how do I track autocad usage?

We are using CadWorx which acts as an overlay on AutoCAD. There are times when the designers are having issues with how slow the data is retrieved. I started to look at what ports AutoCAD uses when accessing data but am not able to find much.

I did find that ACAD uses ports 2080 and 27000-27009 for licensing but cannot find much else.

I would like to monitor the application in some way so that we might be able to figure out why it runs slow at some times and OK at others.

We are running AutoCAD 2013 with SP2. Also using CadWorx 2014 Plant Pro and P&ID.

I would appreciate any feedback that others might have.

Thanks
