How to use Guider

In Guider, the buffer size is set for its operations by default. the buffer size can be seen by using the following command:

sudo cat /sys/kernel/debug/tracing/buffer_size_kb

If the value is found to be less than 40960, then we have to set it to the required value using the following command:

echo 40960 | sudo tee /sys/kernel/debug/tracing/buffer_size_kb

Guider is an open-source integrated performance analyzer tool written mostly in Python for Linux operating systems. Most of the functions required for measuring, analyzing, testing, and verifying Linux system performance are provided in Guider. Guider provides most of the features like  Monitoring, Profiling, Visualization,  control, Logging, Test. 

Information concerning CPU, memory, disk usage per thread, processes, system functions (user/kernel) are shown which makes it easy to know the root cause for abnormal system performance and improve them.

In this article, the installation of guider from source will be shown and also how to use it to analyze and improve overall Linux operating system performance.
