QOTD: Hello Linux users, what do you use to monitor your network traffic?

As you can see in most of my screenshots, I have a widget at the top of my screen that shows the current bandwidth usage:

But what does that tell me? What do I do when I see a sudden spike and I don’t know where it’s coming from? 🤔 I don’t have an answer for that. I’d like to have something like a summarized log of the recent network activity of all processes.

Something like tcpdump doesn’t help here, because the traffic is often already finished when I notice it.

@movq@www.uninformativ.de You could always keep it running in a detached tmux session and attach it when you see the spike. Processes that were recently using the netwotk stay in the list for 10 or 15 seconds after they’re finished so you don’t have to catch it in the act.

@movq@www.uninformativ.de It’s very useful. I always start my music player in a tmux session so I can SSH in, attach it, and control the music from another computer. It’s also handy for letting long-running tasks on a remote machine continue in the background even if the SSH connection is broken.
