How to Install Guider Linux Performance Analyzer on Ubuntu 20.04

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-pip

Once both packages are installed, install the Guide by running the following command:

pip3 install --pre guider

Once installed, verify the version of Guider with the following command:

guider

You should get the following output:

   _____       _     _
  / ____|     (_)   | |

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_kb

You 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_kb

How to Use Guider

Before starting, list all options available with Guider using the following command:
