Tracking a Job
...
Submit a Job
A job is submitted via On-Demand or a Trigger Rule. Once submitted it moves to job-queued status.
Job Queued
A queued job is checked to see if its running(?). If it is, the job is moved to job-started status. If not, the job is revoked and changed to job-revoked status. Revoked jobs are then deleted.
Job Started
Running jobs that have been moved to job-started status are checked for two conditions: if they have timed out (via the watchdog check timedout) and if they have succeeded (via the exit code).
If
timedout: Jobs that have timed out are changed tojob-offlinestatus and then deleted.If succeeded with
exit code == 0: Successfully completed jobs are updated tojob-completedstatus. Finally, completed jobs are deleted.If succeeded with
exit code != 0: Jobs with non-zero exit codes are associated with failed jobs. Their status is updated tojob-failedand then deleted.

Job Deduped
...
“In figaro, there are various troubleshooting functions using payload ID to track the job through the system. Include this in the basic flow of jobs through” - Lela
...
Jobs that have identical parameters, or if the same job was already successfully completed, are deduped and no further processing occurs.
Tracking a Job
Jobs can be tracked through the job lifecycle via the payload ID. In Figaro, operators can facet on a job’s unique ID to monitor progression through the various stages as well as for troubleshooting functionality.
Job Completed
The PGE completed successfully.
Job Started
A worker node has started processing a job.
