SNMP OID

This might get a bit off topic? Sorry in advance if it does...

So I am trying to setup SNMP to monitor pools of these applications. We have this application cluster where there are 25 nodes that are broken down in groups. The app developers have set it up in a way where they decide when nodes the applications run on based on which node they start it on. So I am monitoring all nodes for the applications tomcat port in the application pool and when it comes on line I send that application to it. Not the best way to do it but that's what they want. Anyway, so I don't want to monitor nodes for applications so I am thinking I want to monitor pools, I just want to make sure the pool is up meaning at least one server is listening on that port. Again not the best way to do it but I don't want tons on emails telling me when nodes go into or come out of a pool. Just that the pools is up or down. So I am setting up SNMP, we run the program the Dude but it isn't easy doing the SNMP walk and finding the OID for what you want. It is kind of a guesing game. I am wondering if there is any way to have the F5 tell you this is the OID for blablabla pool. Or is there a program that makes that easy so that I can just find it with that and plug it into the Dude?

Thanks
