Supported OS
このチェックは、Kubernetes Control Plane の一部である Kubernetes Scheduler を監視します。
注: サービスが公開されていないため、このチェックは Amazon EKS クラスターのデータを収集しません。
Kubernetes Scheduler 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。
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、次のパラメーターを適用してください。
kube_scheduler のパフォーマンスデータの収集を開始するには、Agent の構成ディレクトリのルートにある conf.d/ フォルダーの kube_scheduler.d/conf.yaml ファイルを編集します。使用可能なすべての構成オプションの詳細については、サンプル kube_scheduler.d/conf.yaml を参照してください。
Datadog Agent で、ログの収集はデフォルトで無効になっています。有効にする方法については、Kubernetes ログ収集を参照してください。
