Job queue blocked events - Amazon Batch
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Job queue blocked events

Anytime that Amazon 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 State Change Event

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