Kubernetes Metrics Reference

Details of the metric data that Kubernetes components export.

Metrics (v1.29)

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.
