Monitoring the real-time state and behavior of the system and each of its components is crucial for any system administrator. Guider is an open-source performance analyzing tool for Linux operating systems. It is designed to measure the use of system resources, analyze it and improve the performance of the operating system.
In this tutorial, I will show you how to install and use Guider on Ubuntu 20.04.
Prerequisites
- A server running Ubuntu 20.04.
- A root password is configured on your server.
Install Guider
Guider is a Python-based tool so you will need to install Python and PIP to your system. You can install both using the following command:
apt-get install python3 python3-pipOnce both packages are installed, install the Guide by running the following command:
pip3 install --pre guiderOnce installed, verify the version of Guider with the following command:

Set Guider Buffer Size
Guider uses buffer size to perform all operations. The default buffer size is very low. You can check it with the following command:
cat /sys/kernel/debug/tracing/buffer_size_kbYou should see the following output:
7 (expanded: 1408)
It is recommended to set it to the required values. You can set the value to 40960 with the following command:
echo 40960 | tee /sys/kernel/debug/tracing/buffer_size_kbHow to Use Guider
Before starting, list all options available with Guider using the following command:
guider --helpYou should see the following output:
/ G.u.i.d.e.r ver.3.9.8 /

To generate a complete system analysis report including, system info, OS info, CPU info, memory info, and disk info, run the following command:
guider rec -a -e mYou should see the following screen:
To trace the system and save the data in a file, run the following command:Advertisement
guider top -o .The above command will save the data in a file guider.out.
You can inspect it with the following command:
cat guider.outConclusion
In the above guide, you learned how to install and use the Guider System Performance Analysis tool on Ubuntu. I hope this will help you to analyze the operating system usage and give an idea to improve the performance.
