[Observium] monitor specific ports

Hey guys, i am trying to monitor two things in a port, if is operational up with “ ifOperStatus notequals up” but if I set it up to all my switches, it sends 2221 (literally) emails regarding all the ports available in my networks. How can I specify certain ports in certain devices.

The other one is to be able to see if there is “traffic”, the scenario is we have a several mikrotik devices connected to DSL modems, but we need to see if the DSL service is up and running and get a notification if this port / service goes down.

Regards,

Luis
