I’ve just posted a new report that might be possible, at BigFix/Test Content/Web Reports/dataTables - Action Details Report by Action with Filters.beswrpt at master · Jwalker107/BigFix · GitHub
This one has filters at the top of the page, by default to only show results for actions that are still Open and were issued by a Master Operator. You can add filters or modify these, but with the numbers of action results you’re showing I think the server and browser would struggle to report everything.
With an average of 121 actions reported by each computer, I think you may also want to check into whether you’re cleaning up stopped & expired actions, or how long you should be keeping them before deleting old actions.
