Monitoring Bandwidth Usage by IP?

[solomanii]

Hi all,

I am trying to analyse the bandwidth usage by IP address across my home network and looking for a tool that will show this. I am trying to figure out which device is using the most bandwidth so I can figure out why.

Google gave me SurplusUsage but this seems to be discontinued. Open to any suggestions! Prefer something visual but happy to hack around in the terminal too.

Does your router support traffic monitoring by any chance?
A few routers support that. E.g. I have an asus router which has pretty nice visual stats. It looks like this:

The router would be the best, but no it doesn't. I have an airport/time machine that all connections go through but that doesn't seem to have anything like this either.
