This would be very helpful to determine if a particular job, user, or pool is under/over utilizing the capacity, if we need more capacity, what time slots have holes, etc. I'll see if I can create an example in Excel of what I'm thinking of. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
