Answer 1

My answer is more gui, but still within terminal. Htop may be used with a bit of setup.

1. Start htop.
2. Enter setup menu by pressing F2.
3. From leftmost column choose "Columns"
4. From rightmost column choose the column to be added to main monitoring output, "NLWP" is what you are looking for.
5. Press F10.
