How To Install Nmon on Ubuntu 22.04 LTS

In this tutorial, we will show you how to install Nmon on Ubuntu 22.04 LTS. For those of you who didn’t know, Nmon (Nigel’s performance Monitor) is a popular performance monitoring tool for Linux operating systems. It provides an overview of the system performance, including system statistics such as CPU usage, memory usage, disk I/O activity, network traffic, and more. Whether you are a system administrator or a performance analyst, Nmon is a valuable tool to have in your toolkit.

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 Nmon monitoring tool on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

• SSH access to the server (or just open Terminal if you’re on a desktop).
