Effective system monitoring is vital for any system administrator to maintain optimal performance. Guider is an open-source tool designed for Linux systems to monitor and analyze system resource usage, offering insights to improve performance.
This tutorial will guide you through the installation and usage of Guider on Ubuntu 20.04.
Prerequisites
- A server running Ubuntu 20.04.
- Root access with a configured password on your server.
Installing Guider

Configure Guider Buffer Size
Guider’s default buffer size might be too small. You can verify it with:
cat /sys/kernel/debug/tracing/buffer_size_kb
The output will appear as:
7 (expanded: 1408)
To enhance performance, set the buffer size to 40960:
echo 40960 | tee /sys/kernel/debug/tracing/buffer_size_kb

You can track real-time Memory, CPU, and Swap usage by:
guider ptop -g yes
For real-time network monitoring, use:
guider ntop
To obtain systemd related details, execute:
guider printenv -g systemd

To generate a comprehensive system analysis report, run:
guider rec -a -e m
To trace the system and save it to a file, execute:
guider top -o .
This command saves the data to a file named guider.out. You can view it using:
cat guider.out
