Udemy – Linux Performance Monitoring & Analysis – Hands On !! 2025-3

In addition to command-line tools, this course examines software packages such as Sysstat (including the iostat, mpstatand commands pidstat) and SAR (System Activity Reporter), which allow you to collect and analyze system performance data over time. Participants will learn how to schedule tasks using the Systemd timer, as well as use graphical tools such as GNOME System Monitor and Cockpit to monitor systems. An important part of this course is familiarizing yourself with how to configure kernel parameters (Kernel Tunables) through the Proc and Sysfs system files. Students will learn how to change these parameters to improve system performance and apply the changes persistently. Also, managing system resource limits using the command ulimitand configuring persistent rules for these limits will be covered in this course.
