Supported OS
This check monitors Kubernetes Scheduler, part of the Kubernetes control plane.
Note: This check does not collect data for Amazon EKS clusters, as those services are not exposed.
The Kubernetes Scheduler check is included in the Datadog Agent package. No additional installation is needed on your server.
See the Autodiscovery Integration Templates for guidance on applying the parameters below.
Edit the kube_scheduler.d/conf.yaml file, in the conf.d/ folder at the root of your Agent’s configuration directory to start collecting your kube_scheduler performance data. See the sample kube_scheduler.d/conf.yaml for all available configuration options.
Collecting logs is disabled by default in the Datadog Agent. To enable it, see Kubernetes Log Collection.
| Parameter | Value |
|---|---|
<LOG_CONFIG> | {"source": "kube_scheduler", "service": "<SERVICE_NAME>"} |
