[Observium] Alert for port-channel summary?

Hello,

We have Cisco Nexus switches with VPC configuration. On the switches are configured a portchannel (in VPC with 2x10G ethernet) to the same 3. device.

The problem is: I would like to create an alert if the traffic to the 3. device more than 8G I have to get an alert. Now because the 2 nexus just show only the own port-channel traffic, if one portchannel traffic on switch#1 is 6G and on the switch#2 is 5G the 8G alert doesn’t work. But because of the redundancy in this case I have to get an alert because the aggregated traffic is 11G (and if one of the 10G goes down this traffic is overloaded).

The alert is:

Test: ifOutOctets_perc gt 80 Device Match / Entity Match Hostname match *switch* ifAlias match *to 3. device*

So it cover the switch#1 and switch#2 and the port-channel interfaces with description “2x10G to 3. device” but this alert check the port-channels like a line not an aggregated traffic.

Is there any option to add two device’s interfaces and create an alert for this summary?

Or can I create an alert for a port group aggregated traffic? This would be great in this case too.

Thanks
