Why not monitor the interface link status?
Or set a threshold on traffic so when inbound traffic is zero you alert.

Hey team, question, is there a way to monitor in a mikrotik with two internet access if both are active? The main link will give us remote snmp access to the equipment but we need to know if there is a way we can verify that the 2nd link that is connected to a DSL modem is up and running.
 
Please advice,
