How To Install SysStat on Ubuntu 20.04 LTS

Install SysStat on Ubuntu 20.04

In this tutorial, we will show you how to install SysStat on Ubuntu 20.04 LTS. For those of you who didn’t know, Sysstat is a free and open-source system monitoring tool. This is the best tool I found for debugging performance issues on my Linux systems. You can view the system performance data in real time or analyze data from the saved archives.

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 SysStat monitoring tool on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.


  • A server running one of the following operating systems: Ubuntu 20.04, 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install SysStat on Ubuntu 20.04 LTS Focal Fossa

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

Step 4. Realtime Monitoring Using Sysstat.

Once successfully installed, you can get a real-time system static command-line tool. Below are some about various static to view on the command line:

  • iostat – shows an overview of CPU and I/O statistics for drives and partitions
  • mpstatdisplays processor statistics.
  • pidstat – gives an overview of I/O, memory statistics for processes.
