# Amazon Bedrock 的 EventBridge 運作方式
<a name="monitoring-eventbridge-how-it-works"></a>

Amazon EventBridge 是一種無伺服器事件匯流排，可從 AWS 服務、SaaS 合作夥伴和客戶應用程式擷取狀態變更事件。它會根據您建立的規則或模式處理事件，並將這些事件路由到您選擇的一或多個*目標*，例如 AWS Lambda Amazon Simple Queue Service 和 Amazon Simple Notification Service。您可以根據事件的內容來設定下游工作流程。

在了解如何使用 Amazon EventBridge for Amazon Bedrock 之前，請參閱《Amazon EventBridge 使用者指南》中的下列頁面。
+ [Amazon EventBridge 中的事件匯流排概念](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-what-is-how-it-works-concepts.html) – 檢閱*事件*、*規則*和*目標*的概念。
+ [建立對 Amazon EventBridge 中的事件做出反應的規則](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-create-rule.html) – 了解如何建立規則。
+ [Amazon EventBridge 事件模式](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-event-patterns.html) – 了解如何定義事件模式。
+ [Amazon EventBridge 目標](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-targets.html) – 了解您可以傳送事件的目標。

每當您提交的任務狀態發生變更，Amazon Bedrock 即會透過 Amazon EventBridge 發布您的事件。在每一種情況下，都會建立新事件並將其傳送至 Amazon EventBridge，然後將事件傳送到您的預設事件匯流排。此事件會顯示哪些任務的狀態已變更，以及工作的目前狀態。

Amazon Bedrock 事件在事件中是透過 `source` 的值為 `aws.bedrock` 來識別的。Amazon Bedrock 中事件的 `detail-type` 包含下列項目：
+ `Model Customization Job State Change`
+ `Batch Inference Job State Change`

選取索引標籤以查看在 Amazon Bedrock 中提交之任務的範例事件。
