Supported OS
このチェックは、Datadog Agent を通じて Datadog Cluster Agent を監視します。
ホストで実行されている Agent 用にこのチェックをインストールおよび構成する場合は、以下の手順に従ってください。コンテナ環境の場合は、オートディスカバリーのインテグレーションテンプレートのガイドを参照してこの手順を行ってください。
Datadog-Cluster-Agent チェックは Datadog Agent パッケージに含まれています。 サーバーに追加でインストールする必要はありません。
datadog_cluster_agent のパフォーマンスデータの収集を開始するには、Agent のコンフィギュレーションディレクトリのルートにある conf.d/ フォルダーの datadog_cluster_agent.d/conf.yaml ファイルを編集します。使用可能なすべてのコンフィギュレーションオプションについては、サンプル datadog_cluster_agent.d/conf.yaml を参照してください。
Agent の status サブコマンドを実行し、Checks セクションで datadog_cluster_agent を探します。
