Kubernetes Metrics Reference

Details of the metric data that Kubernetes components export.

Metrics (v1.28)

This page details the metrics that different Kubernetes components export. You can query the metrics endpoint for these components using an HTTP scrape, and fetch the current metrics data in Prometheus format.

List of Stable Kubernetes Metrics

Stable metrics observe strict API contracts and no labels can be added or removed from stable metrics during their lifetime.

List of Beta Kubernetes Metrics

Beta metrics observe a looser API contract than its stable counterparts. No labels can be removed from beta metrics during their lifetime, however, labels can be added while the metric is in the beta stage. This offers the assurance that beta metrics will honor existing dashboards and alerts, while allowing for amendments in the future.

List of Alpha Kubernetes Metrics

Alpha metrics do not have any API guarantees. These metrics must be used at your own risk, subsequent versions of Kubernetes may remove these metrics altogether, or mutate the API in such a way that breaks existing dashboards and alerts.

They are not errors yet, but they will become real errors when SELinuxMountReadWriteOncePod feature is expanded to all volume access modes.
volume_manager_selinux_volume_context_mismatch_errors_totalALPHAGaugeNumber of errors when a Pod uses a volume that is already mounted with a different SELinux context than the Pod needs. Kubelet can’t start such a Pod then and it will retry, therefore value of this metric may not represent the actual nr. of Pods.
volume_manager_selinux_volume_context_mismatch_warnings_totalALPHAGaugeNumber of errors when a Pod uses a volume that is already mounted with a different SELinux context than the Pod needs. They are not errors yet, but they will become real errors when SELinuxMountReadWriteOncePod feature is expanded to all volume access modes.
volume_manager_selinux_volumes_admitted_totalALPHAGaugeNumber of volumes whose SELinux context was fine and will be mounted with mount -o context option.
