Merged
Merged
Conversation
Expose Prometheus metrics from the controller pod so operators can
SLO and alert on reconcile health without scraping logs.
* New controller/src/metrics.rs registering two IntCounterVecs:
azureclaw_controller_reconcile_errors_total{crd_kind, error_class}
azureclaw_controller_reconcile_retries_total{crd_kind}
* New controller/src/metrics_server.rs — axum server exposing
/metrics + /healthz on $CONTROLLER_METRICS_ADDR (default :9091).
* All eight error_policy fns wired to record_reconcile_error().
* Helm controller-deployment.yaml declares containerPort 9091.
* Controller Cargo.toml adds axum 0.8.
* 4 new unit tests; controller bin 345 → 349. Clippy / fmt / helm
lint clean.
