Network usage breakdown #21

Looks like a great start!

My two cents: Something that is currently missing from all GUI system monitors in Linux (but exists at a limited level in Win10) - a real, working and useful network usage breakdown:

  1. Per process (matching the current process list)
  2. Per process group (e.g., container)
  3. Per connection target (e.g., "facebook.com")

Also, a display of all registered sockets/handles (lsof style) in their current state, broken down to process or target, would be very useful.

Thank you for your comment!

There will be definitely a redesign of the process tab! This tab could be so much more useful than it is right now and I think your ideas would be a great addition.

These ideas are great and useful, but the Linux kernel doesn't store the process-wise network information. To show the process-wise network activity nethogs can be used which basically monitors every process and check how much data is the process receiving and sending. This indeed works good but is a heavy workload on CPU. This project https://github.com/rejuce/LikeTaskManager does use nethogs. So it for low end machine this approach is not suitable.
