    how do I track autocad usage?

    mtnroadking

      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

          I don't know anything about AutoCAD, but in situations like this I'd look first at server resource contention, and second at a full packet capture. NTA isn't going to give you much more than throughput.

            We develop a deep packet inspection system called LANGuardian and I am going to have a look at this traffic in the lab. The main thing I want to check is what our application recognition engine makes of it as it uses different techniques to distinguish between binary and textual protocols. I will publish the results here as they may help you fingerprint the traffic.

              Hi There,

              I ran a quick test here with a Win 7 client (192.168.181.139) running Autocad and the CadWorx overlay. The image below shows what network activity was associated with the client when Autocad and the CadWorx appplications were running.

               

              From an application point of view (1) I did not see anything unusual. Some file share traffic as I saved the drawings out onto a Windows file share which you can see in (2). There is outbound connectivity with the Autocad website (3) and I assume this is to check for updates. If there was a slow down in my case I would be looking at connectivity to the file shares, as you can see below the AutoCad\CadWorx apps create tmp files so if access is slow the apps may suffer.

               

              I did see reference in the CadWorx documentation that you can save data onto SQL databases so if you have this setup you may see activity on the default SQL port (TCP 1433)

                  Darragh,

                   

                  This does explain why we are starting to see degradation in the program. We have hundreds of files all xreffed into a model. If the program then creates temp files as they are working, the system would slow down to some extent based upon the quantity of files being accessed.

                  Thanks for the information.
