I'm trying to monitor the utilization of what will eventually be over 20 PRIs. In version 4.x of call manager we used windows perfmon to watch the channels in use then dumped that information out to a .txt file that was parsed and graphed to give a historical view. We recently upgraded to CM6.x and lost the ability to pull this information out of perfmon. I've looked at a number of OIDs - some of which looked promising but recently found CISCO-POP-MGMT-MIB:cpmDS1ActiveDS0s isn't reliable on the 2801 / 2821 platforms we use. Where we have the pri installed in 0/0/0 we MIGHT get accurate results but where the PRI is in other controllers we generally get 0 returned or OID not supported. Has anyone found a good way to pull back this information either from gateways or the call managers themselves?
