DBAAS-7956: Percona MySQL metrics — full catalog and aggregation#354
Conversation
On DOKS nodes the dbaas do-agent sidecar shares a per-droplet rate-limit bucket with the system do-node-agent DaemonSet. A single retry was insufficient for double-collisions. This adds 3 retries (10s, 15s, 20s backoff) and resets lastFlushAttempt after each to prevent the internal rate limiter from blocking subsequent attempts. Made-with: Cursor
…re gap After 429 retries the agent has already spent ~45s backing off. The additional full-cycle sleep (120s) created a ~5 min gap before the next successful push. Removing it shrinks recovery to ~2.5 min (one missed cycle), which stays within the 5m PromQL rate window. Made-with: Cursor
Replace the initial 10-metric POC whitelist with the complete set covering global status, InnoDB status/variables, info_schema InnoDB metrics, perf_schema file events, Group Replication member status, replication lag, and transaction certifier/flow metrics. Made-with: Cursor
…metrics Strip command/operation/event_name labels from commands_total, innodb_row_ops_total, and perf_schema file_events to collapse per-value series into summed totals, preventing cardinality from exceeding Sonar's batch size limit. Made-with: Cursor

Summary
Adds full metric support for the Advanced MySQL (Percona) offering: expanded whitelist, cardinality-safe aggregation rules, and resilient delivery under DOKS rate-limit collisions.
