Hello,
I am running SCOM 2012 R2 and I have SNMP traps configured with an SNMP Event Collection. When certain events come in, they can be read. For example, if I Telnet into a switch, the event will read TELNET from 111.111.111.111. But if the alerts is "Port 37 blocked by STP", the event comes in as "37". That's it. No date, Time, level, etc. Just the port number.
