How does Power Admin for Jira track the group usage?
Power Admin finds all projects associated with a group. The group is part of the configuration of these projects.
Power Admin collects all the permissions, global permission, issue security schemes, events, workflows, agile boards, and filters that use the group. We go through the JQL entries of agile boards and filters and look for references to the group.
The usage information also includes the filters and dashboards a group is accessing and the filters it is subscribed to.
