If the status of a job is not known, the Monitoring tool reports the status as UNKNOWN. When the monitoring Model Repository Service restarts or fails over to a backup node, it updates the Monitoring tool with the latest status of each job if the job is still running. The status of a job that completes before the monitoring Model Repository Service becomes available remains as UNKNOWN.

For example, a Data Integration Service runs on a grid. Two mappings are running when the monitoring Model Repository Service fails. The Monitoring tool does not have the latest status of these mappings. One mapping completes successfully before the monitoring Model Repository Service becomes available. The other mapping continues to run after the monitoring Model repository Service becomes available. The Monitoring tool reports the status of the first mapping as UNKNOWN. It shows the status of the second mapping as RUNNING.
