Job queue blocked events

Anytime that AWS Batch detects a job in the RUNNABLE state and thus blocking a queue, an event is created in Amazon CloudWatch Events. For more information about supported blocked queue causes, see Jobs stuck in a RUNNABLE status. The same reason is also available in the statusReason field in the DescribeJobs API action.

Example Job queue blocked event

Job queue blocked events are delivered in the following format. The detail section resembles the JobDetail object that's returned from a DescribeJobs API operation in the AWS Batch API Reference. For more information about EventBridge parameters, see Events and Event Patterns in the Amazon EventBridge User Guide.
