v1.4.0

[github.com/gardener/logging:v1.4.0]

🏃 Others

• [OPERATOR] Records without a matching log destination are now unconditionally dropped (returning no error) instead of returning an error in non-OpenTelemetry-Collector configurations. by @nickytd [#466]

v1.3.0

[github.com/gardener/logging:v1.3.0]

✨ New Features

• [OPERATOR] Introduced support for dynamic logging clients based on OpenTelemetryCollector resources. Set WatchOpenTelemetryCollector: true along with OpenTelemetryCollectorLabelSelector and OpenTelemetryCollectorNamespaceLabelSelector to enable the new mode; the default Cluster-based mode is unchanged. by @nickytd [#462]

🏃 Others

• [OPERATOR] Build tooling dependencies (golangci-lint, gci, gotestsum, kind, addlicense, gosec) have been moved to a separate Go module at tools/go.mod, decoupling them from the main project module and reducing noise in go.mod/go.sum. by @nickytd [#461]

v1.2.0

[github.com/gardener/logging:v1.2.0]

🏃 Others

• [OPERATOR] Controller-runtime cache is now restricted to only watch Cluster objects and strips managed fields from cached resources, reducing memory usage and API server load. by @nickytd [#455]
• [OPERATOR] Switched from the full github.com/gardener/gardener dependency to the minimal github.com/gardener/gardener/pkg/apis package. Replaced Gardener's extension controller ShootFromCluster with a local helper and the Gardener logger with the project's own pkg/log logger. Kubernetes libraries bumped to v0.35.1. by @nickytd [#454]
• [DEVELOPER] Updated dependencies including golangci-lint and various Go tooling packages, addressed linter feedback with appropriate security annotations and style suppressions, and improved Makefile go fix command. by @nickytd [#451]
• [DEVELOPER] Modernized codebase with go fix: replaced traditional for loops with range loops and added automated go fix validation to CI pipeline by @nickytd [#450]

v1.1.0

[github.com/gardener/logging:v1.1.0]

✨ New Features

• [OPERATOR] Integrated controller-runtime for improved Kubernetes resource management and observability. Enabled OpenTelemetry SDK metrics for self-instrumentation. by @nickytd [#443]

🐛 Bug Fixes

• [OPERATOR] Improved error handling in dque batch processor: automatically cleanup partial state when dque creation fails, and provide more descriptive queue-full error messages including queue name. by @nickytd [#449]

🏃 Others

• [USER] During plugin creation and stop, redact credentials from configured endpoints when logging success info message. by @relusc [#434]
• [DEVELOPER] Standardized configuration key naming conventions for Shoot and Seed controller log routing (fixes typos, adds consistent "isin" prefixes). Enhanced DQueBatchProcessor logging with path details and reduced log verbosity. Updated Go to 1.25.7. by @nickytd [#442]

v1.0.0

[github.com/gardener/logging:v1.0.0]

⚠️ Breaking Changes

• [OPERATOR] Introduces a new v1 OTLP-based output plugin, replacing the previous Vali-specific implementation. This is a breaking change: the Go module path is now github.com/gardener/logging/v1, the plugin name is gardener, and the configuration schema is completely new. The plugin now supports OTLP (gRPC/HTTP) backends and features a persistent disk-based queue for improved reliability. The vali-curator and telegraf components have been removed. by @nickytd [#408]

✨ New Features

• [OPERATOR] Introduced optional OTEL SDK BatchProcessor for low-latency log processing. Operators can now choose between disk-persisted DQue batching (default) and in-memory SDK batching via the UseSDKBatchProcessor configuration option. Standardized client type values to use underscore notation (otlp_grpc, otlp_http, stdout, noop). by @nickytd [#425]

🏃 Others

• [OPERATOR] Simplified OTLP metrics provider setup to use package-level initialization instead of lazy singleton pattern, improving startup reliability and code maintainability. by @nickytd [#427]

v0.71.0

[github.com/gardener/logging:v0.71.0]

📌 NOTE

v0.71.0 is the last release of valitail based plugin. The development of v0 is discontinued. The source code will reside in "legacy" branch.

v1 of the output plugin introduces support for Opentelemetry logs and OTLP enabled clients. This is major a re-design and implementation which is NOT backward compatible with v0!
