The Stress Terminal UI (s-tui) is a Pretty CPU and Temperature Monitoring Terminal App

While it’s possible to do monitoring with tools like RPI-Monitor on headless or remote systems, top and htop are likely the commonly used tools to monitor CPU and process usage in the terminal. There’s now a new and different option with the Stress Terminal UI that display pretty charts for frequency, CPU usage, and temperature in the terminal, and as its name implies it can also stress the system.

I’ve first installed it in my main computer running Ubuntu 16.04.2 as follows:


and then just started it


It took the screenshot above after enabling stress operation for a few seconds, and while frequency and CPU utilization in percent are updated properly, temperature is not, at least on my system. I had to enable “Smooth Graph” option to see any changes in the first two charts. I tried to run the app again with sudo, but still no temperature update, and that’s because the program is confused since I have two “temp1” values in my machine, one for “it8720” that will always show a constant temperature (45 °C) and one for “AMD CPU” that will vary depending on the load.

A good solution would have to have an option to select the sensor, but there’s no such option for s-tui right now:


I switched to an ARM platform, namely NanoPi NEO board:


So it does not work with Python 3, and requires Python 2.7. Let’s give it another try:


I could install it and run it, but only CPU and temperature charts would be drawn.

The temperature sensor may have not been detected due to the following error:


msr appears to be be something called “model-specific registers”, and only used for x86 CPU, so ARM detection did not work or was not performed here. The developers did test the program successfully with a Raspberry Pi 3 board however. He’s also aware of issues with temperature sensors:

If the temperature does not show up, your sensor might not be supported. Try opening an issue on github and we can look into it

So overall, it’s still work in progress. Support for showing info for multiple cores would be nice, but probably only suitable in a full screen terminal.
