cgn-telemetry

Tracing, OTLP export, and Prometheus exposition shared by every Cognitora binary.

init wires a tracing-subscriber with EnvFilter (driven by RUST_LOG), optionally enables OTLP-over-tonic export when an endpoint is configured, and registers a process-wide Prometheus registry. The admin_router returns an axum Router that serves /metrics, /healthz, and /readyz for use by the orchestrator and load balancers.
