# Kubernetes Metrics Reference

Kubernetes Metrics ReferenceDetails of the metric data that Kubernetes components export.Metrics (v1.34)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 MetricsStable metrics observe strict API contracts and no labels can be added or removed from stable metrics during their lifetime.apiserver_admission_controller_admission_duration_secondsAdmission controller latency histogram in seconds, identified by name and broken out for each operation and API resource and type (validate or admit).Stability Level:STABLEType: HistogramLabels:nameoperationrejectedtypeapiserver_admission_step_admission_duration_secondsAdmission sub-step latency histogram in seconds, broken out for each operation and API resource and step type (validate or admit).Stability Level:STABLEType: HistogramLabels:operationrejectedtypeapiserver_admission_webhook_admission_duration_secondsAdmission webhook latency histogram in seconds, identified by name and broken out for each operation and API resource and type (validate or admit).Stability Level:STABLEType: HistogramLabels:nameoperationrejectedtypeapiserver_current_inflight_requestsMaximal number of currently used inflight request limit of this apiserver per request kind in last second.Stability Level:STABLEType: GaugeLabels:request_kindapiserver_longrunning_requestsGauge of all active long-running apiserver requests broken out by verb, group, version, resource, scope and component.
