Google App Engine

Crawler Crawler

概要

Google App Engine インテグレーションをプロジェクトにインストールして、以下のことができます。

  • Google App Engine サービスのメトリクス (メモリキャッシュ、タスクキュー、データストア) を確認できます。
  • リクエストに関するメトリクス (表示パーセンタイル、レイテンシー、コスト) を確認できます。
  • Google App Engine のメトリクスをバージョンごとにタグ付けし、異なるバージョンのパフォーマンスを比較できます。

また、APIDogStatsD を使って、Datadog にカスタムメトリクスを送信することも可能です。

セットアップ

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 App Engine のログは Google Cloud Logging により収集され、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。HTTP プッシュフォワーダーを使用した Cloud Pub/Sub をまだセットアップしていない場合は、これをセットアップしてください。

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

  1. Google Cloud Logging のページに移動し、Google App Engine のログを絞り込みます。
  2. Create Export をクリックし、シンクに名前を付けます。
  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内に配置することもできます。
  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。
