No CPU temperature showing

[wadrie]

Explain what happens

I'm using Cockpit on an Orange Pi 5 running Armbian. I installed the backport versions of cockpit and cockpit-pcp. On the metrics page, there is no CPU temperature showing:

From other Github tickets about this issue I learned that this is useful information: grep -r . /sys/class/hwmon/hwmon*/name /sys/class/hwmon/hwmon0/name:tcpm_source_psy_6_0022 /sys/class/hwmon/hwmon1/name:soc_thermal /sys/class/hwmon/hwmon2/name:bigcore0_thermal /sys/class/hwmon/hwmon3/name:bigcore1_thermal /sys/class/hwmon/hwmon4/name:littlecore_thermal /sys/class/hwmon/hwmon5/name:center_thermal /sys/class/hwmon/hwmon6/name:gpu_thermal /sys/class/hwmon/hwmon7/name:npu_thermal

There is nothing showing in the syslogs about this issue

On ARM we only checkfor cpu_thermal which does not seem like something you have. I am not sure what we should even use here for determing the cpu thermals as it's a Big.Little CPU. I don't see this board being supported yet upstream's u-boot or the Linux kernel so that might explain why the patched kernel uses a different thermal zone.

@jelly Rocky Linux 9 here, running cockpit 276.1 on Intel J1900 (x86-64) I can't see temps aswell:

Am I correct in assuming you mean in other systems something like "/sys/class/hwmon/hwmon1/name:cpu_thermal" exists, and you only check for that value?

If so, maybe an idea would be to make that configurable, so that in my case I could say: use "/sys/class/hwmon/hwmon1/name:soc_thermal" for displaying the temperature. This may be useful for everybody who wants to monitor more than just the CPU temp.

Yes, for arm we check cpu_thermal.

That is misleading the soc thermal isn't the CPU temperature

[wadrie]

OK, bad example, I might use bigcore0_thermal or something like that. My point is, if it's configurable, users can choose themselves if they want just the CPU temp, and what would be the source of that. You could even have multiple so you can monitor the CPU, GPU, SOC, whatever is available in /sys/class/hwmon/

[darmach]

@jelly I have the same issue (no temps displayed) although on different platform (x86-64). Should I open a separate issue? (details of my sensors are posted in previous post)

[jelly]

@darmach I am afraid that you might need to update to 286 or higher as that contains a fix for cpu sensor detection.

[g6avk]

@jelly sadly that fix/update never helped me, as I mentioned in my original BZ https://github.com/cockpit-project/cockpit/issues/18098 Running 292 here, must be something odd with AMD/Ryzen?

[hovancik]

Hi, I am on Debian GNU/Linux 11 (bullseye) aarch64 and I also do not see the temperature. Raspberry Pi 4 B.

grep -r . /sys/class/hwmon/hwmon*/name
/sys/class/hwmon/hwmon0/name:cpu_thermal
/sys/class/hwmon/hwmon1/name:rpi_volt

grep -r . /sys/class/hwmon/hwmon*/temp*
/sys/class/hwmon/hwmon0/temp1_crit:110000
/sys/class/hwmon/hwmon0/temp1_input:53556

[jelly]

@hovancik and which Cockpit version?

[hovancik]

@jelly ah, nevermind my question, I see I have some super-old version 239 https://packages.debian.org/bullseye/cockpit. sorry for bother
