Datadog Agent の 5.17.0 リリース版では、Kubernetes イベントコレクター用に組み込みの[leader election オプション][9]をサポートしています。これを有効にした後は、クラスターに追加のイベントコレクションコンテナをデプロイする必要はありません。代わりに、Agent が一度に 1 つの Agent インスタンスのみがイベントを収集するように調整します。使用できるイベントは以下のとおりです。
Kubernetes チェックは、次のサービスチェックを含みます。
kubernetes.kubelet.check:CRITICAL の場合、kubernetes.kubelet.check.ping または kubernetes.kubelet.check.syncloop は、CRITICAL または NO DATA の状態になります。
kubernetes.kubelet.check.ping:CRITICAL または NO DATA の場合、Kubelet の API は使用できません
kubernetes.kubelet.check.syncloop:CRITICAL または NO DATA の場合、コンテナを更新する Kubelet の同期ループは機能しません。
kubernetes_state.node.ready:
クラスターノードの準備ができていない場合は CRITICAL を返します。それ以外の場合は OK を返します。
kubernetes_state.node.out_of_disk:
クラスターノードにディスク容量がない場合は CRITICAL を返します。。それ以外の場合はOK を返します。
kubernetes_state.node.disk_pressure:
クラスターノードがディスク圧縮状態の場合は CRITICAL を返します。それ以外の場合は OK を返します。
kubernetes_state.node.memory_pressure:
クラスターノードがメモリ圧縮状態の場合は CRITICAL を返します。それ以外の場合は OK を返します。
