Jobs Events

Jobs publishes to reserved topics on the MQTT protocol when jobs are pending, completed, or canceled, and when a device reports success or failure when executing a job. Devices or management and monitoring applications can keep track of the status of jobs by subscribing to these topics.

Job Completed/Canceled

AWS IoT Jobs publishes a message on an MQTT topic when a job is completed or canceled:

  • $aws/events/job/jobID/completed

  • $aws/events/job/jobID/canceled

The "completed" message contains the following example payload:

{ "eventType": "JOB", "eventId": "7364ffd1-8b65-4824-85d5-6c14686c97c6", "timestamp": 1234567890, "operation": "completed", "jobId": "27450507-bf6f-4012-92af-bb8a1c8c4484", "status": "COMPLETED", "targetSelection": "SNAPSHOT|CONTINUOUS", "targets": [ "arn:aws:iot:us-east-1:123456789012:thing/a39f6f91-70cf-4bd2-a381-9c66df1a80d0", "arn:aws:iot:us-east-1:123456789012:thinggroup/2fc4c0a4-6e45-4525-a238-0fe8d3dd21bb" ], "description": "My Job Description", "completedAt": 1234567890123, "createdAt": 1234567890123, "lastUpdatedAt": 1234567890123, "jobProcessDetails": { "numberOfCanceledThings": 0, "numberOfRejectedThings": 0, "numberOfFailedThings": 0, "numberOfRemovedThings": 0, "numberOfSucceededThings": 3 } }

The "canceled" message contains the following example payload:

{ "eventType": "JOB", "eventId": "568d2ade-2e9c-46e6-a115-18afa1286b06", "timestamp": 1234567890, "operation": "canceled", "jobId": "4d2a531a-da2e-47bb-8b9e-ff5adcd53ef0", "status": "CANCELED", "targetSelection": "SNAPSHOT|CONTINUOUS", "targets": [ "arn:aws:iot:us-east-1:123456789012:thing/Thing0-947b9c0c-ff10-4a80-b4b3-cd33d0145a0f", "arn:aws:iot:us-east-1:123456789012:thinggroup/ThingGroup1-95c644d5-1621-41a6-9aa5-ad2de581d18f" ], "description": "My job description", "createdAt": 1234567890123, "lastUpdatedAt": 1234567890123 }
Job Execution Terminal Status

AWS IoT Jobs publishes a message when a device updates a job execution to terminal status:

  • $aws/events/jobExecution/jobID/succeeded

  • $aws/events/jobExecution/jobID/failed

  • $aws/events/jobExecution/jobID/rejected

  • $aws/events/jobExecution/jobID/canceled

  • $aws/events/jobExecution/jobID/removed

The message contains the following example payload:

{ "eventType": "JOB_EXECUTION", "eventId": "cca89fa5-8a7f-4ced-8c20-5e653afb3572", "timestamp": 1234567890, "operation": "succeeded|failed|rejected|canceled|removed", "jobId": "154b39e5-60b0-48a4-9b73-f6f8dd032d27", "thingArn": "arn:aws:iot:us-east-1:123456789012:myThing/6d639fbc-8f85-4a90-924d-a2867f8366a7", "status": "SUCCEEDED|FAILED|REJECTED|CANCELED|REMOVED", "statusDetails": { "key": "value" } }
