Amazon EC2 Auto Scaling 事件參考

使用 Amazon EventBridge，您可以建立符合傳入事件的規則，並將其路由到目標進行處理。

生命週期動作事件

當您將生命週期掛鉤新增到自動擴展群組時，Amazon EC2 Auto Scaling 會在執行個體轉換為等待狀態 EventBridge時傳送事件至。盡可能產生事件。

橫向擴展生命週期動作

下列範例事件說明了由於啟動 lifecycle hook，Amazon EC2 Auto Scaling 已將執行個體移至 Pending:Wait 狀態。

}

縮減生命週期動作

下列範例事件說明了由於終止 lifecycle hook，Amazon EC2 Auto Scaling 已將執行個體移至 Terminating:Wait 狀態。

重要

當 Auto Scaling 群組在縮減時將執行個體傳回暖集區時，執行個體傳回暖集區也可能會產生 EC2 Instance-terminate Lifecycle Action 事件。在縮減時將執行個體移至等待狀態時，交付的事件會以 WarmPool 作為 Destination 的值。如需詳細資訊，請參閱 Instance reuse policy。

成功的縮減事件

下列範例事件說明 Amazon EC2 Auto Scaling 成功終止執行個體。

重要

當 Auto Scaling 群組在縮減時將執行個體傳回暖集區時，將執行個體傳回暖集區也可能會產生 EC2 Instance Terminate Successful 事件。執行個體成功傳回暖集區時，交付的事件會以 WarmPool 作為 Destination 的值。如需詳細資訊，請參閱 Instance reuse policy。
