  title: CRI-O Metrics Containers Debug API
  description: The CRI-O metrics endpoint exposes Prometheus-compatible metrics for operations, image pulls, container lifecycle, and runtime errors. Metrics are enabled with the --enable-metrics daemon flag and served on the port configured by --metrics-port (default 9090) at the /metrics path. The endpoint can also be served over a Unix socket via --metrics-socket and secured using --metrics-cert and --metrics-key for TLS.
