How to Install htop on CentOS 8

If you are looking to monitor your system interactively, then the htop command should be one of your best options. An improvement of its predecessor top command, htop is an interactive process viewer and system monitor that displays resource-usage metrics in color and allows you to easily keep tabs on your system’s performance.

It displays information about CPU & RAM utilization, tasks being carried out, load average and uptime. Additionally, htop displays a list of all the running processes and can also display these processes in a tree-like format.

Advantages of htop over top include

  1. Colored output resource usage statistics.
  2. The ability to end or kill processes without typing their PIDs.
  3. Htop allows mouse usage, unlike top which doesn’t support it.
  4. Better performance than top command.

Let’s now jump in and see how to install this handy feature.
