Collect metrics from Kubernetes API Server with Elastic Agent.
What is an Elastic integration?
This integration is powered by Elastic Agent. Elastic Agent is a single, unified way to add monitoring for logs, metrics, and other types of data to a host. It can also protect hosts from security threats, query data from operating systems, forward data from remote services or hardware, and more. Refer to our documentation for a detailed comparison between Beats and Elastic Agent.
Prefer to use Beats for this use case? See Filebeat modules for logs or Metricbeat modules for metrics.
See the integrations quick start guides to get started:
This is the apiserver dataset of the Kubernetes package, in charge of retrieving metrics
from the Kubernetes API (available at /metrics).
This metricset needs access to the apiserver component of Kubernetes, accessible typically
by any POD via the kubernetes.default service or via environment
variables (KUBERNETES_SERVICE_HOST and KUBERNETES_SERVICE_PORT).
If Leader Election is activated (default behaviour) only the elastic agent which holds the leadership lock
will retrieve metrics from the apiserver.
This is relevant in multi-node kubernetes cluster and prevents duplicate data.
When the API uses https, the pod will need to authenticate using its default token and trust the server using the appropriate CA file.
Configuration example using https and token based authentication:
In order to access the /metrics path of the API service, some Kubernetes environments might
require the following permission to be added to a ClusterRole.
rules:
- nonResourceURLs:
- /metrics

- getAn example event for apiserver looks as following:
