So a fairly basic report you can make in JSM is how many tickets have been marked as Resolved day by day. You can add some filters to that to get a better breakdown.
But when trying to work out which agent is resolving the most tickets, I can only seem to filter by assignee, who may not be the agent who actually closed the ticket.
Was there any method people are using where their report will show who transitioned the issue to done / who resolved the issue?
Hopefully looking for a solution that only uses the base JSM without add-ons.
