Amazon DynamoDB は、AWS ポートフォリオに含まれる、フルマネージド型 NoSQL データベースクラウドサービスです。スケーリングが高速かつ容易で、大量のデータを扱う場合でもレイテンシーを極めて短く抑える必要があるアプリケーションに対応することができます。ドキュメントストアモデルと key-value ストアモデルの両方をサポートし、データベースと分散ハッシュテーブルの特長を兼ね備えています。
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 DynamoDB が有効になっていることを確認します。
Amazon DynamoDB のメトリクスを収集するために、次のアクセス許可を Datadog IAM ポリシーに追加します。
dynamodb:ListTables: 使用できる DynamoDB テーブルをリストするために使用されます。dynamodb:DescribeTable: テーブルサイズとアイテムカウントに関するメトリクスを追加するために使用されます。dynamodb:ListTagsOfResource: DynamoDB リソースのすべてのタグを収集します。詳細については、AWS ウェブサイト上の DynamoDB ポリシーを参照してください。
Datadog - AWS DynamoDB インテグレーションをインストールします。
AWS CloudTrail で Trail の作成を行い、ログを書き込む S3 バケットを選択します。
All object create events のままにしておきます。ログエクスプローラーに移動して、ログを確認します。
AWS Services のログを収集する方法については、Datadog Lambda 関数で AWS Services のログを送信するを参照してください。
