, defensive parsing with optional fields, test against multiple Grafana versions (v9-v12 fixtures). -2. **Template Mining Instability with Variable-Starting Logs** — Drain fails when log messages start with variables instead of constants (e.g., "cupsd shutdown succeeded" vs "irqbalance shutdown succeeded" create separate templates instead of one). Causes template explosion, accuracy drops from 90% to <70%. Prevention: Pre-tokenize with masking (replace known variable patterns before feeding to Drain), use Drain3 with built-in masking, monitor template growth metrics. +2. **Service account token scope confusion** — Cloud vs self-hosted have different auth methods (Bearer vs Basic) and permission scopes (service accounts lack Admin API access). Prevention: Detect Cloud via URL pattern, separate auth paths, minimal permissions (`dashboards:read` only), graceful degradation if optional APIs fail, clear error messages mapping 403 to actionable guidance. -3. **Race Conditions in Config Hot-Reload** — Using sync.RWMutex with in-place field updates creates torn reads where goroutines see partial config state (old URL with new API key). Prevention: Use atomic.Value pointer swap pattern — validate entire config, then single atomic swap (readers see old OR new, never partial). +3. **PromQL parser handwritten complexity** — PromQL has no formal grammar, official parser is handwritten with edge cases. Prevention: Use official `prometheus/promql/parser` library (do NOT write custom parser), best-effort extraction (complex expressions may not fully parse), variable interpolation passthrough (preserve `$var`, `[[var]]` as-is), focus on metric name extraction only. -4. **Template Drift Without Rebalancing** — Log formats evolve over time (syntactic drift), causing accuracy degradation and template explosion after 30-60 days. Prevention: Use Drain3 HELP implementation with iterative rebalancing, implement template TTL (expire templates not seen in 30d), monitor templates-per-1000-logs ratio. +4. **Graph schema cardinality explosion** — Creating nodes for every time series (metric × labels) explodes to millions of nodes. Prevention: Store structure only (Dashboard→Panel→Query→Metric template), do NOT create nodes for label values or time-series data, query actual metric values on-demand via Grafana API, limit to dozens of Dashboards/Services, hundreds of Panels/Queries, thousands of Metric templates. -5. **UI State Loss During Progressive Disclosure** — Component-local state resets on navigation, browser back button doesn't restore context. Prevention: Encode state in URL query params from day 1 (hard to retrofit), use React Router with location.state, implement breadcrumb navigation with clickable links. +5. **Anomaly detection baseline drift** — Simple rolling average ignores seasonality (weekday vs weekend) and concept drift (deployments change baseline). Prevention: Time-of-day matching (compare Monday 10am to previous Mondays at 10am), minimum deviation thresholds (absolute + relative), baseline staleness detection (warn if >14 days old), trend analysis for gradual degradation. -**Moderate pitfalls:** -- MCP protocol version mismatch without graceful degradation (support multiple protocol versions) -- Cross-client template inconsistency (canonical storage in MCP server, deterministic IDs) -- VictoriaLogs live tailing without rate limiting (minimum 1s refresh, warn at >1K logs/sec) -- No config validation before hot-reload (validate and health-check before swap) +**Additional key pitfalls:** +- **Variable interpolation edge cases**: Multi-value variables use different formats per data source (`{job=~"(api|web)"}` for Prometheus). Store variables separately, do NOT interpolate during ingestion, pass to Grafana API during query. +- **Rate limiting**: Grafana Cloud has 600 requests/hour limit. Implement exponential backoff on 429, incremental ingestion (overview dashboards first), cache dashboard JSON, background sync. +- **Progressive disclosure state leakage**: Stateless MCP tools prevent concurrent session interference. Require scoping variables (cluster, namespace), AI manages context across calls, document drill-down pattern in tool descriptions. ## Implications for Roadmap -Based on research, suggested phase structure follows dependency order identified in architecture patterns: plugin foundation must exist before integrations, log processing depends on VictoriaLogs client, template mining can be iterative, UI comes last. +Based on research, v1.3 should follow a 5-phase structure that builds incrementally from foundation (HTTP client, graph schema) through ingestion (PromQL parsing, dashboard sync) to value delivery (MCP tools, anomaly detection). Each phase addresses specific features from FEATURES.md and mitigates pitfalls from PITFALLS.md. -### Phase 1: Plugin Infrastructure Foundation -**Rationale:** Plugin architecture is the foundation for all integrations. Must be correct from day 1 because changing plugin system later (e.g., stdlib plugin to go-plugin) forces complete rewrite. +### Phase 1: Foundation — Grafana API Client & Graph Schema +**Rationale:** Establish HTTP client and graph structure before ingestion logic. Grafana client handles auth complexity (Cloud vs self-hosted). Graph schema design prevents cardinality explosion (store structure, not data). **Delivers:** -- Plugin interface definition and registry -- Config loader extension for integrations.yaml -- Atomic config hot-reload with fsnotify -- Existing Kubernetes tools migrated to plugin pattern +- GrafanaClient with authentication (Bearer token for Cloud, SecretWatcher integration) +- Graph schema nodes (Dashboard, Panel, Query, Metric, Service) with indexes +- Health checks and connectivity validation +- Integration lifecycle (Start/Stop/Health) and factory registration -**Addresses (from FEATURES.md):** -- Plugin discovery and lifecycle (table stakes) -- Semantic versioning with compatibility checking (table stakes) -- Config hot-reload (competitive differentiator) +**Addresses features:** +- Table stakes: Dashboard execution API access, basic connectivity +- Foundation for all other features -**Avoids (from PITFALLS.md):** -- CRITICAL-1: Uses HashiCorp go-plugin, not stdlib plugin -- CRITICAL-3: Implements atomic pointer swap for config reload from start +**Avoids pitfalls:** +- Pitfall 2 (token scope): Separate auth paths for Cloud vs self-hosted, minimal permissions +- Pitfall 4 (cardinality): Graph schema stores structure only, no time-series nodes +- Pitfall 7 (rate limiting): HTTP client with rate limiter, exponential backoff -**Stack elements:** Koanf v2.3.0 + providers, fsnotify (transitive), HashiCorp go-plugin v1.7.0 +**Confidence:** HIGH — HTTP client patterns proven in VictoriaLogs/Logz.io, graph schema extends existing FalkorDB patterns. -**Research flags:** Standard patterns, skip additional research. Well-documented in go-plugin and Koanf documentation. +--- -### Phase 2: VictoriaLogs Client & Basic Pipeline -**Rationale:** Establish reliable external integration before adding complexity of template mining. Validates that log pipeline architecture works with real VictoriaLogs instance. +### Phase 2: Ingestion Pipeline — Dashboard Sync & PromQL Parsing +**Rationale:** Build ingestion before MCP tools. PromQL parsing enables semantic graph queries ("show dashboards tracking this metric"). Incremental sync handles large Grafana instances (100+ dashboards). **Delivers:** -- HTTP client for /insert/jsonline endpoint -- Pipeline stages (normalize, batch, write) -- Kubernetes event ingestion -- Basic VictoriaLogs plugin registration -- Backpressure with bounded channels +- DashboardSyncer with incremental sync (version-based change detection) +- PromQLParser using official Prometheus library (metric extraction) +- Dashboard→Panel→Query→Metric graph population +- Concurrent fetching (worker pool), batch graph writes (transactions) + +**Addresses features:** +- Table stakes: Dashboard parsing, panel/query extraction +- Foundation for anomaly detection (need metrics in graph) -**Addresses (from FEATURES.md):** -- Log ingestion and storage (prerequisite for query tools) -- Backpressure handling (reliability) +**Avoids pitfalls:** +- Pitfall 1 (API breaking changes): Store raw dashboard JSON, defensive parsing, version detection +- Pitfall 3 (PromQL parser): Use official library, best-effort extraction, variable passthrough +- Pitfall 6 (variable edge cases): Store variables separately, do NOT interpolate during ingestion +- Pitfall 7 (rate limiting): Incremental sync, concurrent fetching with QPS limit -**Avoids (from PITFALLS.md):** -- MODERATE-4: Implements rate limiting for potential live tail -- MINOR-4: Uses correct VictoriaLogs time filter patterns +**Uses stack:** +- `prometheus/promql/parser` (new dependency) +- FalkorDB batch writes via existing graph.Client -**Stack elements:** net/http (stdlib), existing Kubernetes event stream +**Confidence:** HIGH — Incremental sync is standard pattern, PromQL parser is production-proven official library. -**Research flags:** Standard patterns, skip additional research. VictoriaLogs API is well-documented. +--- -### Phase 3: Log Template Mining -**Rationale:** Template mining is complex and can be iterated on. Start with basic Drain implementation, validate with production log samples, iterate on masking and rebalancing based on real data. +### Phase 3: Service Inference & Dashboard Hierarchy +**Rationale:** Build semantic relationships (Metric→Service, Dashboard hierarchy) before MCP tools. Service inference enables "show metrics for this service" queries. Dashboard hierarchy (overview/aggregated/detail tags) structures progressive disclosure. **Delivers:** -- Drain algorithm implementation for template extraction -- Template cache with in-memory storage -- Template persistence (WAL + snapshots) -- Integration with log pipeline -- Template metadata in VictoriaLogs logs +- Service inference from PromQL labels (job, service, app, namespace, cluster) +- Metric→Service linking with confidence scores (TRACKS edges) +- Dashboard hierarchy classification (via tags: overview, aggregated, detail) +- Variable classification (scope/entity/detail) for smart defaults -**Addresses (from FEATURES.md):** -- Automatic template mining (competitive differentiator) -- Pattern detection without manual config +**Addresses features:** +- Differentiator: Intelligent variable scoping (auto-classify variables) +- Foundation for progressive disclosure (need hierarchy) -**Avoids (from PITFALLS.md):** -- CRITICAL-2: Pre-tokenization with masking for variable-starting logs -- CRITICAL-4: Periodic rebalancing mechanism (use Drain3 HELP if available, or implement TTL) -- MINOR-3: Order normalization rules correctly (IPv6 before UUID) +**Avoids pitfalls:** +- Pitfall 5 (baseline drift): Service nodes enable per-service baselines (future) +- Pitfall 9 (label cardinality): Whitelist labels for service inference (job, service, app, namespace, cluster only) +- Pitfall 8 (gridPos): Use dashboard tags for hierarchy, not panel position -**Stack elements:** LoggingDrain library (or custom implementation) +**Confidence:** MEDIUM-HIGH — Heuristic-based classification (80% accuracy expected), configurable via manual tags. -**Research flags:** NEEDS DEEPER RESEARCH during phase planning. Drain algorithm parameters (similarity threshold, tree depth, max clusters) need tuning based on actual log patterns. Recommend `/gsd:research-phase` to: -- Sample production logs from target namespaces -- Validate template count is reasonable (<1000 for typical app) -- Tune similarity threshold (0.3-0.6 range) -- Test masking patterns with edge cases +--- -### Phase 4: MCP Query Tools -**Rationale:** Query tools depend on both VictoriaLogs client (Phase 2) and template mining (Phase 3). This phase exposes functionality to AI assistants via MCP. +### Phase 4: Query Execution & MCP Tools Foundation +**Rationale:** Deliver basic MCP tools before anomaly detection. Enables AI to query metrics and discover dashboards. Tests end-to-end flow (client → parser → graph → tools). **Delivers:** -- `query_logs` tool with LogsQL integration -- `analyze_log_patterns` tool using template data -- VictoriaLogs plugin full registration -- Tool descriptions and JSON schemas -- MCP Resources for VictoriaLogs schema docs - -**Addresses (from FEATURES.md):** -- Full-text search with time range filtering (table stakes) -- Field-based filtering, aggregation (table stakes) -- High-cardinality field search (differentiator) -- MCP Resources for context (differentiator) - -**Avoids (from PITFALLS.md):** -- MODERATE-1: Multi-version MCP protocol support -- Tool count minimization (10-20 tools, per MCP best practices) +- GrafanaQueryService (execute PromQL via Grafana API, format results) +- MCP tools: `grafana_{name}_dashboards` (list/search with filters) +- MCP tool: `grafana_{name}_query` (execute PromQL, return time series) +- MCP tool: `grafana_{name}_metrics_for_resource` (reverse lookup: resource → dashboards) -**Stack elements:** Existing mark3labs/mcp-go, VictoriaLogs client from Phase 2, templates from Phase 3 +**Addresses features:** +- Table stakes: Dashboard execution, query execution with time ranges +- Progressive disclosure structure: Three tools (dashboards, query, metrics-for-resource) -**Research flags:** Standard MCP patterns, skip additional research. Mark3labs/mcp-go provides clear tool registration API. +**Avoids pitfalls:** +- Pitfall 10 (state leakage): Stateless MCP tools, require scoping variables, AI manages context +- Pitfall 6 (variable interpolation): Pass variables to Grafana API via `scopedVars`, not interpolated locally -### Phase 5: Progressive Disclosure UI -**Rationale:** UI comes last because it depends on query tools (Phase 4) and benefits from real template data. Can iterate on UX based on actual usage patterns. +**Uses stack:** +- GrafanaClient (query execution) +- FalkorDB (semantic queries for dashboard discovery) -**Delivers:** -- Three-level drill-down (global → aggregated → detail) -- URL-based state management -- Breadcrumb navigation -- Collapsible sections for details -- Smart defaults (SLO-first view) - -**Addresses (from FEATURES.md):** -- Progressive disclosure navigation (table stakes) -- State preservation (table stakes) -- Smart defaults with SLO-first views (differentiator) +**Confidence:** HIGH — MCP tool pattern proven in VictoriaLogs/Logz.io, stateless architecture established. -**Avoids (from PITFALLS.md):** -- CRITICAL-5: URL-based state from day 1 (hard to retrofit) -- MINOR-2: Limit to 3 levels maximum (global → aggregated → detail) -- MODERATE-5: Preserve context during drill-down +--- -**Stack elements:** Existing React frontend, React Router +### Phase 5: Anomaly Detection & Progressive Disclosure +**Rationale:** Deliver competitive differentiator (anomaly detection) after foundation is stable. Progressive disclosure tools (overview/aggregated/details) complete the value proposition. -**Research flags:** Standard React patterns, skip additional research. Established SPA state management patterns. +**Delivers:** +- GrafanaAnomalyService (baseline computation with time-of-day matching, z-score comparison) +- Baseline caching in graph (MetricBaseline nodes, 1-hour TTL) +- MCP tool: `grafana_{name}_detect_anomalies` (rank by severity) +- Progressive disclosure defaults per tool level (interval, limit) -### Phase 6: Template Consistency & Monitoring (Optional) -**Rationale:** Cross-client consistency and drift monitoring are operational excellence features. Can defer if MVP targets single client or if template drift isn't observed in practice. +**Addresses features:** +- Differentiator: AI-driven anomaly detection with severity ranking +- Differentiator: Progressive disclosure pattern (overview→aggregated→details) +- Differentiator: Cross-signal correlation (metrics + logs via shared namespace/time) -**Delivers:** -- Canonical template storage in MCP server -- Deterministic template IDs (hash-based) -- Template drift detection metrics -- Template growth monitoring -- Health check endpoints +**Avoids pitfalls:** +- Pitfall 5 (baseline drift): Time-of-day matching, minimum thresholds, staleness detection +- Pitfall 13 (absent metrics): Check scrape status first (`up` metric), use `or vector(0)` pattern +- Pitfall 12 (histogram quantile): Validate `histogram_quantile()` wraps `sum() by (le)` -**Addresses (from FEATURES.md):** -- Cross-client consistency (nice-to-have) -- Template drift detection (operational excellence) +**Uses stack:** +- GrafanaQueryService (historical queries for baseline) +- stdlib math (mean, stddev, percentile calculations) +- FalkorDB (cache baselines) -**Avoids (from PITFALLS.md):** -- MODERATE-2: Ensures same template IDs across clients -- Template growth monitoring (early warning for drift) +**Confidence:** MEDIUM-HIGH — Statistical methods well-established, severity ranking heuristic needs tuning with real data. -**Research flags:** Standard patterns, skip additional research. +--- ### Phase Ordering Rationale -- **Sequential dependency chain:** Plugin infrastructure (1) → VictoriaLogs client (2) → Template mining (3) → Query tools (4) → UI (5) -- **Risk-first approach:** Critical decisions (plugin system choice, config reload pattern) in Phase 1 where changes are cheapest -- **Iterative complexity:** Start simple (basic pipeline in Phase 2), add complexity (template mining in Phase 3), iterate on UX (Phase 5) -- **Validation points:** Each phase delivers independently testable functionality (Phase 2 validates VictoriaLogs integration before adding template mining complexity) -- **Pitfall avoidance:** Phase 1 prevents CRITICAL-1 (plugin system) and CRITICAL-3 (config reload), Phase 3 prevents CRITICAL-2 and CRITICAL-4 (template mining), Phase 5 prevents CRITICAL-5 (UI state) +**Why this order:** +1. **Foundation first (Phase 1-2)**: HTTP client and graph schema are prerequisites for all other features. PromQL parsing enables semantic queries. +2. **Semantic layer (Phase 3)**: Service inference and hierarchy classification add intelligence to the graph before building tools on top. +3. **Basic tools (Phase 4)**: Deliver value early (query metrics, discover dashboards) before advanced features. Tests end-to-end flow. +4. **Differentiators last (Phase 5)**: Anomaly detection and progressive disclosure require stable foundation. These are competitive advantages, not MVP blockers. + +**Why this grouping:** +- **Phase 1**: Auth complexity is separate concern from ingestion (different failure modes) +- **Phase 2**: Dashboard sync and PromQL parsing are tightly coupled (sync needs parser) +- **Phase 3**: Service inference depends on PromQL parsing (needs label extraction) +- **Phase 4**: MCP tools depend on query service (needs execution layer) +- **Phase 5**: Anomaly detection depends on query service (needs historical data) + +**How this avoids pitfalls:** +- Early defensive parsing (Phase 2) catches API breaking changes before they block later phases +- Incremental sync (Phase 2) prevents rate limit exhaustion during initial ingestion +- Stateless tools (Phase 4) prevent progressive disclosure state leakage +- Time-of-day matching (Phase 5) mitigates baseline drift before anomaly detection ships ### Research Flags -Phases likely needing deeper research during planning: -- **Phase 3 (Template Mining):** Complex algorithm with production-sensitive tuning. Needs `/gsd:research-phase` to sample real logs, validate template count, tune parameters (similarity threshold, tree depth, masking patterns). Research questions: What's the typical template count for our log patterns? What similarity threshold prevents explosion? Which fields need masking? +**Phases likely needing deeper research during planning:** +- **Phase 3**: Service inference heuristics need validation with real-world dashboard corpus. Question: What % of dashboards use standard labels (job, service, app) vs custom labels? May need fallback discovery method (folder-based hierarchy) if tag adoption is low. +- **Phase 5**: Anomaly detection thresholds (z-score cutoffs, severity classification weights) are heuristic-based. Will need A/B testing with real metrics data to tune false positive rates. -Phases with standard patterns (skip research-phase): -- **Phase 1 (Plugin Infrastructure):** Well-documented in go-plugin and Koanf documentation, established patterns -- **Phase 2 (VictoriaLogs Client):** VictoriaLogs HTTP API is well-documented, standard Go HTTP client patterns -- **Phase 4 (MCP Query Tools):** Mark3labs/mcp-go provides clear API, existing MCP tools in codebase as reference -- **Phase 5 (Progressive Disclosure UI):** Standard React/SPA patterns, URL state management well-established +**Phases with standard patterns (skip research-phase):** +- **Phase 1**: HTTP client follows VictoriaLogs/Logz.io pattern exactly. SecretWatcher is copy-paste. +- **Phase 2**: PromQL parser is well-documented official library. Incremental sync is standard pattern. +- **Phase 4**: MCP tool pattern proven in VictoriaLogs/Logz.io. Stateless architecture established. ## Confidence Assessment | Area | Confidence | Notes | |------|------------|-------| -| Stack | HIGH | HashiCorp go-plugin (4+ years production), Koanf (stable v2), VictoriaLogs (official docs). Only MEDIUM: LoggingDrain library (small community, but algorithm is proven). | -| Features | HIGH | MCP patterns from 2026 best practices, progressive disclosure from UX research, log exploration features from VictoriaLogs docs and competitor analysis. MEDIUM: VictoriaLogs-specific query capabilities (not all features detailed in web search). | -| Architecture | HIGH | Existing codebase analysis provides foundation, external patterns verified with production examples (pipeline stages, Drain algorithm, atomic swap pattern). Interface-based plugin registry is idiomatic Go. | -| Pitfalls | MEDIUM-HIGH | Critical pitfalls verified with official sources (Go issue tracker for stdlib plugin, academic papers for Drain limitations, Go docs for atomic operations). MEDIUM: Progressive disclosure pitfalls (UX research from web only). | +| Stack | HIGH | Official Prometheus parser is production-proven (556+ dependents). FalkorDB already integrated. Custom HTTP client follows proven pattern. Only new dependency is PromQL parser. | +| Features | MEDIUM-HIGH | Table stakes verified with official Grafana docs. Differentiators (anomaly detection, progressive disclosure) based on industry best practices (RED/USE metrics, statistical baselines). MVP scope validated against competitive tools (Netdata, AWS Lookout). | +| Architecture | HIGH | Graph schema extends existing FalkorDB patterns (ResourceIdentity, ChangeEvent). MCP tool pattern proven in VictoriaLogs/Logz.io. Service layer follows existing TimelineService/GraphService design. Integration lifecycle matches plugin system. | +| Pitfalls | MEDIUM-HIGH | Critical pitfalls verified with official Grafana docs (API breaking changes, auth scope) and Prometheus GitHub issues (parser complexity). Anomaly detection seasonality is well-researched (O'Reilly book, research papers). Variable interpolation edge cases documented in Grafana issues. Some pitfalls (baseline tuning, variable chaining depth) need validation with real dashboards. | **Overall confidence:** HIGH -Research covers all critical decisions with high-confidence sources. The one MEDIUM component (LoggingDrain library) has clear mitigation (re-implement algorithm if needed). Recommended phase order follows verified dependency patterns. +The recommended stack is production-ready with minimal new dependencies. The architecture aligns perfectly with Spectre's existing patterns (FalkorDB, MCP tools, plugin system). The main uncertainties are heuristic-based (service inference, anomaly thresholds) which are tunable parameters, not architectural risks. ### Gaps to Address -**LoggingDrain library maturity (MEDIUM confidence):** Small community (16 stars), recent but limited production reports. Mitigation: Phase 3 should include spike to validate library works as expected. If bugs found, Drain algorithm is simple enough to implement in-house (200-300 LOC for core logic per research). - -**VictoriaLogs query syntax details (MEDIUM confidence):** Web search provided high-level capabilities, but full LogsQL syntax not exhaustively documented in search results. Mitigation: Consult VictoriaLogs API documentation directly during Phase 4 implementation. No blocking risk — basic query patterns are well-documented. +**Validation needed during implementation:** +- **Variable chaining depth**: Research suggests 90% of dashboards use 0-3 levels of variable chaining, but this needs validation with real-world dashboard corpus (Grafana community library sample). If >10% use deeper chaining, Phase 2 may need scope expansion. +- **Dashboard tagging adoption**: Research shows tags are standard Grafana feature, but need to verify users already tag dashboards or if this is new practice. If low adoption, Phase 3 needs fallback discovery method (folder-based hierarchy). +- **Anomaly detection false positive rate**: Statistical methods (z-score, IQR) are well-established but thresholds (2.5 sigma vs 3.0 sigma) need tuning with production data. Plan for A/B testing in Phase 5. -**Template mining parameter tuning (production-dependent):** Optimal values for similarity threshold, tree depth, and max clusters depend on actual log patterns in target environment. Mitigation: Phase 3 planning should include `/gsd:research-phase` to sample production logs and validate parameters. Research identified ranges (similarity 0.3-0.6, depth 4-6) but exact values need empirical testing. +**How to handle during planning:** +- Phase 2 planning: Include fixture dashboards with multi-value variables (2-3 levels deep) to validate parsing. Log warning if deeper chaining detected. +- Phase 3 planning: Document manual tagging workflow in UI. Design fallback: if no tags, classify by folder name patterns (overview, service, detail). +- Phase 5 planning: Make sensitivity thresholds configurable. Include "tune anomaly detection" task for post-MVP based on false positive feedback. -**Cross-client template consistency requirements (unclear):** Research identified the risk, but MVP scope doesn't clarify if multiple clients will access templates simultaneously. Mitigation: Phase 6 is marked optional, can prioritize based on actual multi-client usage patterns observed in Phases 4-5. +**Known limitations (document, do NOT block):** +- Multi-value variables deferred to post-MVP (can work around by AI providing single value) +- Query variables (dynamic) deferred to post-MVP (AI provides static values) +- Trace linking deferred (requires OpenTelemetry adoption, metrics+logs already valuable) ## Sources ### Primary (HIGH confidence) -- [HashiCorp go-plugin v1.7.0 on Go Packages](https://pkg.go.dev/github.com/hashicorp/go-plugin) — plugin architecture -- [Koanf v2.3.0 GitHub releases](https://github.com/knadh/koanf/releases) — config management -- [VictoriaLogs Official Documentation](https://docs.victoriametrics.com/victorialogs/) — log storage and querying -- [Drain3 algorithm](https://github.com/logpai/Drain3) — template mining -- [Go issue tracker (#27751, #31354)](https://github.com/golang/go/issues) — stdlib plugin limitations -- [MCP Protocol Specification](https://modelcontextprotocol.io/specification/) — MCP patterns -- [Semantic Versioning 2.0.0](https://semver.org/) — versioning -- [Nielsen Norman Group -

header format than expected +**How to avoid:** +- Grafana uses standard `Authorization: Bearer ` header (not custom like Logz.io's `X-API-TOKEN`) +- Token is from Grafana Service Account (not API key - those are deprecated) +- Both Cloud and self-hosted use same Bearer token format +**Warning signs:** 401 Unauthorized response when token exists in Secret + +### Pitfall 2: Dashboard UID vs ID +**What goes wrong:** Using deprecated numeric dashboard ID instead of UID +**Why it happens:** Older Grafana documentation mentioned ID, but it's deprecated +**How to avoid:** +- Always use UID (string, max 40 chars) for dashboard identification +- Search API returns both, but only store/use UID +- Dashboard retrieval endpoint: `/api/dashboards/uid/{uid}` not `/api/dashboards/{id}` +**Warning signs:** Inconsistent dashboard URLs across Grafana installs + +### Pitfall 3: Health Check Scope +**What goes wrong:** Health check only validates dashboard access, not datasource access +**Why it happens:** Datasource access is a separate permission in Grafana RBAC +**How to avoid:** +- Test both dashboard read (`/api/search?limit=1`) AND datasource access (`/api/datasources`) +- If datasource access fails but dashboard succeeds: return Degraded status with warning message +- Don't block integration creation - allow saving with warning +**Warning signs:** Integration appears healthy but MCP tools fail when querying metrics + +### Pitfall 4: Graph Database Naming Collision +**What goes wrong:** Multiple Grafana integrations share same graph database, causing data collision +**Why it happens:** Using static graph name like "spectre_grafana" +**How to avoid:** +- Graph name MUST include integration instance name: `spectre_grafana_{name}` +- Example: user creates "grafana-prod" and "grafana-staging" → graphs "spectre_grafana_prod" and "spectre_grafana_staging" +- When integration is deleted, delete its specific graph: `client.DeleteGraph(ctx)` +**Warning signs:** Dashboard data from one integration appears in another + +### Pitfall 5: Pagination Handling +**What goes wrong:** Only first 1000 dashboards retrieved from large Grafana instances +**Why it happens:** `/api/search` defaults to limit=1000 +**How to avoid:** +- Use `limit` (max 5000) and `page` parameters for pagination +- For initial implementation, fetch up to 5000 dashboards (single request with `?type=dash-db&limit=5000`) +- If more than 5000 dashboards exist, implement pagination loop in Phase 16 +**Warning signs:** Integration with 2000+ dashboards only shows subset + +## Code

If 200 OK, user has datasource read access. + +2. **Graph schema indexes for Dashboard nodes** + - What we know: Dashboard nodes need uid, title, tags, folder fields. Existing ResourceIdentity has indexes on uid, kind, namespace. + - What's unclear: Optimal index strategy for dashboard queries (by tag? by folder?) + - Recommendation: Start with index on uid (primary lookup), add indexes on folder and tags in Phase 16 if query performance requires. + +3. **Dashboard version tracking** + - What we know: Dashboards have version field that increments on each save + - What's unclear: Whether to track version history or just latest version + - Recommendation: Phase 15 stores only latest version.

The core technical challenges are: (1) parsing PromQL queries to extract metrics, labels, and aggregations using the official Prometheus parser library, (2) detecting dashboard changes via version field comparison for efficient incremental sync, and (3) modeling Dashboard→Panel→Query→Metric relationships in FalkorDB with proper handling of Grafana variables. + +The standard approach uses the official `github.com/prometheus/prometheus/promql/parser` library for AST-based PromQL parsing, Grafana's REST API for dashboard fetching with version-based change detection, and FalkorDB's Cypher interface for creating graph nodes and relationships. The codebase already has established patterns for integration watchers (SecretWatcher), periodic sync loops (IntegrationWatcher), and graph operations (graph.Client interface). + +**Primary recommendation:** Follow the VictoriaLogs integration pattern for consistency (SecretWatcher + config file patterns), use the Prometheus PromQL parser's Inspect function for AST traversal to extract VectorSelector nodes, and implement version-based incremental sync with full-replace semantics on dashboard update. + +## Standard Stack + +The established libraries/tools for this domain: + +### Core +| Library | Version | Purpose | Why Standard | +|---------|---------|---------|--------------| +| github.com/prometheus/prometheus/promql/parser | Latest (v2.x) | PromQL parsing and AST traversal | Official Prometheus parser, battle-tested, complete AST node types | +| github.com/FalkorDB/falkordb-go | v2 | Graph database client | Official FalkorDB Go client, Cypher query execution | +| github.com/fsnotify/fsnotify | v1.x | File watching for config reload | Standard Go file watcher, used in existing IntegrationWatcher | +| k8s.io/client-go | v0.x | Kubernetes API and informers | Standard K8s client, used in existing SecretWatcher | + +### Supporting +| Library | Version | Purpose | When to Use | +|---------|---------|---------|-------------| +| encoding/json | stdlib | JSON parsing for dashboard structure | Parse Grafana API responses and dashboard JSON | +| time | stdlib | Interval-based sync scheduling | Hourly sync intervals, debouncing | +| context | stdlib | Cancellation and timeout | Graceful shutdown, API timeouts | + +### Alternatives Considered +| Instead of | Could Use | Tradeoff | +|------------|-----------|----------| +| Prometheus parser | Write custom PromQL parser | Custom parser would be incomplete, miss edge cases, require extensive testing | +| Version-based sync | Timestamp-based sync | Timestamps have granularity issues, version is authoritative change indicator | +| FalkorDB Cypher | Direct Redis commands | Cypher provides type safety, readability, and query optimization | + +**Installation:** +```bash +go get github.com/prometheus/prometheus/promql/parser +go get github.com/FalkorDB/falkordb-go/v2 +# fsnotify and k8s.io/client-go already in project +``` + +## Architecture Patterns + +### Recommended Project Structure +``` +internal/integration/grafana/ +├── dashboard_syncer.go # Main sync orchestrator +├── dashboard_syncer_test.go +├── promql_parser.go # PromQL AST extraction +├── promql_parser_test.go +├── graph_builder.go # Graph node/edge creation +├── graph_builder_test.go +├── secret_watcher.go # Already exists +└── secret_watcher_test.go # Already exists +``` + +### Pattern 1: Incremental Sync with Version-Based Change Detection +**What:** Compare dashboard version field between local cache and Grafana API to detect changes +**When to use:** All dashboard sync operations to avoid re-syncing unchanged dashboards +**Example:** +```go +// Source: Incremental sync pattern research +type DashboardCache struct { + UID string + Version int + LastSynced time.Time +} + +func (s *DashboardSyncer) NeedsSync(dashboard GrafanaDashboard, cached *DashboardCache) bool { + if cached == nil { + return true // Never synced before + } + // Version field is authoritative for change detection + return dashboard.Version > cached.Version +} + +func (s *DashboardSyncer) SyncDashboard(ctx context.Context, dashboard GrafanaDashboard) error { + // Full replace pattern - delete all Panel/Query nodes for this dashboard + // This ensures removed panels/queries are cleaned up + if err := s.deleteExistingPanelsAndQueries(ctx, dashboard.UID);

Comprehensive test coverage: simple panels, multiple queries, variables, graceful degradation - Uses PromQLParserInterface for testability with mock parser --- internal/integration/grafana/graph_builder.go | 313 +++++++++++++ .../integration/grafana/graph_builder_test.go | 430 ++++++++++++++++++ 2 files changed, 743 insertions(+) create mode 100644 internal/integration/grafana/graph_builder.go create mode 100644 internal/integration/grafana/graph_builder_test.go diff --git a/internal/integration/grafana/graph_builder.go b/internal/integration/grafana/graph_builder.go new file mode 100644 index 0000000..59b04cf --- /dev/null +++ b/internal/integration/grafana/graph_builder.go @@ -0,0 +1,313 @@ +package grafana + +import ( + "context" + "encoding/json" + "fmt" + "time" + + "github.com/moolen/spectre/internal/graph" + "github.com/moolen/spectre/internal/logging" +) + +// GrafanaDashboard represents the structure of a Grafana dashboard +type GrafanaDashboard struct { + UID string `json:"uid"` + Title string `json:"title"` + Version int `json:"version"` + Tags []string `json:"tags"` + Panels []GrafanaPanel `json:"panels"` + Templating struct { + List []interface{} `json:"list"` // Variable definitions as JSON + } `json:"templating"` +} + +// GrafanaPanel represents a panel within a Grafana dashboard +type GrafanaPanel struct { + ID int `json:"id"` + Title string `json:"title"` + Type string `json:"type"` + GridPos GrafanaGridPos `json:"gridPos"` + Targets []GrafanaTarget `json:"targets"` +} + +// GrafanaGridPos represents the position of a panel in the dashboard grid +type GrafanaGridPos struct { + X int `json:"x"` + Y int `json:"y"` + W int `json:"w"` // width + H int `json:"h"` // height +} + +// GrafanaTarget represents a query target within a panel +type GrafanaTarget struct { + RefID string `json:"refId"` + Expr string `json:"expr"` // PromQL expression + DatasourceUID string `json:"datasource"` // Can be UID or other identifier +} + +// PromQLParserInterface defines the interface for PromQL parsing +type PromQLParserInterface interface { + Parse(queryStr string) (*QueryExtraction, error) +} + +// GraphBuilder creates graph nodes and edges from Grafana dashboard structure +type GraphBuilder struct { + graphClient graph.Client + parser PromQLParserInterface + logger *logging.Logger +} + +// NewGraphBuilder creates a new GraphBuilder instance +func NewGraphBuilder(graphClient graph.Client, logger *logging.Logger) *GraphBuilder { + return &GraphBuilder{ + graphClient: graphClient, + parser: &defaultPromQLParser{}, + logger: logger, + } +} + +// defaultPromQLParser wraps ExtractFromPromQL for production use +type defaultPromQLParser struct{} + +// Parse extracts semantic information from a PromQL query +func (p *defaultPromQLParser) Parse(queryStr string) (*QueryExtraction, error) { + return ExtractFromPromQL(queryStr) +} + +// CreateDashboardGraph creates or updates dashboard nodes and all related structure in the graph +func (gb *GraphBuilder) CreateDashboardGraph(ctx context.Context, dashboard *GrafanaDashboard) error { + now := time.Now().UnixNano() + + // 1.

results = append(results, result) + } + + return &DetailsResponse{ + Dashboards: results, + }, nil +} +``` + +### Pattern 3: Grafana Query API Request +**What:** POST to `/api/ds/query` with datasource UID, queries, and time range +**When to use:** Every panel query execution +**Example:** +```go +// Source:

c.httpClient.Do(httpReq) + // Handle response... +} +``` + +### Pattern 4: Partial Results with Errors +**What:** Return successful panel results + list of failed panels, don't fail entire request +**When to use:** Multi-panel queries where some panels may fail but others succeed +**Example:** +```go +type DashboardQueryResult struct { + DashboardUID string `json:"dashboard_uid"` + DashboardTitle string `json:"dashboard_title"` + Panels []PanelResult `json:"panels"` // Successful panels only + Errors []PanelError `json:"errors,omitempty"` // Failed panels + TimeRange string

2026-01-23T10:00:00Z" +} +``` + +### Pattern 5: Time Range Handling +**What:** Accept absolute ISO8601 timestamps, convert to Grafana API format +**When to use:** All tool parameters +**Example:** +```go +type TimeRange struct { + From string `json:"from"` // ISO8601: "2026-01-23T09:00:00Z" + To string `json:"to"` // ISO8601: "2026-01-23T10:00:00Z" +} + +func (tr TimeRange) ToGrafanaRequest()

fromMs := fromTime.UnixMilli() + toMs := toTime.UnixMilli() + + return fmt.Sprintf("%d", fromMs), fmt.Sprintf("%d", toMs) +} + +func (tr TimeRange) Validate() error { + fromTime, err := time.Parse(time.RFC3339, tr.From) + if err != nil { + return fmt.Errorf("invalid from timestamp: %w", err) + } + toTime, err := time.Parse(time.RFC3339, tr.To) + if err != nil { + return fmt.Errorf("invalid to timestamp: %w", err) + } + if !toTime.After(fromTime) { + return fmt.Errorf("to must be after from") + } + return nil +} +``` + +### Anti-Patterns to Avoid +- **Local variable interpolation:** Don't replace `$cluster` in query strings locally - pass via scopedVars to Grafana API for server-side substitution +- **Synchronous multi-dashboard queries:** Parallelize dashboard queries with goroutines (e.g., 10 dashboards × 5 panels = 50 queries can run concurrently) +- **Including PromQL in successful responses:** Only include query text in errors/empty results - keeps successful responses clean +- **Relative time ranges:** Use absolute timestamps for precision and clarity (AI needs exact bounds) +- **Failing on first error:** Collect partial results, return what worked + error list + +## Don't Hand-Roll + +Problems that look simple but have existing solutions: + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| HTTP connection pooling | Custom connection manager | `http.Client` with tuned `Transport` | Default `MaxIdleConnsPerHost=2` causes TIME_WAIT buildup; tune to 20+ | +| PromQL parsing | Regex extraction | `prometheus/promql/parser` (existing) | Complex grammar, subqueries, binary ops - parser handles edge cases | +| Time parsing | String manipulation | `time.Parse(time.RFC3339, ...)` |

classification | Custom pattern matching | `classifyVariable()` (existing in graph_builder.go) | Case-insensitive patterns for scoping/entity/detail | + +**Key insight:** The Grafana client HTTP transport requires explicit tuning - Go's default `MaxIdleConnsPerHost=2` will cause connection churn under concurrent queries (100 goroutines × 2 connections = 98 TIME_WAIT per round). Set `MaxIdleConnsPerHost=20` and `MaxConnsPerHost=20` to match expected query concurrency. + +## Common Pitfalls + +### Pitfall 1: HTTP Connection Pool Exhaustion +**What goes wrong:** Default Go HTTP client has `MaxIdleConnsPerHost=2`, causing connection churn and TIME_WAIT buildup when executing concurrent queries (e.g., 50 panels across 10 dashboards) +**Why it happens:** Go's `DefaultTransport` has conservative defaults - `MaxIdleConns=100` but `MaxIdleConnsPerHost=2`, so only 2 connections reused per host +**How to avoid:** Explicitly tune `http.Transport` in GrafanaClient +**Warning signs:** Increased latency after initial queries, `netstat` shows thousands of TIME_WAIT connections, "too many open files" errors + +**Fix:** +```go +// Source: https://davidbacisin.com/writing/golang-http-connection-pools-1 +transport := &http.Transport{ + MaxIdleConns: 100, // Global pool size + MaxConnsPerHost: 20, // Per-host connection limit + MaxIdleConnsPerHost: 20, // CRITICAL: default 2 causes churn + IdleConnTimeout: 90 * time.Second, + TLSHandshakeTimeout: 10 * time.Second, + DialContext: (&net.Dialer{ + Timeout: 5 * time.Second, + KeepAlive: 30 * time.Second, + }).DialContext, +} +httpClient := &http.Client{Transport: transport, Timeout: 30 * time.Second} +``` + +### Pitfall 2: Grafana Response Body Not Read +**What goes wrong:** HTTP connection not returned to pool, leading to connection exhaustion and "connection refused" errors +**Why it happens:** Go's HTTP client requires reading response body to completion for connection reuse (`resp.Body` must be fully read and closed) +**How to avoid:** Always use `io.ReadAll(resp.Body)` before processing, even if you plan to discard the body +**Warning signs:** Connection pool grows unbounded, new connections opened for each request despite idle pool + +**Fix:** +```go +resp, err := client.Do(req) +if err != nil { + return nil, err +} +defer resp.Body.Close() + +// CRITICAL: Always read body to completion for connection reuse +body, err := io.ReadAll(resp.Body) +if err != nil { + return nil, err +} + +if resp.StatusCode != http.StatusOK { + return nil, fmt.Errorf("query failed (status %d): %s", resp.StatusCode, string(body)) +} + +// Now parse body +var result QueryResponse +json.Unmarshal(body, &result) +``` + +### Pitfall 3: scopedVars Not Passed to Grafana API +**What goes wrong:** Dashboard variables (like `$cluster`) not substituted in queries, resulting in errors or empty results +**Why it happens:** Assuming variable substitution happens locally or that Grafana automatically fills variables +**How to avoid:** Explicitly pass `scopedVars` in every query request with user-provided values +**Warning signs:** Queries with `$cluster` return errors like "invalid label matcher", Grafana logs show "template variable not found" + +**Fix:** +```go +// Tool parameters include variable values +type ToolParams struct { + Cluster string `json:"cluster"` // Required + Region string `json:"region"` // Required + Namespace string `json:"namespace,omitempty"` +} + +// Convert to Grafana scopedVars format +scopedVars := map[string]ScopedVar{ + "cluster": {Text: params.Cluster, Value: params.Cluster}, + "region": {Text: params.Region, Value: params.Region}, +} +if params.Namespace != "" { + scopedVars["namespace"] = ScopedVar{Text: params.Namespace, Value: params.Namespace} +} + +// Include in query request +query := Query{ + RefID: "A", + Datasource: Datasource{UID: datasourceUID}, + Expr: panel.Expr, // Contains "$cluster" + ScopedVars: scopedVars, // Grafana substitutes server-side +} +``` + +### Pitfall 4: Failing Entire Request on Single Panel Error +**What goes wrong:** One panel fails (e.g., datasource auth error), entire dashboard query returns error, AI gets no data +**Why it happens:** Not implementing partial results pattern - treating multi-panel query as atomic +**How to avoid:** Execute panels independently, collect successes and failures separately, return both +**Warning signs:** Intermittent tool failures when single datasource is down, "all or nothing" results + +**Fix:** +```go +func (s *GrafanaQueryService) ExecuteDashboard(...)

Response +**What goes wrong:** Response size bloated with redundant query text, wastes tokens in AI context window +**Why it happens:** Including query for debugging/transparency without considering token cost +**How to avoid:** Only include query text in errors or when results are empty (helps debugging failures) +**Warning signs:** Response size >> data size, AI context window fills quickly + +**Fix:** +```go +type PanelResult struct { + PanelID int `json:"panel_id"` + PanelTitle string `json:"panel_title"` + Query string `json:"query,omitempty"` // Only if empty/error + Metrics

What's unclear: Exact field types for all datasource types (Prometheus vs others), handling of annotations/exemplars + - Recommendation: Start with Prometheus time_series format, add datasource-specific handling if needed in Phase 19+ + +2. **Optimal maxPanels limit for overview tool** + - What we know: Decision says 5 panels per dashboard, VictoriaLogs uses parallel queries successfully + - What's unclear: Performance impact with 10 overview dashboards × 5 panels = 50 concurrent queries + - Recommendation: Start with 5, add rate limiting or batching if Grafana rate limits encountered + +3. **Empty results vs errors distinction** + - What we know: Decision says "omit panels with no data" + - What's unclear: How to distinguish "no data in time range" (valid) from "query error" (invalid) + - Recommendation: Check Grafana response status - 200 with empty frames = no data (omit), 4xx/5xx = error (include in errors list) + +4. **Variable multi-value handling** + - What we know: scopedVars format has `text` and `value` fields + - What's unclear: How to pass multi-select variables (e.g., cluster=["us-west", "us-east"]) via scopedVars + - Recommendation: Start

Implementation Details + +### QueryDataSource Method (client.go) +- POSTs to `/api/ds/query` endpoint with proper request format +- Supports scopedVars for server-side variable substitution +- Query types: QueryRequest, Query, ScopedVar, QueryDatasource +- Response types: QueryResponse, QueryResult, DataFrame, DataFrameSchema, DataFrameField, DataFrameData +- Uses tuned HTTP transport (MaxIdleConnsPerHost=10, MaxConnsPerHost=20) + +### Response Formatter (response_formatter.go) +- DashboardQueryResult: Contains panels array + errors array for partial results +- PanelResult: Panel ID, title, query (only on empty), metrics array +- MetricSeries: Labels map, optional unit, DataPoint values array +- Timestamps converted from epoch ms to ISO8601 (RFC3339) +- Query text included only when results are empty (per CONTEXT.md decision) + +### GrafanaQueryService (query_service.go) +- TimeRange type with Validate() (ISO8601, to > from, max 7 days) and ToGrafanaRequest() (to epoch ms) +- ExecuteDashboard: fetches dashboard JSON from graph, parses panels, executes queries +- Partial results pattern: errors collected in Errors array, execution continues +- maxPanels parameter: limits panels for overview tool (0 = all) +- Fetches dashboard from graph via Cypher query + +## Decisions Made + +- Grafana query types defined in client.go alongside client methods for cohesion +- formatTimeSeriesResponse is package-private (called by query service) +- Dashboard JSON fetched from graph (not Grafana API) since it's already synced +- Only first target per panel executed (most

different root causes +- **Including outliers in baseline computation:** Consider filtering extreme values (>3 sigma) from historical data before computing mean/stddev + +## Don't Hand-Roll + +Problems that look simple but have existing solutions: + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| PromQL parsing | Regex-based parser | Existing `internal/integration/grafana/promql_parser.go` | Already parses PromQL for variable extraction in Phase 18 | +| Time-series data structures | Custom struct hierarchy | Grafana DataFrame from Phase 18 | Well-tested, handles multi-dimensional metrics | +| Graph TTL implementation | Custom timestamp cleanup | Cypher WHERE clause with expires_at | Graph database natively supports timestamp filtering | +| Metric name normalization | String manipulation | Prometheus metric naming conventions | Industry standard (metric_name{label="value"}) | +| Statistical outlier detection | Hand-rolled IQR/percentile | Simple z-score with configurable thresholds | Z-score is simpler, explainable, and sufficient for this use case | + +**Key insight:** The codebase already has infrastructure for querying metrics (Phase 18) and storing graph data (FalkorDB). Anomaly detection is purely statistical logic layered on top - don't rebuild what exists. + +## Common Pitfalls + +### Pitfall 1: Mean/StdDev Pollution from Outliers +**What goes wrong:** Computing baseline mean/stddev using historical data that includes previous anomalies inflates the baseline, causing future anomalies to be missed. +**Why it happens:** Historical data often contains spikes, outages, or other anomalies that distort statistical measures. +**How to avoid:** +- Use median instead of mean for robust central tendency +- OR filter historical data points with z-score > 3 before computing baseline +- OR use rolling baseline computation that excludes the most extreme 5% of values +**Warning signs:** Baselines drift upward over time; known incidents don't trigger anomalies in retrospective analysis. + +### Pitfall 2: Insufficient Historical Data +**What goes wrong:** Computing baseline with fewer than 3 matching time windows yields unreliable statistics (high variance, unstable mean). +**Why it happens:** New metrics, recent dashboard changes, or sparse data collection. +**How to avoid:** +- Enforce minimum 3 matching windows (per requirements) +- Silently skip metrics with insufficient history (per requirements) +- Log metrics that were skipped for observability +**Warning signs:** High false positive rate for new metrics; baselines have extremely wide stddev. + +### Pitfall 3: Mixing Weekday and Weekend Traffic +**What goes wrong:** Comparing Monday 10am to Sunday 10am creates misleading baselines (weekends often have different traffic patterns). +**Why it happens:** Naive time-of-day matching without considering day-type. +**How to avoid:** +- Separate day_type into "weekday" vs "weekend" (per requirements) +- Monday-Friday compared together, Saturday-Sunday separate +- Store day_type in baseline cache for correct matching +**Warning signs:** Weekend traffic flagged as anomalous; Monday morning spikes look normal. + +### Pitfall 4: Query Errors Halting Detection +**What goes wrong:** A single failing metric query causes entire anomaly detection to fail, losing visibility into other metrics. +**Why it happens:** Synchronous query execution with fail-fast error handling. +**How to avoid:** +- Fail fast on individual query errors (per requirements) +- Continue with remaining metrics +- Track skip count and include in output: "15 anomalies found, 3 metrics skipped due to errors" +**Warning signs:** Intermittent complete detection failures; missing anomalies on healthy metrics when one datasource is down. + +### Pitfall 5: Large Result Set Memory Pressure +**What goes wrong:** Returning thousands of anomalies from hundreds of metrics causes memory spikes and slow responses. +**Why it happens:** No result limiting, returning all detected anomalies. +**How to avoid:** +- Rank anomalies by severity first, then z-score within severity +- Limit to top 20 anomalies in overview (per requirements) +- Provide drill-down tools for full anomaly list if needed +**Warning signs:** API response times spike with dashboard size; out-of-memory errors on large deployments. + +### Pitfall 6: Scrape Status vs Value Anomalies +**What goes wrong:** Treating "metric not collected" the same as "metric value abnormal" conflates infrastructure issues with application issues. +**Why it happens:** Not checking scrape status before computing anomalies. +**How to avoid:** +- Query scrape status (e.g., `up` metric in Prometheus) +- Separate missing metrics into different output category +- Include scrape status as note field in anomaly output (per requirements) +**Warning signs:** Anomalies flagged for metrics that aren't being scraped; false positives during collector outages. + +## Code Examples + +Verified

+**When to use:** For all graph node creation (alerts, metrics, relationships) +**Example:** +```go +// Source: Existing graph_builder.go pattern +func (gb *GraphBuilder) createAlertNode(ctx context.Context, alert *AlertRule) error { + alertQuery := ` + MERGE (a:Alert {uid: $uid}) + ON CREATE SET + a.title = $title, + a.folderUID = $folderUID, + a.ruleGroup = $ruleGroup, + a.labels = $labels, + a.annotations = $annotations, + a.condition = $condition, + a.noDataState = $noDataState, + a.execErrState = $execErrState, + a.forDuration = $forDuration, + a.updated = $updated, + a.firstSeen = $now, + a.lastSeen = $now + ON MATCH SET + a.title = $title, + a.folderUID = $folderUID, + a.ruleGroup = $ruleGroup, + a.labels = $labels, + a.annotations = $annotations, + a.condition = $condition, + a.noDataState = $noDataState, + a.execErrState = $execErrState, + a.forDuration = $forDuration, + a.updated = $updated, + a.lastSeen = $now + ` + + _, err := gb.graphClient.ExecuteQuery(ctx, graph.GraphQuery{ + Query: alertQuery, + Parameters: map[string]interface{}{ + "uid": alert.UID, + "title": alert.Title, + "folderUID": alert.FolderUID, + "ruleGroup": alert.RuleGroup, + "labels": serializeJSON(alert.Labels), + "annotations": serializeJSON(alert.Annotations), + "condition": alert.Condition, + "noDataState": alert.NoDataState, + "execErrState": alert.ExecErrState, + "forDuration": alert.For, + "updated": alert.Updated.UnixNano(), + "now": time.Now().UnixNano(), + }, + }) + return err +} +``` + +### Pattern 3: PromQL Extraction and Metric Relationship +**What:** Parse alert rule PromQL expressions to extract metric names, then create MONITORS edges +**When to use:** For all alert rules with PromQL queries in their data array +**Example:** +```go +// Source: Existing graph_builder.go createQueryGraph pattern +func (gb *GraphBuilder) createAlertMetricRelationships(ctx context.Context, alert *AlertRule) error { + // Process each query in alert data array + for _, query := range alert.Data { + // Skip non-PromQL queries (e.g., expressions, reducers) + if query.QueryType != "" && query.QueryType != "prometheus" { + continue + } + + // Extract PromQL expression from model + expr := extractExprFromModel(query.Model) + if expr == "" { + continue + } + + // Parse PromQL using existing parser (reuse from dashboard queries) + extraction, err := gb.parser.Parse(expr) + if err != nil { + gb.logger.Warn("Failed to parse alert PromQL: %v", err) + continue + } + + // Skip if query has variables (can't create concrete relationships) + if extraction.HasVariables { + gb.logger.Debug("Alert query has variables, skipping metric extraction") + continue + } + + // Create MONITORS edges to each metric + for _, metricName := range extraction.MetricNames { + if err := gb.createAlertMonitorsMetric(ctx, alert.UID, metricName); err != nil { + gb.logger.Warn("Failed to create MONITORS edge: %v", err) + continue + } + } + } + return nil +} + +func (gb *GraphBuilder) createAlertMonitorsMetric(ctx context.Context, alertUID, metricName string) error { + query := ` + MATCH (a:Alert {uid: $alertUID}) + MERGE (m:Metric {name: $metricName}) + ON CREATE SET m.firstSeen = $now, m.lastSeen = $now + ON MATCH SET m.lastSeen = $now + MERGE (a)-[:MONITORS]->(m) + ` + + _, err := gb.graphClient.ExecuteQuery(ctx, graph.GraphQuery{ + Query: query, + Parameters: map[string]interface{}{ + "alertUID": alertUID, + "metricName": metricName, + "now": time.Now().UnixNano(), + }, + }) + return err +} +``` + +### Pattern 4: Transitive Service Relationships +**What:** Alert→Service relationships established through existing Metric→Service edges +**When to use:** Querying service-level alert relationships (no explicit edges needed) +**Example:** +```cypher +// Source: Graph database best practices - transitive relationships +// Query: Find all services monitored by alert X +MATCH (a:Alert {uid: $alertUID})-[:MONITORS]->(m:Metric)-[:TRACKS]->(s:Service) +RETURN DISTINCT s.name, s.cluster, s.namespace + +// Query: Find all alerts monitoring service Y +MATCH (s:Service {name: $serviceName, cluster: $cluster})<-[:TRACKS]-(m:Metric)<-[:MONITORS]-(a:Alert) +RETURN a.uid, a.title, a.labels +``` + +### Anti-Patterns to Avoid +- **Creating Alert→Service direct edges:** Violates normalization, duplicates Metric→Service relationships. Use transitive queries instead. +- **Parsing PromQL with regex:** PromQL has complex grammar (subqueries, binary ops, functions). Use official parser AST traversal. +- **Storing alert state in Alert node:** Alert state is temporal (firing/pending/normal changes frequently). Store in separate AlertStateChange nodes (Phase 21). +- **Fetching all alerts on every sync:** Use incremental sync with `updated` timestamp comparison to minimize API calls and graph writes. + +## Don't Hand-Roll + +Problems that look simple but have existing solutions: + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| PromQL parsing | Custom regex-based parser | github.com/prometheus/prometheus/promql/parser | PromQL grammar includes subqueries, binary ops, label matchers, aggregations, functions - regex cannot handle AST correctly | +| HTTP connection pooling | Default http.Client | http.Transport with tuned MaxIdleConnsPerHost | Default MaxIdleConnsPerHost=2 causes connection churn under load, existing GrafanaClient shows optimal tuning | +| Timestamp comparison logic | Manual time parsing | Use time.Time and .After() | Handles timezones, leap seconds, monotonic clock correctly | +| Alert severity extraction | Parse labels with string manipulation | Store labels as JSON, query with json_extract in Cypher | Labels are key-value maps, JSON storage enables flexible querying | +| Graph node deduplication | Check existence before create | MERGE with ON CREATE/ON MATCH | MERGE is atomic, handles concurrency correctly, avoids race conditions | + +**Key insight:** Alert sync is 90% similar to dashboard sync - reuse the DashboardSyncer pattern (list → version check → fetch → parse → graph update). The Prometheus parser handles all PromQL complexity. FalkorDB's MERGE handles deduplication atomically. + +## Common Pitfalls + +### Pitfall 1: Alert API Response Structure Mismatch +**What goes wrong:** Grafana Alerting Provisioning API returns different JSON structure than export API +**Why it happens:** Export API returns file-provisioning format, Provisioning API returns HTTP API format +**How to avoid:** Use `/api/v1/provisioning/alert-rules` endpoint (not export endpoints), test JSON parsing with real Grafana instance +**Warning signs:** Fields missing or nested differently than documentation examples, marshal/unmarshal errors + +### Pitfall 2: Alert Rule Version vs Updated Field +**What goes wrong:** Assuming alert rules have a `version` integer field like dashboards +**Why it happens:** Dashboard sync uses `version` field, but alert rules use `updated` timestamp +**How to avoid:** Use `updated` (ISO8601 timestamp string) for incremental sync comparison, not `version` +**Warning signs:** Sync logic always thinks alerts need update, timestamp parsing errors + +### Pitfall 3: PromQL Expression Location in Alert Data +**What goes wrong:** Expecting flat `expr` field, but alert data is complex nested structure +**Why it happens:** Alert rules have multi-query data array with different query types (queries, expressions, reducers) +**How to avoid:** Parse `data[].model` field (JSON-encoded), check `queryType` field, only extract from Prometheus queries +**Warning signs:** Empty metric extractions, "expr field not found" errors + +### Pitfall 4: Creating Redundant Alert→Service Edges +**What goes wrong:** Creating direct Alert→Service edges alongside existing Metric→Service edges +**Why it happens:** Intuitive to create direct relationship, but violates graph normalization +**How to avoid:** Use transitive queries `(Alert)-[:MONITORS]->(Metric)-[:TRACKS]->(Service)` instead of direct edges +**Warning signs:** Duplicate relationship maintenance code, inconsistencies between Alert→Service and Metric→Service paths + +### Pitfall 5: Storing Alert State in Alert Node +**What goes wrong:** Adding `state` field to Alert node that changes frequently (firing/pending/normal) +**Why it happens:** Seems natural to store current state with alert definition +**How to avoid:** Alert nodes store *definition* (title, labels, PromQL), AlertStateChange nodes store *timeline* (Phase 21) +**Warning signs:** Frequent Alert node updates, inability to track state history, graph write contention + +## Code Examples + +Verified patterns from codebase and official documentation: + +### Grafana Alerting API - List Alert Rules +```go +// Source: https://grafana.com/docs/grafana/latest/developer-resources/api-reference/http-api/alerting_provisioning/ +// GET /api/v1/provisioning/alert-rules + +func (c *GrafanaClient) ListAlertRules(ctx context.Context) ([]AlertRuleMeta, error) { + reqURL := fmt.Sprintf("%s/api/v1/provisioning/alert-rules", c.config.URL) + req, err := http.NewRequestWithContext(ctx, http.MethodGet, reqURL, nil) + if err != nil { + return nil, fmt.Errorf("create list alert rules request: %w", err) + } + + // Add Bearer token authentication (reuse secretWatcher pattern) + if c.secretWatcher != nil { + token, err := c.secretWatcher.GetToken() + if err != nil { + return nil, fmt.Errorf("failed to get API token: %w", err) + } + req.Header.Set("Authorization", "Bearer "+token) + } + + resp, err := c.client.Do(req) + if err != nil { + return nil, fmt.Errorf("execute list alert rules request: %w", err) + } + defer resp.Body.Close() + + // CRITICAL: Always read response body to completion for connection reuse + body, err := io.ReadAll(resp.Body) + if err != nil { + return nil, fmt.Errorf("read response body: %w", err) + } + + if resp.StatusCode != http.StatusOK { + return nil, fmt.Errorf("list alert rules failed (status %d): %s", resp.StatusCode, string(body)) + } + + var alertRules []AlertRuleMeta + if err := json.Unmarshal(body, &alertRules);

Alert nodes from alert rules - Extract PromQL expressions from AlertQuery.Model JSON field - Parse PromQL to extract metric names using existing parser - Create Metric nodes and MONITORS edges (Alert)-[:MONITORS]->(Metric) - Alert node properties: uid, title, folderTitle, ruleGroup, condition, labels, annotations, updated - Store first PromQL expression as condition field for display - Graceful handling of parse errors (log and continue with other queries) - Skip queries with variables (metric names may be templated) - Use MERGE-based upsert semantics for Alert and Metric nodes - Add integrationName field to GraphBuilder for multi-Grafana support - Update NewGraphBuilder signature to accept integrationName parameter - Update all test usages to pass integrationName parameter

expired edges filtered in queries + +### Pattern 3: State Deduplication via Last Known State +**What:** Query previous state before creating new transition edge +**When to use:** Avoiding redundant same-state transitions during periodic sync +**Example:** +```go +// Query last known state from most recent transition edge +lastState, err := getLastKnownState(alertUID) +if err != nil { + // No previous state, treat as initial state + lastState = "unknown" +} + +// Only create transition if state changed +currentState := fetchCurrentState(alertUID) +if currentState != lastState { + createStateTransitionEdge(alertUID, lastState, currentState, now) +} +``` + +**Why this works:** Grafana periodic sync may return same state multiple times - only actual transitions need storage. + +### Pattern 4: Per-Alert Staleness Tracking +**What:** Store last_synced_at timestamp on each Alert node +**When to use:** Detecting stale data when API is unavailable +**Example:** +```cypher +// Update alert node with sync timestamp on successful fetch +MATCH (a:Alert {uid: $uid, integration: $integration}) +SET a.last_synced_at = $now +``` + +**Staleness interpretation:** +- Fresh: last_synced_at within 10 minutes (2x sync interval) +- Stale: last_synced_at > 10 minutes (API likely unavailable) +- AI interprets timestamp age, no explicit stale flag needed + +### Anti-Patterns to Avoid +- **Separate AlertStateChange nodes:** Creates unnecessary query complexity - edges model transitions naturally +- **Deleting expired edges:** Application-level cleanup is complex - use TTL filtering in queries instead +- **Global last_synced timestamp:** Hides partial failures - per-alert granularity enables better diagnostics +- **Storing every sync result:** Without deduplication, identical states create noise - only store actual transitions + +## Don't Hand-Roll + +Problems that look simple but have existing solutions: + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| TTL cleanup job | Background goroutine to delete old edges | Query-time filtering: `WHERE expires_at > $now` | Avoids race conditions, simpler code, matches baseline cache pattern | +| State change detection | Complex diffing logic | Simple string comparison: `currentState != lastState` | Alert states are enumerated strings, no complex structure | +| Timestamp parsing | Custom ISO8601 parser | RFC3339 string comparison | Already proven in Phase 20, string comparison works for ISO format | +| Concurrent sync protection | Manual mutex/semaphore | Existing sync.RWMutex pattern in AlertSyncer | Phase 20 already implements thread-safe sync status | + +**Key insight:** Edge properties with TTL filtering provide time-windowed data without cleanup complexity. Baseline cache in Phase 19 already proves this pattern works in FalkorDB. + +## Common Pitfalls + +### Pitfall 1: Fetching Alert Rules Instead of Alert Instances +**What goes wrong:** `/api/v1/provisioning/alert-rules` returns rule definitions, not current state +**Why it happens:** Rule API was used in Phase 20, developer assumes same endpoint has state +**How to avoid:** Use `/api/prometheus/grafana/api/v1/rules` which returns rules WITH their alert instances +**Warning signs:** No state field in response, only rule configuration data + +### Pitfall 2: Creating Edges Without TTL +**What goes wrong:** State transition edges accumulate indefinitely, graph grows unbounded +**Why it happens:** Forgetting to set expires_at property when creating edges +**How to avoid:** Always calculate expires_at = now + 7 days when creating state transition edges +**Warning signs:** Graph size grows continuously, query performance degrades over time + +### Pitfall 3: Not Handling Missing Previous State +**What goes wrong:** Deduplication logic crashes on first sync when no previous state exists +**Why it happens:** Assuming getLastKnownState always returns a value +**How to avoid:** Treat empty result as "unknown" state, always create first transition +**Warning signs:** Panic on initial sync, "no rows returned" errors + +### Pitfall 4: Updating last_synced_at on API Errors +**What goes wrong:** Stale data appears fresh when API fails but timestamp still updates +**Why it happens:** Updating timestamp in finally block instead of success path +**How to avoid:** Only update last_synced_at AFTER successful state fetch and edge creation +**Warning signs:** Stale data not detected, sync failures hidden by fresh timestamps + +### Pitfall 5: Storing Pending State Without Understanding Grafana Semantics +**What goes wrong:** Alert appears "Pending" but might be evaluating for first time vs waiting for threshold +**Why it happens:** Not understanding Grafana's Pending period concept +**How to avoid:** Store Pending as distinct state (Normal -> Pending -> Firing is valid transition) +**Warning signs:** Confusing state history, alerts appear to flap between Pending and Normal + +### Pitfall 6: Race Conditions Between Rule Sync and State Sync +**What goes wrong:** State sync creates edges to Alert nodes that don't exist yet +**Why it happens:** Rule sync and state sync run independently on different timers +**How to avoid:** Use MERGE for Alert node in state sync, ensure node exists before creating edge +**Warning signs:** "Node not found" errors during state sync, orphaned edges + +## Code Examples + +Verified patterns from codebase and official sources: + +### Fetching Alert States from Grafana +```go +// Source:

**Alert state when query returns no data** + - What we know: Grafana has special NoData state handling configured per rule + - What's unclear: Should NoData be tracked as a distinct state or treated as Normal? + - Recommendation: Phase 21 CONTEXT.md specifies 3-state model (firing/pending/normal), map NoData -> Normal + +3. **Handling multi-dimensional alerts (multiple instances per rule)** + - What we know: Alert rules can generate multiple instances for different label combinations + - What's unclear: Should each instance have separate state tracking or aggregate to rule level? + - Recommendation: Context specifies state tracking per-alert (Alert node = rule), aggregate instance states to single rule state (worst state wins) + +4. **State transition edge uniqueness constraints** + - What we know: Multiple edges can exist with same from/to states but different timestamps + - What's unclear: Should FalkorDB index be added for faster queries? + - Recommendation: Start without index, add if query performance issues arise (7-day window is small dataset) + +5. **Cascade delete behavior verification** + - What we know: Context specifies cascade delete when alert rule deleted in Grafana + - What's unclear: Does FalkorDB automatically delete edges when node deleted, or requires explicit DETACH DELETE? + - Recommendation: Test during implementation, likely needs explicit

lowercase for consistent comparison + +**UID extraction:** +- Extract alert UID from `grafana_uid` label in Prometheus response +- Skip rules without UID (not Grafana-managed alerts) + +**TTL implementation:** +- 7-day retention via expires_at timestamp property (matches Phase 19 baseline cache pattern) +- RFC3339 string format for timestamp comparison in Cypher queries +- No cleanup job needed - filter expired edges in queries: `WHERE t.expires_at > $now` + +**State deduplication approach:** +- getLastKnownState returns "unknown" (not error) when no previous state exists +- Enables

Use established libraries that handle edge cases. + +## Common Pitfalls + +### Pitfall 1: Sample vs Population Variance +**What goes wrong:** Using wrong variance formula leads to biased baseline comparisons. + +**Why it happens:** Confusion between sample variance (N-1 divisor, unbiased estimator) and population variance (N divisor, biased estimator). + +**How to avoid:** +- Use `stat.Variance()` for sample variance (unbiased, default for unknown population) +- Use `stat.PopVariance()` for population variance (biased, only if you have full population) +- For alert baselines: use sample variance since we have a sample of history, not full population + +**Warning signs:** Baseline deviations consistently higher/lower than expected, statistical tests failing validation. + +### Pitfall 2: Time Zone Handling in Cypher Queries +**What goes wrong:** Cypher timestamp comparisons fail due to timezone mismatches between Go time.Time and RFC3339 strings in graph. + +**Why it happens:** Phase 21 stores timestamps as RFC3339 strings, Go's time.Time may have different timezone representation. + +**How to avoid:** +- Always convert Go time.Time to UTC before formatting: `timestamp.UTC().Format(time.RFC3339)` +- Use consistent timezone in all Cypher queries (UTC recommended) +- Test with timestamps from different timezones + +**Warning signs:** Queries return empty results despite data existing, off-by-hours errors in time window filtering. + +### Pitfall 3: Cache Stampede on Analysis Requests +**What goes wrong:** Multiple concurrent requests for same alert bypass cache during computation, causing duplicate expensive graph queries. + +**Why it happens:** golang-lru cache doesn't provide request coalescing, all concurrent requests miss cache simultaneously. + +**How to avoid:** +- Use singleflight pattern (golang.org/x/sync/singleflight) to coalesce concurrent requests +- First request computes, others wait for result +- Cache result once computed + +**Warning signs:** High graph database load spikes, multiple identical Cypher queries in logs, cache hit rate lower than expected. + +### Pitfall 4: Off-By-One in Sliding Window Boundaries +**What goes wrong:** Window includes/excludes boundary timestamps inconsistently, causing incorrect transition counts. + +**Why it happens:** Confusion about inclusive vs exclusive boundaries, time.After() vs time.Before() semantics. + +**How to avoid:** +- Document window boundary semantics clearly (e.g., "6-hour window: [now-6h, now)") +- Use consistent boundary operators: `>=` for start, `<` for end (makes windows non-overlapping) +- Test boundary conditions explicitly + +**Warning signs:** Flappiness scores differ by 1 transition between runs, double-counting at window boundaries. + +### Pitfall 5: Insufficient Data Handling Inconsistency +**What goes wrong:** Different functions handle <24h data differently (error vs zero vs partial result). + +**Why it happens:** CONTEXT.md specifies "minimum 24h required" but allows "use available data for 24h-7d". + +**How to avoid:** +- Return structured error with reason: `ErrInsufficientData{Available: 12*time.Hour, Required: 24*time.Hour}` +- Document minimum requirements per function (flappiness may work with less data than baseline) +- Test with various data availability scenarios (0h, 12h, 24h, 3d, 7d) + +**Warning signs:** Inconsistent error messages, some functions succeed where others fail with same data. + +### Pitfall 6: Flappiness Score Not Normalized +**What goes wrong:** Flappiness score exceeds 1.0 or doesn't scale properly across different window sizes. + +**Why it happens:** Score formula doesn't account for maximum possible transitions in window, or uses absolute counts instead of normalized values. + +**How to avoid:** +- Normalize to 0.0-1.0 range using maximum theoretical transitions (sync interval = 5 min, so 6h window = 72 possible transitions) +- Formula: `score = min(1.0, transitionCount / maxPossibleTransitions * durationPenalty)` +- Duration penalty: penalize short-lived states (CONTEXT.md requirement) + +**Warning signs:** Scores >1.0, alerts with identical behavior have different scores due to window size differences. + +## Code Examples + +Verified patterns from official sources: + +### Using gonum/stat for Standard Deviation +```go +// Source:

(2015+) | Self-adjusting, reduces manual tuning | + +**Deprecated/outdated:** +- **Nagios flapping detection (21-check window with weighted transitions):** Too complex, fixed window doesn't adapt to different alert patterns. Modern approach: simpler sliding window with continuous scoring. +- **Time-of-day baseline matching:** Assumes diurnal patterns, doesn't work for cloud-native services with variable load. Modern approach: rolling average over full 7 days. + +## Open Questions + +Things that couldn't be fully resolved: + +1. **Optimal flappiness score formula (frequency vs duration weighting)** + - What we know: Score must factor in both transition count AND duration in each state, normalized 0.0-1.0 + - What's unclear: Exact weighting between frequency penalty and duration penalty + - Recommendation: Start with `score = (transitionCount / maxPossible) * (1 - avgStateDuration / windowSize)` and tune based on user feedback in Phase 23 + +2. **Chronic threshold rationale (why 80% firing over 7 days)** + - What we know: CONTEXT.md specifies >80% time firing = chronic + - What's unclear: Why 80% specifically (vs 75% or 90%) + - Recommendation: Research shows 80% is common threshold for "persistent state" in SRE literature (Datadog, PagerDuty use similar). Acceptable starting point, make configurable for future tuning. + +3. **Minimum data for trending detection (1h vs 6h windows)** + - What we know: Trending compares last 1h to prior 6h + - What's unclear: What if alert has only 3h of history? Fail or compute partial trend? + - Recommendation: Require minimum 2h data for trending (1h recent + 1h baseline), return "insufficient data" otherwise. Document in error message. + +4. **Cache size limit (1000 entries reasonable?)** + - What we know: 5-minute TTL, typical Grafana has 100-500 alerts + - What's unclear: Memory usage per AnalysisResult entry + - Recommendation: Start with 1000 entries (2x typical alert count), monitor memory usage in production.

baseline computation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - ComputeFlappinessScore: exponential scaling for 0.0-1.0 range - 5 transitions in 6h ≈ 0.5, 10+ transitions ≈ 0.8-1.0 - Duration multipliers penalize short-lived states (1.3x) vs long-lived (0.8x) - Uses gonum/stat.Mean for average state duration calculation - ComputeRollingBaseline: 7-day rolling average with LOCF - StateDistribution: % normal/pending/firing across time period - Daily bucketing with state carryover between days - Returns sample standard deviation (N-1) via gonum/stat.StdDev - InsufficientDataError for <24h history with clear diagnostics - CompareToBaseline: deviation score in standard deviations - Absolute difference in firing percentage / stdDev - Zero stdDev returns 0.0 (avoids division by zero) - LOCF interpolation fills gaps correctly - Transition timestamp boundary handling (inclusive at period start) - All 22 tests passing with >90% coverage -

Cache key: alert UID +- Cache hit logs: "Cache hit for alert analysis {uid}" + +### State Transition Fetching + +**FetchStateTransitions** queries graph for STATE_TRANSITION edges: + +```cypher +MATCH

+ t.to_state AS to_state, + t.timestamp AS timestamp +ORDER BY t.timestamp ASC +``` + +**Key implementation details:** +- Self-edge pattern from Phase 21-01: `(Alert)-[STATE_TRANSITION]->(Alert)` +- Temporal filtering: `startTime` to `endTime` (inclusive boundaries) +- TTL check: `expires_at > now` respects 7-day TTL from Phase 21-01 +- UTC conversion: `time.UTC().Format(time.RFC3339)` before query +- Empty slice for no transitions: valid for new alerts, not error +- Per-row error handling: log warnings, skip row, continue parsing + +### Multi-Label Categorization + +**CategorizeAlert**

duration + currentState = t.ToState + } +} + +// Carry forward final state to window end +durations[currentState] += windowEnd.Sub(currentTime) +``` + +**Edge cases handled:** +- No transitions before window: default to "normal" +- Transitions spanning window boundaries: use LOCF from before +- Gap between transitions: carry forward last known state +- Window edge transitions: inclusive of startTime, exclusive of endTime + +### Error Handling + +**ErrInsufficientData** structured error type: +```go +type ErrInsufficientData struct { + Available time.Duration + Required time.Duration +} +``` + +**Insufficient data conditions:** +- Empty transitions: `Available=0, Required=24h` +- <24h history: `Available=12h, Required=24h` +- Returns error (not empty result) to clearly signal missing data + +**Graceful degradation:** +- Insufficient data for trend (<2h): skip trend, use stable-* only +- Insufficient data for baseline: propagates InsufficientDataError as ErrInsufficientData + +## Cache Performance Characteristics + +**Cache hit rate expectations:** +- High for MCP tool repeated queries (same alert within 5 minutes) +- Low for batch analysis of many alerts (each alert queried once) +- Cache miss: full graph query + computation (6-8s typical) +- Cache hit: instant return (<1ms) + +**Memory footprint:** +- 1000 entries × ~500 bytes/entry ≈ 500KB max +- LRU eviction prevents unbounded growth +- TTL expiration cleans stale entries automatically + +**Tuning parameters:** +- Size: 1000 entries (covers ~1000 unique alerts in 5-minute window) +- TTL: 5 minutes (balance freshness vs query load) +- No manual cleanup needed (TTL-based expiration) + +## Multi-Label Categorization Examples + +**Example 1: Chronic + Flapping** +```go +// Alert firing 95% of time over 7 days, but flaps frequently +categories := CategorizeAlert(transitions, now, 0.85) +// Onset: ["chronic"] +// Pattern: ["flapping"] +``` + +**Example 2: Persistent + Trending Worse** +```go +// Alert

+```go +// Alert just started 30 min ago, stable so far +categories := CategorizeAlert(transitions, now, 0.1) +// Onset: ["new"] +// Pattern: ["stable-firing"] +``` + +**Example 4: Never Fired** +```go +// Alert exists but never entered firing state +categories := CategorizeAlert([], now, 0.0) +// Onset: ["stable-normal"] +// Pattern: ["stable-normal"] +``` + +## Edge Cases Handled + +**Empty transitions (new alerts):** +- Returns `ErrInsufficientData{Available: 0, Required: 24h}` +- Not an error to fetch empty transitions (query succeeds) +- Error occurs at analysis level (insufficient data for baseline) + +**Partial data (24h-7d history):** +- Analysis succeeds with warning about partial data +- `DataAvailable` field documents actual history span +- Baseline computation uses available data (≥24h required) + +**Flapping overrides trend:** +- If `flappinessScore > 0.7`, pattern = `["flapping"]` only +- Trend analysis skipped (flapping more important signal) +- Onset still computed independently + +**Insufficient history for trend (<2h):** +- Skips trend computation +- Falls back to stable-* based on current state +- No error (graceful degradation) + +**Timestamp edge cases:** +- Transitions at window boundaries: inclusive of start, exclusive of end +- Chronological ordering: ORDER BY in Cypher ensures sorted results +- Future transitions: ignored by LOCF (only process up to currentTime) + +## Testing Coverage + +**Unit tests: 29 total** + +**Categorization tests (19):** +- All onset categories: new, recent, persistent, chronic, stable-normal +- All pattern categories: flapping, trending-worse, trending-better, stable-* +- Multi-label: chronic + flapping +- Edge cases: empty, insufficient history for trend +- LOCF duration computation: simple, with gaps, empty +- Current state: default, most recent, ignore future + +**Service tests (10):** +- Success with 7-day history +- Partial data (24h-7d) +- Insufficient data (<24h) +- Empty transitions (new alerts) +- Cache hit/miss behavior +- Flapping detection +- Chronic categorization +- Query format verification +- Filter transitions +- Current distribution computation + +**Coverage: >85%** for all new files + +## Integration Points from Phase 22-01 + +**ComputeFlappinessScore:** +- Used with 6-hour window for pattern analysis +- Score > 0.7 → "flapping" pattern category +- Exponential scaling (1 - exp(-k*count)) from Plan 22-01 + +**ComputeRollingBaseline:** +- 7-day rolling baseline with LOCF daily bucketing +- Requires ≥24h history (from Plan 22-01 decision) +- Returns `InsufficientDataError` if insufficient data + +**CompareToBaseline:** +- Computes deviation score (σ from baseline) +- Uses sample variance (N-1) from gonum/stat +- Absolute deviation for bidirectional anomaly detection + +## Phase 23 Readiness + +**MCP tools can now:** +1. Enrich alert data with historical analysis: + - `service.AnalyzeAlert(alertUID)` → full analysis result +2.

The tools follow established MCP design patterns for minimizing token consumption while enabling deep drill-down investigation. + +The standard approach uses **progressive disclosure** to reduce context window usage: overview tools return aggregated counts (minimal tokens), aggregated tools show specific alerts with compact state timelines (medium tokens), and details tools provide full historical data only when needed (maximum tokens). This three-tier pattern is well-established in both monitoring UX (Cisco XDR, Grafana) and MCP server design (MCP-Go best practices). + +Key technical decisions validated by research: mark3labs/mcp-go library provides the registration infrastructure (already in use), state timeline visualizations use compact bucket notation ([F F N N] format is standard in Grafana state timelines), and filter parameters follow optional-by-default pattern to maximize tool flexibility. + +**Primary recommendation:** Implement three tools with increasing specificity (overview → aggregated → details) using mcp-go's RegisterTool interface, compact state bucket visualization, and AlertAnalysisService integration for historical context enrichment. + +## Standard Stack + +The established libraries/tools for this domain: + +### Core +| Library | Version | Purpose | Why Standard | +|---------|---------|---------|--------------| +| github.com/mark3labs/mcp-go | current | MCP protocol implementation | Community-standard Go MCP SDK, already integrated in internal/mcp/server.go | +| integration.ToolRegistry | internal | Tool registration interface | Spectre's abstraction over mcp-go, used by all integrations | + +### Supporting +| Library | Version | Purpose | When to Use | +|---------|---------|---------|-------------| +| encoding/json | stdlib | Schema and response formatting | All MCP tools use JSON for input schemas and response marshaling | +| time | stdlib | Time range parsing and formatting | Alert tools need Unix timestamp parsing (seconds/milliseconds detection) | + +### Alternatives Considered +| Instead of | Could Use | Tradeoff | +|------------|-----------|----------| +| Three separate tools | Single "alerts" tool with mode parameter | Separate tools reduce token usage (AI only loads relevant tool definitions) per MCP best practices | +| JSON response objects | Formatted markdown text | JSON enables structured parsing, markdown optimizes for readability - use JSON with clear field names | + +**Installation:** +```bash +# Already installed - no new dependencies needed +# Phase uses existing mcp-go integration and Phase 22 AlertAnalysisService +``` + +## Architecture Patterns + +### Recommended Tool Structure +``` +internal/integration/grafana/ +├── tools_alerts_overview.go # Overview tool: counts by severity/cluster/service +├── tools_alerts_aggregated.go # Aggregated tool: specific alerts with 1h timeline +├── tools_alerts_details.go # Details tool: full state history + rule definition +└── alert_analysis_service.go # Phase 22 service (consumed by tools) +``` + +### Pattern 1: Progressive Disclosure Tool Trio +**What:** Three tools with increasing detail levels: overview (counts), aggregated (specific alerts), details (full history) + +**When to use:** For complex domains where AI needs to start broad and drill down based on findings + +**Why it works:** Reduces initial token consumption by 5-7% (MCP tool definitions load upfront). AI loads only overview tool initially, then loads aggregated/details tools when investigating specific issues. + +**Example flow:** +``` +1. AI calls overview → sees "Critical: 5 alerts (2 flapping)" +2. AI loads aggregated tool definition → calls with severity=Critical filter +3. AI sees specific alert with CHRONIC category and high flappiness +4. AI loads details tool definition → calls for that specific alert_uid +``` + +### Pattern 2: Integration Service Consumption +**What:** MCP tools call AlertAnalysisService.AnalyzeAlert() to enrich alert data with historical context + +**When to use:** When Phase 22 service already provides computation-heavy analysis (flappiness, categorization, baseline) + +**Implementation:** +```go +// In tool Execute method +integration := getGrafanaIntegration(integrationName) +analysisService := integration.GetAnalysisService() +if analysisService == nil { + // Graph disabled or service unavailable - return basic data without analysis + return buildBasicResponse(alerts), nil +} + +// Enrich alerts with analysis +for _, alert := range alerts { + analysis, err := analysisService.AnalyzeAlert(ctx, alert.UID) + if err != nil { + // Handle ErrInsufficientData gracefully - skip enrichment for this alert + continue + } + alert.FlappinessScore = analysis.FlappinessScore + alert.Category = formatCategory(analysis.Categories) +} +``` + +**Why it matters:** Phase 22 already caches analysis results (5-minute TTL). Tools should leverage cache, not duplicate computation. + +### Pattern 3: Optional Filter Parameters +**What:** All filter parameters optional with sensible defaults (no filters = show all data) + +**When to use:** Always - follows MCP best practice and Spectre's existing tools pattern + +**Schema example:** +```go +inputSchema := map[string]interface{}{ + "type": "object", + "properties": map[string]interface{}{ + "severity": map[string]interface{}{ + "type": "string", + "description": "Optional: filter by severity (Critical, Warning, Info)", + "enum": []string{"Critical", "Warning", "Info"}, + }, + "cluster": map[string]interface{}{ + "type": "string", + "description": "Optional: filter by cluster name", + }, + // ... more optional filters + }, + "required": []string{}, // NO required parameters - all optional +} +``` + +**Source:** internal/integration/victorialogs/tools_overview.go lines 17-20 (namespace is optional) + +### Pattern 4: Compact State Timeline Visualization +**What:** State buckets displayed as [F F N N F F] using single-letter codes + +**When to use:** For time series state data in text-based AI interfaces (reduces tokens dramatically) + +**Format specification:** +- **F** = firing +- **N** = normal +- **P** = pending +- Buckets read left-to-right (oldest → newest) +- 10-minute buckets (6 per hour) for 1h default lookback +- Example: [F F F N N N] = fired for 30min, then normal for 30min + +**Why this works:** Grafana state timeline visualization uses similar compact representation. Reduces 1h timeline from ~60 datapoints (600+ tokens) to 6 characters (<10 tokens). + +**Source:** Grafana state timeline documentation - represents states as colored bands with duration, text equivalent uses symbols + +### Pattern 5: Stateless Tool Design with AI Context Management +**What:** Tools store no state between calls - AI manages context across tool invocations + +**When to use:** Always for MCP tools (protocol requirement) + +**Implementation:** +```go +// BAD - stateful design +var lastOverviewResult *OverviewResponse +func (t *OverviewTool) Execute() { + // Store result for later use + lastOverviewResult = result +} + +// GOOD - stateless design +func (t *OverviewTool) Execute(ctx context.Context, args []byte) (interface{}, error) { + // Parse params, query data, return result + // No side effects, no stored state + return result, nil +} +``` + +**Why it matters:** MCP servers may handle multiple concurrent AI sessions. Stateless tools avoid race conditions and enable proper caching at service layer (Phase 22). + +### Anti-Patterns to Avoid +- **Single monolithic alert tool:** Violates progressive disclosure - loads all functionality upfront consuming tokens unnecessarily +- **Required filter parameters:** Forces AI to specify values even when wanting all data - makes exploration harder +- **Verbose state timelines:** Returning full timestamp arrays wastes tokens - use compact bucket notation +- **Tool-level caching:** Phase 22 AlertAnalysisService already caches - don't add second cache layer +- **Mixing analysis computation in tools:** Tools should call AlertAnalysisService, not reimpute flappiness/categorization + +## Don't Hand-Roll + +Problems that look simple but have existing solutions: + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| MCP tool registration | Custom registration logic | integration.ToolRegistry interface | Already implemented in internal/mcp/server.go, handles mcp-go adaptation | +| Flappiness detection | Tool-level state change counting | AlertAnalysisService.AnalyzeAlert() | Phase 22 implements exponential scaling, duration multipliers, 6h windows with caching | +| Alert categorization | Tool-level category logic | AnalysisResult.Categories | Phase 22 implements multi-label categorization (onset + pattern dimensions) | +| Baseline comparison | Tool-level statistical analysis | AnalysisResult.DeviationScore | Phase 22 implements 7-day LOCF baseline with variance computation | +| Time range parsing | Custom timestamp parsing | parseTimeRange() from victorialogs tools | Already handles seconds vs milliseconds detection, defaults to 1h lookback | +| State timeline formatting | Full datapoint arrays | Compact bucket notation [F N P] | Reduces token count by 95%+ while preserving critical pattern information | + +**Key insight:** Phase 22 built heavy analysis infrastructure specifically for Phase 23 consumption. Tools are thin adapters that filter/format data, not reimplementations of analysis logic. + +## Common Pitfalls + +### Pitfall 1: Ignoring ErrInsufficientData from AlertAnalysisService +**What goes wrong:** Tool crashes or returns error when new alerts lack 24h history + +**Why it happens:** AlertAnalysisService requires 24h minimum for statistical analysis (Phase 22 decision) + +**How to avoid:** +```go +analysis, err := analysisService.AnalyzeAlert(ctx, alertUID) +if err != nil { + var insufficientData ErrInsufficientData + if errors.As(err, &insufficientData) { + // New alert -

-**Tuning for different workloads**: - -| Workload | Block Size | FP Rate | Tradeoff | -|----------|-----------|---------|----------| -| High-volume (1000+ evt/min) | 512KB | 5% | Fewer blocks, higher FP | -| Medium (100-1000 evt/min) | 256KB | 5% | Good balance (default) | -| Low-volume (<100 evt/min) | 64KB | 3% | More blocks, better precision | -

-**Step 3: Filter within blocks and merge** -``` -Block 0 (decompressed): 195 events - ├─ Filter: kind=Deployment AND namespace=default - ├─ Result: 42 events match - └─ Merge to results - -Block 1 (decompressed): 198 events - ├─ Filter: kind=Deployment AND namespace=default - ├─ Result: 38 events match - └─ Merge to results - -Total: 80 events returned -``` - -**Performance metrics**: -``` -Files read: 2 -Blocks decompressed: 2 out of 600 (0.3%) -Decompression time: ~20ms (2 × 256KB blocks) -Filtering time: ~5ms (check ~400 events) -Total query time: ~30ms -``` - -**Why so fast**: -1. Index tells us exactly which blocks have Deployments AND default namespace -2. We skip 99.3% of blocks (no decompression overhead) -3. Only decompressing 2 blocks instead of 300 - -### Comparison: Without Inverted Indexes - -If we only had bloom filters (no inverted indexes): -``` -Block search: - - Block 0: Bloom says "might have Deployment" (true) AND "might have default" (true) - → Decompress - - Block 1: Bloom says "might have Deployment" (true) AND "might have default" (true) - → Decompress - - Block 2: Bloom says "might have Deployment" (false) AND "might have default" (true) - → Could skip (positive logic) - - ... etc - -Estimated blocks to decompress: ~15-20 (5-7% of total) -Time: Much slower than inverted index approach -``` - -**Why both exist**: -- **Inverted indexes**: Fast-path when available -- **Bloom filters**: Fallback if indexes corrupted, early filtering without index lookup - ---- - -## Compression & Storage Efficiency - -### Compression Ratio Breakdown - -For a typical Kubernetes event (1.8KB uncompressed): - -``` -Raw JSON: 1800 bytes - │ - ├─ Remove redundant fields: 1500 bytes (-17%) -

-| Workload | Ratio | Details | -|----------|-------|----| -| High-churn cluster (many updates) | 18-20% | Repetitive namespace/kind data compresses well | -| Stable cluster (few updates) | 22-25% | Less repetition, slightly worse ratio | -| Mixed workload | 20-24% | Typical production scenario | - -**Factors affecting compression**: -1. **Event repetition**: Same namespace/kind appearing multiple times (reduces with larger blocks) -2. **Resource churn**: More updates = more similar events = better compression -3. **Block size**: Larger blocks = better compression (more context for zstd) -4. **Encoding**: JSON (default) ~20% worse than protobuf (optional, v1.1+) - ---- - -## Error Handling & Debugging - -### Common Issues - -**Issue: File footer checksum failed** -``` -Error: Block 5 failed checksum validation -Action: Block 5 is skipped, query continues with other blocks -Debugging: Check if disk corruption occurred - hexdump -C | grep -A 5 'Block 5 data' -``` - -**Issue: Index section corrupted** -``` -Error: Failed to parse IndexSection JSON -Action: Fall back to bloom filter scan (slower) -Debugging: Check if index write was interrupted - Check file modification time vs expected time - Verify file footer magic bytes are valid -``` - -**Issue: Inverted index incomplete** -``` -Scenario: Query for kind=Pod returns blocks [0,1,2] via index - But actual blocks containing Pod: [0,1,2,3] - (Block 3 missing from index) -Action: Bloom filters ensure "no false negatives" - If query sees false negatives, fallback to full scan -``` - -### Troubleshooting Checklist - -``` -☐ Verify file header magic bytes: "RPKBLOCK" -☐ Verify file footer magic bytes: "RPKEND" -☐ Check file size matches footer index offset + index length + 324 -☐ Validate CRC32 checksum (if enabled) -☐ Check all block IDs are sequential starting from 0 -☐ Verify index section JSON parses -☐ Confirm no orphaned blocks (blocks not in index) -☐ Check timestamp ordering: block.min ≤ block.max -☐ Validate event counts: reported count matches actual decompressed events -``` -

-## Deployment - -### Standalone Deployment - -```bash -# Run MCP server independently -spectre mcp --spectre-url http://spectre-api:8080 --http-addr :8081 -``` - -### Kubernetes Deployment (Sidecar) - -The Helm chart includes an optional MCP sidecar container: - -```yaml -# values.yaml -mcp: - enabled: true - spectreURL: "http://localhost:8080" - httpAddr: ":8081" - port: 8081 -``` - -The sidecar: -- Runs alongside the main Spectre container -- Connects to Spectre via localhost -- Exposes MCP on port 8081 -- Includes health checks and resource limits - -### Docker Compose - -```yaml -version: '3.8' -services: - spectre: - image: spectre:latest - command: ["--api-port=8080", "--data-dir=/data"] - volumes: - - spectre-data:/data - ports: - - "8080:8080" -

-## Testing - -### HTTP Transport Test -```bash -# Run HTTP transport integration test -go test -v ./tests/e2e -run TestMCPHTTPTransport -timeout 30m -``` - -### stdio Transport Test -```bash -# Run stdio transport integration test -go test -v ./tests/e2e -run TestMCPStdioTransport -timeout 30m -``` - -### Both Transports -```bash -# Run all MCP tests -go test -v ./tests/e2e -run "TestMCP.*Transport" -timeout 30m -``` - -## Protocol Specification - -The MCP server implements the [Model Context Protocol specification](https://modelcontextprotocol.io/specification/2025-06-18/basic/transports). - -**Supported features:** -- ✅ JSON-RPC 2.0 -- ✅ Tools (list, call) -- ✅ Prompts (list, get) -- ✅ Logging (setLevel) -- ✅ HTTP transport -- ✅ stdio transport -- ✅ Session initialization - -## Architecture - -``` -cmd/spectre/commands/mcp.go # Command entry point -internal/mcp/ - ├── protocol.go # MCP protocol types - ├── handler.go # Transport-agnostic handler - ├── server.go # Core MCP server - └── transport/ - ├── http/transport.go # HTTP transport - └── stdio/transport.go # stdio transport -``` - -The architecture uses a **transport abstraction** pattern: -1. **Handler** processes MCP requests independently of transport -2. **Transports** handle I/O and message delivery -3. **Server** manages tools and prompts - -This design allows easy addition of new transports (e.g., WebSocket) without changing core logic. - -## Troubleshooting - -### HTTP Transport - -**Problem**: Connection refused -```bash -# Check if server is running -curl http://localhost:8081/health - -# Check logs for startup errors -spectre mcp --log-level debug -``` - -**Problem**: Can't connect to Spectre API -```bash -# Verify Spectre API is accessible -curl http://localhost:8080/health - -# Update spectre-url flag -spectre mcp --spectre-url http://correct-host:8080 -``` - -### stdio Transport - -**Problem**: No output on stdout -- Ensure you're sending valid JSON-RPC 2.0 messages -- Check stderr for error logs -- Verify newline-delimited JSON format - -**Problem**: Subprocess hangs -- Check that stdin is not blocked -- Ensure messages don't contain embedded newlines -- Verify proper UTF-8 encoding - -**Problem**: Logs mixed with output -- In stdio mode, logs automatically go to stderr -- Only MCP messages appear on stdout - -## Security Considerations - -1. **Authentication**: MCP server does not implement authentication. Use network policies or reverse proxies for access control. -2. **Authorization**: All clients have full access to all tools. Deploy MCP server with same permissions as Spectre. -3. **Resource Limits**: Tool parameters have built-in limits to prevent excessive resource usage. -4. **Network Isolation**: In Kubernetes, use network policies to restrict MCP server access. - -## Performance - -- **HTTP Transport**: Supports multiple concurrent clients with connection pooling -- **stdio Transport**: Single client per subprocess, minimal overhead -- **Tool Execution**: Tools query Spectre API, performance depends on cluster size and time ranges -- **Memory**: ~64Mi typical, ~256Mi limit recommended -- **CPU**: Minimal (50m request, 200m limit recommended) diff --git a/docs-backup/OPERATIONS.md b/docs-backup/OPERATIONS.md deleted file mode 100644 index 6146b89..0000000 --- a/docs-backup/OPERATIONS.md +++ /dev/null @@ -1,620 +0,0 @@ -# Operations Guide: Kubernetes Event Monitor - -**Purpose**: Reference guide for running and maintaining the Kubernetes Event Monitoring System in production - ---- - -## Table of Contents - -1.
