How to send a SNMP alert from Manager

Hi all

I was wondering how I could generate a SNMP alert from Manager, depending on an error’s severity (the error has the status FATAL, or WARNING, for example) and right now, I don’t even know if it’s possible to send a SNMP alert from Manager (the documentation says it’s possible to generate an alert by email, or even with a sound, but says nothing about SNMP …) !

Does anybody know anything about this ?
Thx a lot
