I have downloaded the Avaya IPO MIB files and I'm sorting through them with the Paessler MIB import tool. It's a little difficult to make heads or tails out of the sensors they have. There are a ton of MIB files and finding useful sensors is like finding a needle in a haystack. Is anyone else monitoring an IPO 500V2 system (R9.0) in PRTG? What sensors did you find useful? I am looking for things like PRI status, PRI lines in use, alarms, etc.
