Agent Check: Kubernetes Controller Manager

Overview

This check monitors the Kubernetes Controller Manager, part of the Kubernetes control plane.

Note: This check does not collect data for Amazon EKS clusters, as those services are not exposed.

Setup

Installation

The Kubernetes Controller Manager check is included in the Datadog Agent package, so you do not need to install anything else on your server.

Configuration

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

2. Restart the Agent

This integration requires access to the controller manager's metric endpoint. To have access to the metric endpoint you should:

• have access to the IP/Port of the controller-manager process
• have get RBAC permissions to the /metrics endpoint (the default Datadog Helm chart already adds the right RBAC roles and bindings for this)

Validation

Run the Agent's status subcommand and look for kube_controller_manager under the Checks section.
