使用 CloudWatch Events 監控政策

Amazon EBS 和 Amazon Data Lifecycle Manager 會發出生命週期政策動作相關的事件。您可以使用 AWS Lambda 和 Amazon CloudWatch Events，透過程式設計方式來處理事件通知。盡可能發出事件。如需詳細資訊，請參閱 Amazon CloudWatch Events 使用者指南。

可用的事件如下：

注意

AMI 生命週期政策動作不會發出任何事件。

• createSnapshot - 當 CreateSnapshot 動作成功或失敗時發出的 Amazon EBS 事件。如需詳細資訊，請參閱 適用於 Amazon EBS 的 EventBridge。

• DLM Policy State Change—當生命週期政策進入錯誤狀態時發出的 Amazon Data Lifecycle Manager 事件。此事件包含導致錯誤的原因描述。以下是 IAM 角色授予的許可不足時的事件範例。
