Overview

This check monitors Kube_metrics_server v0.3.0+, a component used by the Kubernetes control plane.

The Kube_metrics_server check is included in the Datadog Agent package. No additional installation is needed on your server.

To configure this check for an Agent running on a host:

Edit the kube_metrics_server.d/conf.yaml file, in the conf.d/ folder at the root of your Agent’s configuration directory to start collecting your kube_metrics_server performance data. See the sample kube_metrics_server.d/conf.yaml for all available configuration options.
Restart the Agent.

For containerized environments, see the Kubernetes Autodiscovery Integration Templates for guidance on applying the parameters below.

Parameter	Value
`<INTEGRATION_NAME>`	`kube_metrics_server`
`<INIT_CONFIG>`	blank or `{}`
`<INSTANCE_CONFIG>`	`{"prometheus_url": "https://%%host%%:443/metrics"}`

If your endpoint is secured, additional configuration is required:

Identify the certificate used for securing the metric endpoint.
Mount the related certificate file in the Agent pod.
Apply your SSL configuration. See the default configuration file for more information.

Run the Agent’s status subcommand and look for kube_metrics_server under the Checks section.
