# 服务作业队列阻塞事件
<a name="batch-service-job-queue-blocked-events"></a>

每当 AWS Batch 检测到队列被阻塞时，都会在 Amazon Events 中创建一个 CloudWatch 事件。队列阻塞的原因也会在 [https://docs.aws.amazon.com/batch/latest/APIReference/API_DescribeServiceJob.html](https://docs.aws.amazon.com/batch/latest/APIReference/API_DescribeServiceJob.html) API 操作的 `statusReason` 字段中提供。

**Example 服务作业队列阻塞事件**  
服务作业队列阻塞事件的传输格式如下。该`detail`部分类似于《API *参考*》中从 [DescribeServiceJob](https://docs.aws.amazon.com/batch/latest/APIReference/API_DescribeServiceJob.html)API 操作返回的AWS Batch 响应。有关 EventBridge参数的更多信息，请参阅 *Amazon EventBridge 用户指南*中的[事件和事件模式](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-events.html)。  
`detail` 事件不包含 `tags` 和 `serviceRequestPayload` 字段。
