We can monitor our system usage by using top command like cpu, memory etc. There is another command which does the similar things like top, but instead of displaying the output in a raw text format, gtop produce a nice graphical output. gtop is based on Node.js. Don’t worry, you don’t need to be a Node.js expert for running gtop,  but for those who are not familiar with the name, Node.js is a JavaScript platform for general-purpose programming that allows users to build network applications quickly. In this tutorial we will see how to install gtop on an Ubuntu 16.04 system.
