Monitor asterisk using SCOM 2012

Hi,

I’m looking for some documentation or even beter a management pack to monitor asterisk activity (number of channels, active calls etc…) from Microsoft system center operations manager 2012.

Has anyone got any experience with doing this? I’ve been trying to get it to work but I don’t seem to have it in me.

Any assistance would be appreciatie

thanks a lot in advance

edit:
forgot t0 add some details…
running asterisk on a CentOS box, which is already monitored by scom 2012 without any issues. So the OS monitoring is under control, is just can’t get it to work with asterisk
