# Metrics & Telemetry Enhancement Plan
## Goal
Expand metrics coverage for profitability, latency, and error conditions and ensure dashboards/alerts align with SRE expectations.
## Tasks
1. **Metric Inventory**
- [ ] Catalogue existing metrics in `pkg/metrics/metrics.go` and identify gaps (profit factor, queue depth, RPC errors).
- [ ] Ensure every critical subsystem records Prometheus metrics.
2. **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.
3. **Endpoint Hardening**
- [ ] Validate authentication/IP allowlist for `/metrics` endpoint; support TLS/ingress integration.
- [ ] Add health checks for metrics server (liveness/readiness signals).
4. **Documentation**
- [ ] Extend `docs/6_operations/DEPLOYMENT_GUIDE.md` with monitoring instructions and alert-response runbooks.
