I recently came across a nifty app called gtop which shows some really cool information and graphs about your system, such as cpu usage, disk, network, etc in real time.
Here's how I installed it:
sudo apt update sudo apt install npm npm install -g gtop
Then run it with
If you get an error saying "/usr/bin/env: ‘node’: No such file or directory" then try this:
ln -s /usr/bin/nodejs /usr/bin/node
This will symlink it and if you re-run the app it should work!
