# Amazon Bedrock 是如何 EventBridge 运作的
<a name="monitoring-eventbridge-how-it-works"></a>

Amazon EventBridge 是一个无服务器事件总线，用于接收来自 AWS 服务、SaaS 合作伙伴和客户应用程序的状态变更事件。它根据您创建的规则或模式处理事件，并将这些事件路由到您选择的一个或多个*目标*，例如 Amazon Simple Queue Service 和 Amazon 简单通知服务。 AWS Lambda您可以根据事件的内容配置下游工作流。

在学习如何使用 Amazon f EventBridge or Amazon Bedrock 之前，请查看亚马逊 EventBridge 用户指南中的以下页面。
+ [Amazon 中的事件总线](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-what-is-how-it-works-concepts.html)概念 EventBridge — 查看*事件*、*规则*和*目标*的概念。
+ [创建可响应 Amazon 事件的规则 EventBridge](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-create-rule.html)-了解如何创建规则。
+ [Amazon EventBridge 事件模式](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-event-patterns.html) — 学习如何定义事件模式。
+ [Amazon EventBridge 目标](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-targets.html) — 了解您可以向哪些目标发送事件。

每当你提交的工作状态发生变化 EventBridge 时，Amazon Bedrock 都会通过亚马逊发布你的活动。在每种情况下，都会创建一个新事件并将其发送到 Amazon EventBridge，然后亚马逊会将该事件发送到您的默认事件总线。该事件显示哪个作业的状态发生了更改，以及该作业的当前状态。

在事件中，Amazon Bedrock 事件通过作为 `aws.bedrock` 的 `source` 的值来识别。Amazon Bedrock 中事件的 `detail-type` 包含以下内容：
+ `Model Customization Job State Change`
+ `Batch Inference Job State Change`

选择一个选项卡，查看在 Amazon Bedrock 中提交的作业的示例事件。
