I want to show the total traffic for each ISP, and I have 2 or 3 interfaces for each of them. For instance, the first 2 ISPs have 2 interfaces each. I'd like to show the total average traffic (bits in/out on different columns), that would be the addition of the averages (or the aggregated traffic) and not the average of the averages summed up.
I put the Bits in - Total rate column to see if it would do what I expected, but it does not. Instead, it summs up the amount of measures made during the time period selected (Last hour in my case, so 12 measures).
I think it's not wrong as it is designed, but it would be a nice to have feature the possibility to change the behaviour of the value for the group.
