advice on collecting and manage windows performance alerts in OME

Hi all, i would like to configure OME to collect data from Windows performance monitor alerts I use the embedded event viewer to SNMP utility to send logged events in the application log via SNMP to OME. It works but the trap is unknow type as the OID is not defined. I can define my own trap in MIB import utility but in that way i must create a custom trap for every alert... Am i right? I wonder if there was a short way to do the job, like create my own MIB and import via MIB utility Thanks, Mauro
