SNMP Monitoring

[drebo]

I've got a fairly specific application that I'd like to use SNMP to monitor. We have a Cisco AS5400 call gateway acting as a SIP-to-PRI media gateway. I'd like to monitor and table active calls. I have the appropriate MIBs and using an SNMPWalker program, I can confirm that it has the data I want, and I know which OID I need to monitor.

Here's the problem: each active call gets given a sequential instance ID within that OID. As such, my current SNMP monitoring application (Whatsup Gold) is unable to do what I want, as it can only monitor specific instance IDs, and not ALL instance IDs. Within the instance IDs, there is information relating to call duration, calling party, and called party. I would like to tabulate all of that information for all active calls, polled every minute, on a webpage and graph the total number of active calls.

Can anyone think of an SNMP package that would give me the capability to do that without significant programming?

Dumb question - why not use RADIUS accounting? That's specifically what it's for.

Oh, call accounting is handled by a different service already. I just want an easy and concise way to access currently active calls and details about the specific resources they're using on the AS5400 (which DSP the call is running on in addition to which DS1 it's going through and on which channel).

The information is all there in SNMP, I'm just not sure which application gives me the best chance at properly accessing it.

You could try Kiwi CatTools or something from "what's up gold" possibly. I know you can build custom SNMP queries and they're pretty cheap.

Yeah, I've got Whats Up Gold already, but it only supports monitoring specific instance IDs. I'd like to monitor ALL instance IDs (because they're constantly changing). Guess I'll keep looking to see if anyone's done this already.
