AWS Batch Events

AWS Batch sends job status change events to EventBridge. AWS Batch tracks the state of your jobs. If a previously submitted job's status changes, an event is invoked. For example, if a job in the RUNNING status moves to the FAILED status. These events are classified as job state change events.

Note

AWS Batch might add other event types, sources, and details in the future. If you're programmatically deserializing event JSON data, make sure that your application is prepared to handle unknown properties. This is to avoid issues if and when these additional properties are added.

Job State Change Events

Anytime that an existing (previously submitted) job changes states, an event is created. For more information about AWS Batch job states, see Job states.

Note

Events aren't created for the initial job submission.

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 AWS Batch API Reference. For more information about EventBridge parameters, see Events and Event Patterns in the Amazon EventBridge User Guide.

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 example blocked job queue messages. 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 AWS Batch API Reference. For more information about EventBridge parameters, see Events and Event Patterns in the Amazon EventBridge User Guide.
