TUI Configuring MySQL-Community-Server: Monitor Your Server Performance with s-tui

Ensuring the optimal performance of your MySQL Community Server is crucial for maintaining efficient database operations. System monitoring plays a vital role in this process, allowing you to identify bottlenecks, optimize resource allocation, and ensure smooth server functioning. While configuring your MySQL server, keeping an eye on system resources can provide valuable insights into the impact of your configurations. This is where terminal user interface (TUI) tools like s-tui become invaluable.

Stress-Terminal UI, or s-tui, is a powerful terminal-based monitoring tool that displays CPU temperature, frequency, power consumption, and utilization in a graphical format directly within your terminal. It’s an excellent resource for anyone configuring and managing a MySQL Community Server, providing real-time feedback on system performance.

Why Use s-tui for MySQL Server Configuration Monitoring?

When you are in the process of configuring your mysql-community-server, you’re likely making changes that can impact system resource usage. s-tui helps you visualize these impacts by:

Real-time CPU Monitoring: Track CPU temperature, utilization, frequency, and power to see how your MySQL server configuration affects processor load.
Performance Dip Detection: Identify performance drops caused by thermal throttling, which can be crucial when stress-testing your MySQL server setup.
Resource Usage Visualization: Graphical representation of resource usage makes it easy to quickly understand system behavior without needing an X-server.
Stress Testing Capabilities: Built-in options to stress the CPU (stress, stress-ng, FIRESTARTER) allow you to simulate high-load scenarios and observe how your MySQL server and system respond.

Getting Started with s-tui

Installation

Installing s-tui is straightforward and can be done through various package managers depending on your Linux distribution.

Using pip (Python Package Installer):

For most systems, pip is the recommended method to get the latest version of s-tui.

pip install s-tui --user

Ensure that ~/.local/bin/ is in your system’s PATH environment variable to run s-tui directly from your terminal.

For system-wide installation:

sudo pip install s-tui

You might need to install python-dev or python3-dev packages beforehand depending on your system.

Installation on Ubuntu:

For Ubuntu 18.10 and later versions:

sudo apt install s-tui

For older Ubuntu versions (18.04, 16.04), a PPA is available, though it might not be the most up-to-date version:

sudo add-apt-repository ppa:amanusk/python-s-tui
sudo apt-get update
sudo apt-get install python3-s-tui

Installation on Arch Linux/Manjaro:

s-tui is available in the Arch repository:

sudo pacman -S s-tui

Installation on OpenSUSE:

sudo zypper install s-tui

Installation on Fedora:

sudo dnf install s-tui

Running s-tui

Once installed, simply execute s-tui in your terminal to launch the monitoring interface.

Navigating the s-tui Interface

The s-tui interface is designed for easy navigation and provides comprehensive system information at a glance.

Sidebar Controls: Use arrow keys or hjkl to navigate the sidebar. This sidebar contains options to control the displayed graphs and monitoring modes.
Modes: Toggle between regular operation and stress testing modes using the radio buttons in the “Modes” section.
Stress Options: Configure stress test defaults in the “Stress options” menu to customize CPU load simulations relevant to MySQL server workloads.
Graph Selection: Choose which graphs to display from the “Graphs” menu, focusing on CPU, temperature, and power when monitoring MySQL server performance.
Summary Selection: Select summaries to display in the “Summaries” menu for a text-based overview of sensor readings.
Reset Button: Use the “Reset” button to clear graphs and statistics for a fresh monitoring session after configuration changes.
UTF-8 Button: Enable smoother graphs if your system supports UTF-8 characters for enhanced visual representation.
Save Settings: Save your current configuration using the “Save settings” button to persist your preferred graph selections and settings.
Quit: Exit s-tui by pressing q or using the “Quit” button.

For command-line options, run s-tui --help.

Utilizing s-tui for MySQL Configuration Optimization

When configuring your mysql-community-server, use s-tui to monitor the impact of different settings. For example:

Buffer Pool Size Adjustments: Observe CPU and memory usage as you adjust the innodb_buffer_pool_size to find the optimal balance for performance without overwhelming system resources.
Query Cache Configuration: Monitor CPU utilization when enabling or disabling the query cache to determine if it’s beneficial for your specific workload.
Connection Limits: Test the impact of max_connections settings on CPU load and temperature under simulated user load to ensure server stability.
Logging Adjustments: Evaluate the CPU overhead of different logging levels and formats to minimize performance impact while maintaining necessary logging for auditing and troubleshooting.

By monitoring these parameters with s-tui, you gain real-time feedback on how your configuration changes are affecting server performance, allowing for data-driven optimization.

Dependencies and Configuration

s-tui relies on psutil for system information retrieval. For stress testing features, the stress package is recommended.

Installing stress (optional but recommended for load testing):

sudo apt-get install stress

s-tui is designed to work out-of-the-box without extensive configuration. However, you can save your preferred settings and even configure custom scripts to run when certain thresholds are exceeded, such as CPU temperature limits.

Saving Configuration:

Clicking in the s-tui interface saves the current settings to ~/.config/s-tui/s-tui.conf. Delete this file to restore default settings.

Threshold Scripts (Advanced):

For advanced users, s-tui allows running custom scripts when thresholds are surpassed. For example, you can create a script named tempsource.sh in ~/.config/s-tui/hooks.d/ to trigger actions when the CPU temperature exceeds a certain limit.

Run from Source Code (For Developers and Advanced Users)

For those who want to contribute or modify s-tui, running from source is an option.

Clone the repository:

git clone https://github.com/amanusk/s-tui.git
cd s-tui

Install dependencies:

[sudo] pip install urwid (--user)
[sudo] pip install psutil (--user)

Run s-tui:

python -m s_tui.s_tui

Compatibility

s-tui is compatible with UNIX-like systems and utilizes psutil, which supports a wide range of hardware. Power readings are supported on Intel Core CPUs (Sandy Bridge and newer) and AMD Family 17h CPUs. It has been tested on Raspberry Pi devices as well.

Conclusion

s-tui provides a valuable TUI-based solution for monitoring system performance while configuring your mysql-community-server. Its real-time graphical interface and stress-testing capabilities make it an excellent tool for optimizing server configurations and ensuring stable, efficient database operations. By integrating s-tui into your MySQL server setup and tuning process, you can gain deeper insights into resource utilization and achieve peak performance.
