Datadog Cluster Agent

Supported OS Linux Mac OS Windows

Integration version3.1.1

Overview

This check monitors the Datadog Cluster Agent through the Datadog Agent.

Setup

Follow the instructions below to install and configure this check for an Agent running on a host. For containerized environments, see the Autodiscovery Integration Templates for guidance on applying these instructions.

Installation

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

Configuration

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

  2. Restart the Agent.

Validation

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