テレメトリ機能

このトピックでは、Juniper Cloud-Native Routerから利用できるテレメトリデータについて説明します。

Cloud-Native Routerテレメトリ

Juniper Cloud-Native Routerにはテレメトリ機能が搭載されており、パフォーマンスメトリクスやテレメトリデータを確認できます。テレメトリデータは、vRouterおよびcRPDから別々に取得されます。コンテナ contrail-vrouter-telemetry-exporter は、Prometheus ベースの API または gRPC ネットワーク管理インターフェイス(gNMI)を介して、この可視性を提供します。このコンテナは、 contrail-vrouter-masters ポッド内の他の vRouter コンテナと一緒に実行されます。テレメトリエクスポーターは、デフォルトでvRouterとcRPDの両方で有効になっています。values.yaml で次のスニペットを使用して、テレメトリを構成できます。

PrometheusベースのAPI経由のテレメトリ

Prometheusは、オープンソースのシステム監視およびアラートツールキットです。Prometheusを使用して、Cloud-Native Routerのホストサーバーからテレメトリデータを取得し、そのデータをHTTP形式で表示することができます。Prometheus の構成例は、次のようになります。

vRouterの場合、テレメトリエクスポーターは、vRouter-agentのIntrospectに統計情報を定期的に照会し、Prometheusスクレイピングリクエストに応答してメトリック情報を報告します。テレメトリ データは、 URL http://host server IP address:8070 を使用して直接表示できます。

cRPDテレメトリエクスポーターは、定期的にcRPDのNETCONFに統計情報を照会し、Prometheusスクレイピング要求に応答してメトリック情報を報告します。テレメトリ データは、 URL http://host server IP address:8072 を使用して直接表示できます。

手記：

8072 ポートが使用できない場合は、values.yaml でテレメトリ データを収集する代替ポートを選択できます。

以下の表は、Prometheus ベースの API を使用する場合の vRouter と cRPD のテレメトリ出力の例を示しています。

手記：

次の表に示す出力をグループ化しました。Cloud-Native Routerは、ライブシステム上の出力をグループ化またはソートしません。

gNMI経由のテレメトリ

gNMI プロトコルは、テレメトリ データにサブスクライブするための Subscribe RPC を定義します。テレメトリコレクターは、このRPCを使用して、状態と設定データの更新をネットワークデバイスに要求します。詳細については、 gNMI を使用したテレメトリデータのサブスクライブ を参照してください。

values.yaml Helm チャートで gNMI 設定を有効にすることで、サポートを有効にできます。詳細については、お使いのプラットフォームの Helm チャートのカスタマイズ のトピックを参照してください。JCNR のインストール時に helm install コマンドに次の引数を渡すことで、gNMI を有効にすることもできます。

手記：

  1. helmchart で telemetry.gnmi.enable が true に設定されている場合、外部クライアントは grpc ポート 50053 に接続できます。

  2. gNMI サブスクリプションは、次のような外部クライアントからの認証済み要求でのみ機能します。

  3. SAMPLE および TARGET_DEFINED サブスクリプションモードは、現在のリリースでサポートされています。

  4. パスのキー値を使用した SubscribeMessage 内の特定のインスタンスのターゲット設定は、現在のリリースではサポートされていません。例えば、などのパスを使用して特定のインターフェイスのメトリックを監視することをサブスクライブすると、 /interfaces/interface[name=”enp3s0”]/state/counters

  5. gNMI デバッグ ログは、 /var/log/jcnr/na-grpcd から入手できます。

次の表に、テレメトリ メトリックでサポートされているセンサーを示します。
