I need to create an alarm when the sum of the traffic of a group of interfaces is zero (or very low). We have some ISPs and for each of them we have 2 interfaces connected. One interface is active and the other is passive, but they are not part of a port channel. So, one of them traffics around 300-500mbps and the other one is around 10kbps (control only).
Is it possible to create a threshold profile to alarm in case one ISP's traffic falls?
