Hi, There is already a project for monitoring SNMP: http://snmpjmeter.sourceforge.net/ which does a lot of what I was going to do.
I basically isolated a handful of OID's, and was going to allow configuration of monitored resources based on this. I may still finish off SNMP plugin if the existing project doesnt meet our needs. Differences between what i have so far and the existing one: 1. mine can currently accept custom community string (and easy to adapt for v3 snmp) 2. can select which resource to monitor: mem / swap, cpu and load parameters. 3. started working on snmpwalk type funtionality. feedback on this?
