Metrics & Telemetry Enhancement Plan
Goal
Expand metrics coverage for profitability, latency, and error conditions and ensure dashboards/alerts align with SRE expectations.
Tasks
-
Metric Inventory
- Catalogue existing metrics in
pkg/metrics/metrics.goand identify gaps (profit factor, queue depth, RPC errors). - Ensure every critical subsystem records Prometheus metrics.
- Catalogue existing metrics in
-
Alerting & Dashboards
- Update Grafana dashboards to include new metrics; document recommended alert thresholds.
- Integrate simulation outputs to set baseline expectations for hit rate and profit.
-
Endpoint Hardening
- Validate authentication/IP allowlist for
/metricsendpoint; support TLS/ingress integration. - Add health checks for metrics server (liveness/readiness signals).
- Validate authentication/IP allowlist for
-
Documentation
- Extend
docs/6_operations/DEPLOYMENT_GUIDE.mdwith monitoring instructions and alert-response runbooks.
- Extend
