}

data欄位包含的參數解釋如下表所示。

參數	類型	樣本值	描述
instanceIds	Array	[ "i-xxx" ]	縮容執行個體ID列表。
lifecycleHookId	String	ash-xxx	生命週期掛鈎ID。
lifecycleActionToken	String	XXXX	伸縮活動的等待狀態標識符。
scalingGroupId	String	asg-xxx	伸縮組ID。
scalingActivityId	String	asa-xxx	伸縮活動ID。
notificationMetadata	String	lifecycleHook metadata example	生命週期掛鈎通知資訊。
defaultResult	String	CONTINUE	生命週期掛鈎預設結果。取值如下： CONTINUE：繼續響應彈性擴張活動或者繼續響應彈性收縮活動。 ABANDON：直接釋放彈性擴張活動建立出來的ECS執行個體或者直接將彈性收縮活動中的ECS執行個體從伸縮組移除。 ROLLBACK：針對彈性收縮活動，會拒絕釋放ECS執行個體，進行復原；針對彈性擴張活動，會直接釋放建立出來的ECS執行個體，效果同ABANDON一樣。
