# 使用 EventBridge 監控容量區塊
<a name="capacity-blocks-monitor"></a>

容量區塊保留開始時，Amazon EC2 會透過 EventBridge 發出事件，表示您的容量可供使用。在容量區塊保留結束前四十分鐘，您會收到另一個 EventBridge 事件，通知您保留中執行的所有執行個體將在 10 分鐘內開始終止。如需 EventBridge 事件的詳細資訊，請參閱 [Amazon EventBridge Events](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-events.html)。

以下事件為針對容量區塊所發出事件的結構：
