Summary

Fix a critical sort bug in latency percentile calculation and add a zero-dependency Prometheus metrics handler.

Bug Fixes

  • Fix GetLatencyPercentile: latency slice was not sorted before percentile calculation, returning incorrect values
  • Fix GetMetricsSnapshot: nested RLock on non-reentrant sync.RWMutex caused potential deadlock; inlined computation within single lock scope

What's New

  • MetricsHandler(pool) returns an http.Handler serving Prometheus text exposition format
  • Metrics exposed: pyproc_requests_total, pyproc_request_duration_seconds, pyproc_workers_total, pyproc_workers_healthy, pyproc_inflight_requests, pyproc_worker_restarts_total
  • Monitoring guide with Prometheus scrape config, Grafana dashboard JSON, and alerting rules

Files

  • pkg/pyproc/pool_metrics.go (bug fix + refactor)
  • pkg/pyproc/metrics_handler.go (new)
  • pkg/pyproc/metrics_handler_test.go (new)
  • docs/deployment/monitoring.md (rewritten)
