Overview

The History list (ops_history) provides an historical display of all completed task activity. Only task instances with a status in an "end state" (SUCCESS, FINISHED, FAILED, CANCELLED, START FAILURE, SKIPPED) display in the History list.

The list allows you to track information about specific task instances, including multiple runs. For example, Task A may have failed and then was re-run by a user. This task instance will display twice on the History list, first for the time that it ran and failed and again for the time it was re-run to success.

Note

If you want to display task activity for all tasks, for task instances in any status, and issue commands against those task instances, see the Activity Monitor and/or Task Instances list

If you want to display task activity for a specific task, for task instances in any status, and issue commands against those task instances, see the Viewing Task Instances for a Specific Task.
