Display bandwidth by subnet or groups of VM/Container AND graph summary for all nodes

I like seeing the sum of bandwidth in summary tab. But it would me more than perfect for me to be able to add different graph. On my cluster, I have different sub net (slq cluster, private network, public ip, etc) and it would be great to see individually each bandwidth consumption.

An other idea, why not a simple summary whit graph for all the cluster for CPU,RAM and bandwidth in the same page for monitoring. It would look great on big screen to monitor it!
