s-tui CPU Monitoring And Stress Testing Tool Sees Its First Stable (1.0.0) Release

s-tui, a terminal-based CPU monitoring and stress testing tool for Linux, has reached version 1.0.0 stable after being in development for almost 3 years.

s-tui monitors the CPU frequency, utilization, temperature, fan speeds and power using colored graphs, while also showing performance dips caused by thermal throttling.

The tool also has built-in options for stress testing the CPU using third party tools like stress or stress-ng. FIRESTARTER is also supported as an external tool for stress-testing the CPU, but do note that you need to install s-tui from source for this, and it doesn't work on all systems.

The TUI (terminal user interface) application has a responsive interface, similar to bandwhich, so the information it shows depends on the size of the terminal window. For the sidebar though, you can use h j k l to navigate it without resizing the terminal window. If you prefer to use the mouse instead of keyboard, you can do that as s-tui has mouse support.
