RT=Realtime... that's what I thought you meant. The realtime page is the 'activity display' of QueueMetrics, right? I'm not sure what RequestTracker is...
We have an in-house app that's similar to iSymphony but an improved version that's ajax based and better suited to our needs with q-time displayed, call color highlights, drag and drop calls, etc.
I did load the RT page and toggled modes as you suggested but changes to the realtime page didn't seem to affect the Queue Report that I was running.
