# Service job queue blocked events
<a name="batch-service-job-queue-blocked-events"></a>

Anytime that AWS Batch detects a blocked queue, an event is created in Amazon CloudWatch Events. The reason for the blocked queue is available in the `statusReason` field in the [https://docs.aws.amazon.com/batch/latest/APIReference/API_DescribeServiceJob.html](https://docs.aws.amazon.com/batch/latest/APIReference/API_DescribeServiceJob.html) API action.

**Example Service Job Queue Blocked Event**  
Service job queue blocked events are delivered in the following format. The `detail` section resembles the response that's returned from the [DescribeServiceJob](https://docs.aws.amazon.com/batch/latest/APIReference/API_DescribeServiceJob.html) API operation in the *AWS Batch API Reference*. For more information about EventBridge parameters, see [Events and Event Patterns](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-events.html) in the *Amazon EventBridge User Guide*.  
The `tags` and `serviceRequestPayload` fields are not included in the event `detail`.
