Tool that can show network statistic for each process?

I am looking for a command line tool that can show network statistic for each process. For example, i want to see for the last 24 hours how much traffic each process have received and sent. Is there such a tool?

I don't know of any per-process counters or logging in the network stack. One thing you could do is to match specific ports of interest in iptables and capture its counters periodically.

Check out: https://github.com/raboof/nethogs

Here's a review: https://www.tecmint.com/nethogs-moni...-in-real-time/

I don't use it but the reviews says it provides "real time statistics of your network bandwidth of per process usage".

Hope that helps!

Nethogs is like top in that it shows a realtime display with adjustable update time.
I suspect that it would be possible to capture the output into a log and then graph the usage.
It also seems likely that just setting the update period longer may do what is wanted.

I just installed it from my package manager (dnf) and it seems most of the distros actually have it there for quick install as well. The review posted led me to try the quick install instead of compiling from github.
