To change the refresh rate from two seconds to 0.1, change the value of Refresh: 2.0 on the sidebar to 0.1, note that this will put extra strain on your Pi. When you first launch S-TUI, it displays all four parameters – Frequency, Utilization, Temperature and Power – and refreshes the data for each every two seconds. For instance, the same information and far more details can be ascertained from running the cat / proc / cpuinfo command. This is because S-TUI uses various other native tools and utilities to gather the relevant information. Our Lenovo test machine was correctly identified as running an Intel Core i3-5005U CPU 2.00GHz processor. Using S-TUIĪt the top of the sidebar on the left are the details about your CPU. Unlike many other command-line utilities, S-TUI requires no configuration and you can begin using it immediately after installation. #Cpu stress test linux installIn the terminal, Update the available software repositories and install the Python 3 packaging tool. For our install we shall use Ubuntu 21.04.ġ. Installing S-TUIĪlthough S-TUI isn’t available in the software repositories of most popular desktop distributions, installing the tool is fairly straightforward, and the project’s GitHub page describes various installation techniques. When coupled with stress, another command-line utility, S-TUI can also be used to stress-test your system. Better still, you can configure S-TUI to automatically launch scripts when the values ââof any of the components being monitored breaches the defined threshold values. The utility presents all the information graphically and can even be used to export the data into CSV files. With S- TUI, which is an acronym for Stress-Terminal UI, you can simultaneously monitor CPU temperature, frequency, power and usage. But if you favor the CLI, like us, you’ll rather enjoy working with S-TUI. Depending on your purpose, you can choose from a variety of dedicated tools to monitor the different components such as CPU frequency, temperature and memory usage. A key matrix for determining the vitality of a Linux distro, or the hardware that it runs on, is system performance.
