htop Missing temperature for some threads

I'm using self compiled 3.1.1 release.

On one computer I missing temperature for threads 5-8

In btop++ I see temperature for all cores

For the same CPU on other computer it's all fine

@somera: Can you please provide the sensors -u output?

I have two same NUCs. ;) On the one it's working. On the other not,

Oct 23 '21 18:10 somera

$ lscpu | egrep 'Model name|Socket|Thread|NUMA|CPU\(s\)'

The important line in this:

Thread(s) per core: 2

4 physical processors - four temperature sensors. My chip (Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz) has 5 sensors. One per CPU and one GPU. The built-in GPU is disabled and the temperature sensor is not visible for it. The plasmoid on the desktop shows this picture: Plasma-sensors

Most likely, we need to correctly display the readings of real physical sensors in a separate line, and not mix everything. I.e., for each individual CPU (real \virtual), show the loading slider and frequency, and put the temperature sensors in a separate group.

And now the same issue with the NUC where is works for threads 5-8 ;)

Oct 29 '21 14:10 somera

@somera: This seems to be depending on the sequence of sensors as detected by libsensors. Can you confirm the sensors -u on that computer is different from the one you pasted in the https://github.com/htop-dev/htop/issues/856#issuecomment-950190585 ?

sensors --version sensors version 3.6.0 with libsensors version 3.6.0

Thanks for the information. Your picture shows the truth. I should change 'sensors` to a more up-to-date version.

Dec 09 '21 12:12 The-going

sensors version 3.5.0 with libsensors version 3.5.0

That means, that with

sensors version 3.5.0 with libsensors version 3.5.0

and with

sensors version 3.6.0 with libsensors version 3.6.0

not?

I didn't check this with 3.5.0.

There are 4 physical cores in this processor. There is a temperature sensor on each physical core. Another sensor shows the temperature of the GPU. There are 5 of them in total. In your picture, numbers 5, 6, 7, 8 are virtual cores. They don't have sensors. Your picture shows the truth, and my green one is a lie.
