インテグレーションバージョン2.1.0

概要

このチェックは、Datadog Agent を通じて Argo Rollouts を監視します。

セットアップ

Kubernetes 環境で実行されている 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。コンテナ環境での構成の詳細については、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ください。

インストール

Agent リリース 7.53.0 から、Argo Rollouts チェックは Datadog Agent パッケージに含まれています。お使いの環境に追加インストールする必要はありません。

このチェックは、OpenMetrics を使って、Argo Rollouts が公開している OpenMetrics エンドポイントからメトリクス を収集します。これには Python 3 が必要です。

構成

Argo Rollouts コントローラーでは、ポート 8090/metrics で Prometheus 形式のメトリクスが容易に利用可能です。Agent がメトリクスの収集を開始するには、Argo Rollouts ポッドにアノテーションを付ける必要があります。アノテーションの詳細については、オートディスカバリーインテグレーションテンプレートを参照してください。その他の構成オプションについては、サンプル argo_rollouts.d/conf.yaml を参照してください。

: リストされたメトリクスは、利用可能な場合にのみ収集できます。一部のメトリクスは、特定のアクションが実行されたときにのみ生成されます。例えば、argo_rollouts.info.replicas.updated メトリクスは、レプリカの更新後にのみ公開されます。

Argo Rollouts チェック の構成に必要なパラメーターはこれだけです。

  • openmetrics_endpoint: このパラメーターには、Prometheus 形式のメトリクスが公開される場所を設定する必要があります。デフォルトのポートは 8090 です。コンテナ環境では、%%host%%ホストの自動検出に使用します。

ログ収集

Agent バージョン 6.0 以降で利用可能

Argo Rollouts のログは、Kubernetes を通じて、異なる Argo Rollouts ポッドから収集することができます。Datadog Agent では、ログの収集はデフォルトで無効になっています。有効にするには、Kubernetes ログ収集を参照してください。

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。

パラメーター
<LOG_CONFIG>{"source": "argo_rollouts", "service": "<SERVICE_NAME>"}

検証

Agent の status サブコマンドを実行し、Checks セクションで argo_rollouts を探します。
