Amazon Lambda は、イベントに応答してコードを実行し、そのコードが必要とするコンピューティングリソースを自動的に管理するコンピューティングサービスです。
このインテグレーションを有効にすると、CloudWatch メトリクスが収集されるようになります。このページでは、Lambda 関数のカスタムメトリクス、ログ、トレースを設定する方法についても説明します。
Amazon Web Services 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。
AWS インテグレーションページで、Metric Collection
タブの下にある Lambda
が有効になっていることを確認します。
Amazon Lambda のメトリクスを収集するには、次のアクセス許可を Datadog IAM ポリシーに追加します。詳細については、AWS ウェブサイト上の Lambda ポリシーを参照してください。
AWS アクセス許可 | 説明 |
---|---|
lambda:List* | Lambda 関数、メタデータ、およびタグを一覧表示します。 |
tag:GetResources | Lambda 関数に適用されたカスタムタグを取得します。 |
cloudtrail:LookupEvents | CloudTrail History を使用して Lambda 関数への変更を検出 |
Datadog - AWS Lambda インテグレーションをインストールします。
完了したら、Datadog Serverless ビューにすべての Lambda 関数が表示されます。このページは、サーバーレスアプリケーションを実行している AWS Lambda 関数からのメトリクス、トレース、ログを 1 つのビューにまとめて表示します。この機能の詳細については、Datadog Serverless のドキュメントを参照してください。
AWS から取得される各メトリクスには、関数名やセキュリティグループなど、AWS コンソールに表示されるタグと同じタグが割り当てられます。
