Perl : CallManager monitoring script

Hello,

I wrote a Perl script to get the ActiveCall on the CallManager using AXL and XML::Simple. The goal is to supervise the CallManager and get all information like RTMT.

I first start with the active calls (I can also get CallsCompleted, CallsInProgress, etc) and hope to get all other the important information (FXO, MGCP gateway information, active port, etc).

I can get like three counters in a same request if I want, but I don't arrive to extract the result correctly. So I only do one counter per XML request to get the selected result.

I used XML::Simple because I had some trouble using SOAP::Lite with perfmon request. In my script, I do four requests:
  1)Open the session (and get the session ID)
  2)Add the counter
  3)Collect the counter result
  4)Close the session

It's working but I don't know if I¿m doing it correctly and I imagine there is a simple way to get this type of information.
If you have suggestion, ideas or correction, please let me know!
