Google Pub/Sub

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 のトピックとサブスクリプションのパフォーマンスを視覚化できます。
  • Pub/Sub のトピックと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ることができます。

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。

ログの収集

Google Cloud Pub/Sub のログは、Stackdriver を使用して収集され、HTTP プッシュフォワーダーを使用して Cloud Pub/Sub へ送信されます。Cloud Pub/Sub をまだセットアップしていない場合は、HTTP プッシュフォワーダーを使用して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 Stackdriver から Pub/Sub へエクスポートします。

  1. Stackdriver のページに移動し、Google Cloud Pub/Sub のログを絞り込みます。
  2. エクスポートを作成をクリックし、シンクに適宜名前を付けます。
  3. エクスポート先として「Cloud Pub/Sub」を選択し、エクスポート用に作成された Pub/Sub を選択します。: この Pub/Sub は別のプロジェクトに置くこともできます。
  1. 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。
