Reading through supported metrics, I don't see temperatures mentioned. That's really important for homelab servers. CPU temp, SSD temp, NVMe temp...

Temperatures monitoring will be added. Initially, I implemented too many metrics, so during development I limited them to a reasonable level to make them manageable, but I'll be adding more as the project matures. Thanks for the feedback!

Looking forward, thanks!

If you have a moment, I would be grateful if you could create an issue on github. I will then be able to let you know when it's ready and ask you to try it out. Please also let me know which temperatures you'd like to primarily monitor. I assume I'll have to gradually introduce the supported ones, as not all of them can be detected at once.

Most (all?) temperature monitoring tools on Linux rely on libsensors.

Seems like hardware maintainers never could agree on a standard way of exposing temperature on Linux.

Yeah, that's a pain. Every time I boot up new hardware, I wonder how many readings I'll be able to get this time, and if it's even possible. On one computer, I have practically all the temperatures, voltages, and fan speeds, while on another, I can barely read the CPU temperature alone. Not to mention the need to sometimes compile sketchy drivers from github...

Sure thing. In my experiences based on using LibreHardwareMonitor [1] on Windows, and Dunnart [2] on Linux, dealing with temperature monitoring is not trivial. But it's not impossible either. For example, in Linux, looking at /sys folder for CPU temperatures, I can often find several entries, of which, some are dead, some are way off, and some are correct, but it is always a hit and miss endeavour. So, reliably monitoring temperatures requires a bit of an algorithm to detect the right source.

That's true, which is why I assume I'll have to gradually implement this feature. It probably won't be perfect, but it's worth trying :)

Thank you for opening the issue!
