One way to do this would be to define unique Subsystem IDs for the processes probe alarm in the nas (for example a Subsystem ID for system process alarms and one for application process alarms). Then for each of your profiles in the processes probe that correspond to a system process, define the alarm and clear alarm in the profile and use the corresponding Subsystem ID you created in the nas probe for the system processes. You would do the same for each of your application process profiles using the Subsystem ID you created in the nas probe for the application processes.
Once you have this in place, then you can create Auto-Operator profiles in the nas which will email the alarm to the appropriate group based on the subsystem ID of the alarm message from the processes probe.
