In this tutorial, we will show you how to install Htop on Rocky Linux 9. For those of you who didn’t know, Htop is an interactive process manager and viewer for system monitoring. It is just like the default top command with an additional set of options and a better display on the monitor. Htop displays a frequently updated list of the processes currently executing on a computer, usually in the order of CPU consumption.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Htop interactive process viewer on Rocky Linux. 9.
