Amazon Relational Database Service (RDS) は、クラウドでリレーショナルデータベースのセットアップ、運用、スケーリングに使用される Web サービスです。このインテグレーションを有効にすると、Datadog にすべての RDS メトリクスを表示できます。
注: 環境変数 DD_SITE
がコード の外のリージョンに設定されていることを確認するか、または次のようにコードで変数を設定します。
DD_SITE = os.getenv("DD_SITE", default="
")
RDS インスタンスを監視するには、Standard、Enhanced、Native の 3 つのオプションがあります。コンフィギュレーションを選択する前に、メトリクスのリスト全体を確認してください。各メトリクスには対応するコンフィギュレーションのラベルが付いているためです。さらに、以下の情報を確認して、各コンフィギュレーションの要件とプリセットダッシュボードの詳細を確認してください。
標準インテグレーションの場合、AWS インテグレーションページの Metric Collection
タブで RDS を有効にする必要があります。これにより、ご使用の CloudWatch インテグレーションで利用可能な回数だけ、インスタンスに関するメトリクスを受信できます。すべての RDS エンジンタイプに対応しています。
このインテグレーションのプリセットダッシュボードには、接続、レプリケーションラグ、読み取り操作とレイテンシー、コンピューター、RAM、書き込み操作とレイテンシー、ディスクメトリクスのメトリクス情報が含まれています。
拡張インテグレーションの場合、構成を追加する必要があります。また、MySQL、Aurora、MariaDB、SQL Server、Oracle、PostgreSQL エンジンで使用できます。メトリクスを追加することができますが、追加したメトリクスを Datadog に送信するには、AWS Lambda が必要です。粒度が高く、追加のサービスが必要になると AWS の追加料金が発生します。
このインテグレーションのプリセットダッシュボードには、負荷、アップタイム、CPU 使用率、タスク、メモリ、SWAP、ネットワーク受信、ネットワーク送信、プロセスごとに使用される CPU、プロセスごとに使用されるメモリ、ディスク操作、使用されるファイルシステム (pct)、 実行中のタスク、システム CPU 使用率のメトリクス情報が含まれています。
ネイティブデータベースインテグレーションはオプションです。MySQL、Aurora、MariaDB、SQL Server、PostgreSQL の各エンジンタイプで使用できます。RDS とネイティブインテグレーションの両方からメトリクスを取得して照合するには、RDS インスタンスに割り当てる識別子に基づいて、ネイティブインテグレーションで dbinstanceidentifier
タグを使用します。RDS インスタンスには自動的にタグが割り当てられます。
このコンフィギュレーションで使用できるプリセットダッシュボードは、MySQL、Aurora、PostgreSQL の 3 つです。各ダッシュボードには、クエリボリューム、ディスク I/O、接続、レプリケーション、AWS リソースのメトリクスが含まれています。
注: これらのダッシュボードには、AWS CloudWatch と個々のデータベースエンジン自体の両方からのメトリクスが表示されます。すべてのインテグレーションメトリクスに対して、インテグレーション (MySQL、Aurora、PostgreSQL) の 1 つを有効にします。
標準 RDS インテグレーションの場合、最初に Amazon Web Services インテグレーション をセットアップします。
インスタンスの作成中または作成後に RDS インスタンスの拡張モニタリングを有効にするには、Instance Actions の下にある Modify を選択します。監視の詳細度には 15
を選択することをお勧めします。
次の手順では、KMS と Lambda Management Console を使用して、RDS Enhanced Monitoring Lambda 関数でのみ使用できる Datadog API キーの暗号化バージョンを作成します。Log Forwarder などの別の Lambda からの暗号化された API キーを既にお持ちの場合、他のオプションについては Lambda 関数の README を参照してください。
lambda-datadog-key
) を入力します。注: 「aws」で始まるエイリアスは使用できません。「aws」で始まるエイリアスは、ご使用のアカウントで AWS 管理の CMK を表すために Amazon Web Services によって予約されています。Serverless Application Repository
を選択し、Datadog-RDS-Enhanced
を検索して選択します。KMSKeyId
パラメーターに貼り付け、デプロイします。Configuration
タブをクリックし、Environment variables
セクションに移動します。環境変数 kmsEncryptedKeys
の value
フィールドに、以下のように完全な JSON 形式で Datadog API キー を追加します: {"api_key":"<YOUR_API_KEY>"}
Encryption configuration
セクションを開き、Enable helpers for encryption in transit
を選択します。KMS key to encrypt at rest
セクションで、Use a customer master key
を選択し、先に作成したものと同じ KMS キーを入力します。RDSOSMetrics
CloudWatch ロググループをソースとして使用して新しいトリガーを作成します。Lambda 関数のテストボタンをクリックすると、次のエラーが発生する可能性があります。
{
"stackTrace": [
[
"/var/task/lambda_function.py",
109,
"lambda_handler",
"event = json.loads(gzip.GzipFile(fileobj=StringIO(event['awslogs']['data'].decode('base64'))).read())"
]
],
"errorType": "KeyError",
"errorMessage": "'awslogs'"
}
これは無視してかまいません。Test ボタンはこのセットアップでは機能しません。
DB Instance identifier
もメモします (例 mysqlrds)。これはグラフやダッシュボードの作成に使用されます。AWS インテグレーションページで、Metric Collection
タブの下にある RDS
が有効になっていることを確認します。
Amazon RDS 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 RDS ポリシーを参照してください。

数分経つと、RDS メトリクスと MySQL、Aurora、MariaDB、SQL Server、Oracle、PostgreSQL の各メトリクスが Datadog のメトリクスエクスプローラー、ダッシュボード、アラートからアクセスできようになります。
下記に RDS と MySQL 双方のインテグレーションから取得した複数のメトリクスを表示する Aurora ダッシュボードの例を示します。インスタンス quicktestrds
で双方のインテグレーションから取得したメトリクスを dbinstanceidentifier
タグを使用して一つにまとめています。
MySQL、MariaDB、および Postgres のログを Amazon CloudWatch に転送することができます。Amazon CloudWatch で Amazon Aurora MySQL、Amazon RDS for MySQL、MariaDB のログを監視の指示に従って、RDS のログを CloudWatch に送信します。
