Unresolved incidents of a process instance or a sub process instance are indicated by Cockpit as failed jobs. To localize which instance of a process failed, Cockpit allows you to drill down to the unresolved incident by using the process status dots. Hit a red status dot of the affected instance in the Process Definition View to get an overview of all incidents. The Incidents tab in the Detailed Information Panel lists the failed activities with additional information. Furthermore, you have the possibility of going down to the failing instance of a sub process.
Retry a Failed Job
To resolve a failed job you can use the button on the right side. Select the corresponding instance in the confirmation dialog so the engine will re-trigger this job and increment its retry value in the database.
Please note that this feature is only included in the enterprise edition of the Camunda BPM platform, it is not available in the community edition.
You can also perform a batch retry of failed jobs. This feature is available in the process definition view in the Job Definitions tab. If you hit this button, you will increment the number of retries for all of the defined jobs of the process definition.
