I've got a UCM 7.1.2 system that I'm trying to monitor via SNMP. I'm trying to track the number of registered phones vs. configured phones - so far my first hurdle is trying to get the number of registered phones from the system. According to all the MIBs I can find this is the OID I should use for this:
However if I plug that OID into SNMPGET it tellsm me "No Such Instance currently exists at this OID". I know I've got SNMP configured correctly because I'm able to pull other basic stats like location, CPU %, Disk Space, etc... Any ideas how I can get this info via SNMP?
Actually, I believe in RTMT (real time monitoring Tool) you should be able to setup SMTP alert for when devices become unregistered. CUCM does alert this in RTMT or log files when a number of devices become unregistered. You can set this up to email you when this happens. (MGCP gateways, phones, etc)
