Htop: user wish: temperature and fan speed meters

[jackyf]

A Debian user would like htop to have temperature + fan speed meters in htop. Full message there: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=776818 .

Thank you for forwarding it! I'm closing it for now (leaving the open issues list only for pending bugs) and marking it with the wishlist status labels (so I can revisit it later).

Hello
Apparently someone wrote a patch implementing temperature readings : https://gist.github.com/bcbnz/f34f61854b4961d1ad66
I haven't tested it though.

That would be great!

Ping on this - hasn't made it into htop 2, maybe 2.01?

[hishamhm]

The problem with that patch is that it spawns a new process on each screen update. A more native solution would be welcome!

:+1: for OSX too

We faced this user wish as well and for my impression it indeed would really fit well into htop on Linux. We found so many 3rd party patched/implementations, but all of them have heavy dependencies and/or are not well implemented into htop (as above).

Many devices safe their temperature info readable inside /sys, but of course the file path/name varies...
Check our method as an idea, at least it covers _some_ devices 😉: https://github.com/Fourdee/DietPi/blob/dev/dietpi/func/dietpi-globals#L802-L809

@MichaIng thanks for the pointer! indeed, the lack of a standardized interface is disappointing. :\

Indeed, looking around a bid, I found lm-sensors to be a popular module, showing (CPU) sensor temperatures. It needs to run a sensor detection command first, which seems to scan/check several different /sys and /proc folders, depending on existent kernel modules, in case enabling modules to access temps: https://github.com/groeck/lm-sensors/blob/master/prog/detect/sensors-detect

Looks quite messy for implementation. Just scanning some most common default locations and provide CPU temp meter just in case one with reasonable output was found, also is not too secure, as users report values of constant 40 °C or simply from other non-CPU sensor.

No problem, if supporting just a limited amount of devices/hardware, but for htop a deal breaker.
