We added a USB temperature dongle to our Raspberry Pi and added a shell script that captures the current readings every few minutes. I also tweaked the Supermon page to display the most recent temperature. I’m not sure how this will help you with your VM but I’m happy to share more details.
Most modern x86 platforms already have the hardware to monitor temps. Look for a linux program lm-sensors. You can create a script to call sensors and have links.php in supermon run the script and parse the output for display on the webpage. That’s how I do it
That was understood. I was just sharing our solution to monitor a temperature pulled from a USB dongle and displaying it on the Supermon page. The idea should work on any platform.
