Command-line tools like “top” make it difficult to see CPU usage across multi-process applications (like Apache and Chrome), spikes over time, and memory usage. Vtop is a free and open-source activity monitor for the command line. It’s written in node.js and can be easily extended.
How to install
If you haven’t already got Node.js, then download that first, then run:
sudo npm install -g vtop
Running
This is pretty simple too.
vtop
It is quite a cool application to have in our tool chest.
