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。

収集データ

Google App Engine 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 App Engine 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 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. 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。
  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。
