# Amazon Bedrock AgentCore Gateway CloudTrail イベントについて
<a name="understanding-gateway-cloudtrail-log-entries"></a>

「トレイル」は、指定した Amazon S3 バケットにイベントをログファイルとして配信するように設定できます。CloudTrail のログファイルには、ログエントリが 1 つ以上あります。イベントは任意のソースからの単一のリクエストを表し、リクエストされたアクション、アクションの日時、リクエストパラメータなどの情報が含まれます。

**注記**  
データイベントのリクエストとレスポンスの内容は編集され、JSON Web Token (JWT) クレームでは、セキュリティ上の目的で HTML エンティティがサニタイズされます。

**注記**  
管理イベントの場合、Gateway API で定義されたリクエストパラメータのみが秘匿化の対象となります。API の一部ではないリクエストに含める追加フィールドは、送信したとおりに CloudTrail に記録され、編集されません。API の一部ではないフィールドにパスワードやその他の機密情報を含めないでください。

以下のセクションでは、CloudTrail イベントの例を示します。
