I'm not sure how it works beyond that it reads /proc, but whatever it does it uses a whole lot more compute than nethogs does (which also displays per process and also uses /proc as the information source). This is fine for most of my machines, but for lower-specced machines I'll probably have to stick with nethogs[1] [1]: https://github.com/raboof/nethogs. - Source: Hacker News / 9 months ago

Nethogs(rpm) is a much simpler solution. It's also available on the repos. Source: over 1 year ago

Ngrep is ok, I just use nethogs, nmap and tcpick, and tcpdump with termshark for most network analysis. Source: over 1 year ago

Hello. I'm running linux mint at the moment. And I use a program that check the network sometimes that's called nethogs. https://github.com/raboof/nethogs. Source: about 3 years ago

I think nethogs might do this if I'm looking at the screenshot properly. Bandwhich appears to show what's being connected to on a per-process basis. Source: about 3 years ago

My favorite that fits your request is SpeQ Mathmatics. For rolling dice use the command RandInt (random integer) along with the lowest and highest values. For your RGB example you would enter (RandInt( 1,255 ), RandInt( 1,255 ), RandInt( 1,255 )). Pressing F5 generates a new set of results. Source: almost 2 years ago
