Details of the metric data that Kubernetes components export.
Metrics (v1.36)
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.
