I'm not sure if it's possible to do using SNMP GET, but you can try using traps.
To configure which event you want to send traps, run evntwin from command prompt.
You just need to know the event ID you want to send traps.
I'm working on it too. Maybe we can help each other. If you want to talk, my MSN is firstname.lastname@example.org
I'm sorry about any English mistakes
