How to identify who takes the most bandwidth?

edit

I have a network with 100 computers connected to 4 different LANs I want to know which computer takes the bandwidth I managed to identify who lan is taking the most of the stripe using the io graph

Now I was left with 30 computers connected to lan with the most traffic I need to create a filter for each ip to identify which ip it is? Or there is a possibility to create a script that will build me 30 filters with ip tracking Like : 10.0.0.1 - blue 10.0.0.2 - Yellow 10.0.0.3 - red

Or is there another possibility?

Thank you
