Install Sysdig on Debian 11

In this tutorial, we will show you how to install Sysdig on Debian 11. For those of you who didn’t know, Sysdig is an open-source, cross-platform system monitoring and troubleshooting tool. It provides a complete overview of the usage of CPU, Memory, IO, users, and more directly on the command terminal in a well-structured interface also gives us a ton of insight into what actually happens on our servers, containers, or desktops during normal operations.

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 through the step-by-step installation of the Sysdig monitoring on a Debian 11 (Bullseye).

In the picture above, you will see columns like PID, Name, CPU, and Comm. These are column descriptions and can be seen by hovering your mouse over them. The syntax of column names is [field name]- [field descriptor].

The fields we care about most usually include:

  • PID – the PID of the process which generated the event.
  • PPID – the PID of the parent process for a given process.
  • %CPU – how much CPU time a process is using.
  • USER – the username of the user responsible for the process.
  • RES – the amount of non-swapped memory a process is using.
  • Command – the command line that started the process.
