概要

Google Cloud Pub/Sub は、エンタープライズメッセージ指向ミドルウェアの拡張性、柔軟性、信頼性をクラウドにもたらします。

Google Pub/Sub からメトリクスを取得して、以下のことができます。

  • Pub/Sub のトピックおよびサブスクリプションのパフォーマンスを視覚化。
  • Pub/Sub のトピックおよびサブスクリプションのパフォーマンスをアプリケーションと関連付け。

セットアップ

メトリクスの収集

インストール

Google Cloud Platform インテグレーションをまだセットアップしていない場合は、最初にセットアップします。それ以上のインストール手順はありません。

構成

カスタム Pub/Sub ラベルをタグとして収集するには、Cloud Asset Inventory のアクセス権を有効にします。

収集データ

Google Cloud Pub/Sub のログは Google Cloud Logging で収集され、Cloud Pub/Sub トピックを通じて Dataflow ジョブに送信されます。まだの場合は、Datadog Dataflow テンプレートでロギングをセットアップしてください

これが完了したら、Google Cloud Pub/Sub のログを Google Cloud Logging から Pub/Sub トピックへエクスポートします。

  1. Google Cloud Logging のページに移動し、Google Cloud Pub/Sub のログを絞り込みます。

  2. シンクを作成し、シンクに適宜名前を付けます。

  3. 宛先として “Cloud Pub/Sub” を選択し、その目的で作成された Pub/Sub トピックを選択します。: Pub/Sub トピックは別のプロジェクトに配置できます。

    Google Cloud Pub/Sub ログを Pub Sub へエクスポート
  4. 作成をクリックし、確認メッセージが表示されるまで待ちます。
