No temperature data on Thermal Sensor widget after upgrade to 20.7.1

[lore.phoenix]

Hello,

My OPNSense system has the CPU type: Intel(R) Core(TM)2 Duo CPU E6850 @ 3.00GHz (2 cores)

Before I upgraded to OPNSense version 20.7 I was able to see the temperature at the Thermal Sensors widget on my OPNSense (v20.1.9) dashboard.
After the upgrade I waited serveral hours but the Therminal Sensors widget on my OPNSense (v20.7.1) dashboard doesn't display anything.

I checked under Reporting -> Health -> System -> Cputemp and the Cputemp graph is able to display the temperature.

The actions I already took :
1.  After that I set the Thermal Sensor under System -> Settings -> Miscellaneous to None/ACPI.
    I rebooted the server.
2.  I enabled the Thermal Sensors under System -> Settings -> Miscellaneous to
    Hardware : Intel Core* CPU on-die therminal sensor (coretemp).

    On the CLI I saw the following message appearing:

   

Code Select Expand

# coretemp0: <CPU On-Die Thermal Sensors> on cpu0
    est: CPU supports Enhanced Speedstep, but is not recognized.
    est: cpu_vendor GenuineIntel, msr 92a092a0600092a
    device_attach: est1 attach returned 6

   

Code Select Expand

# sysctl -a | grep temperature
    dev.cpu.1.temperature: 35.0C
    dev.cpu.0.temperature: 32.0C

3. After 15 ~ 20mins I was able to see new Cputemp graphs under Reporting -> Health -> System -> Cputemp but the Thermal Sensor widget still doesn't display anything.

4. I removed the Thermal Sensor widget from my dashboard and re-add the Thermal Sensor widget on my dashboard but the result is the same (meaning no data).

Since I am able to read the temperature using the CLI command 'sysctl -a | grep temperature' and able to get the Cputemp graph under Reporting -> Health -> System -> Cputemp that I assume that the problem is related on the Thermal Sensors widget.

Is it possible to fix this ??

Kind regards,

Hi everyone,

Same issue as lore.phoenix (not showing anything on the widget), except that on Reporting -> Health -> System -> Cputemp, it does show only one graph from cpu0temp, whereas my router have 4 cores

Code Select Expand


sysctl -a | grep -E "dev.*temperature|hw.*temperature"
hw.acpi.thermal.tz1.temperature: 29.9C
hw.acpi.thermal.tz0.temperature: 27.9C
dev.cpu.3.temperature: 51.0C
dev.cpu.2.temperature: 51.0C
dev.cpu.1.temperature: 50.0C
dev.cpu.0.temperature: 50.0C


but not such error on system.log as shown by lore.phoenix

I am new to freeBSD and opnsense (i did not do any update, it an install from scratch), i will try to search for any error but any help would be great :)

have a good day

Click the pencil on the temp widget, there's a check box in the widget settings for all or single core.

Just for what it is worth, I stumbled across this. I just updated last night. I'm still seeing the temps. I'm using: Intel(R) Celeron(R) CPU J3160 @ 1.60GHz (4 cores)

Many thanks Marjohn56! I have done a factory reset of the bios settings + re-activating core temp + done what you suggested, and it did work well ! :)

For reference, I have a mini pc Qotom with 6 LAN ports and i3-6100u cpu

thanks again for your quick help and have a nice day

I tried what marjohn56 suggested but that didn't work for me.
It was disabled but even enabling the option 'Only show first found CPU core temperature' didn't display anything.

@chukkyuggets
After my BIOS reset + reactivating core temp that it fixed my issue. Many thanks for your input/solution.


My hardware:
Motherboard: Gigabyte P35-DS3R
Processor: Intel(R) Core(TM)2 Duo CPU E6850 @ 3.00GHz (2 cores)

A little confused. Why is a BIOS reset required to get the thermal data showing again after the 20.7 upgrade?

I'm not even sure how I perform a factory reset on my box (PCEngine APU2).  ???

Same here. Running on a ProtectLI FW6 with an i3 CPU.
Report --> Health --> CPU Temp is showing information, but the "Thermal Sensors" widget on the dashboard is empty.
I have the Thermal Sensor hardware set to coretemp, and it seems to be working per the shell command:

Code Select Expand

root@OPNsense:~ # sysctl -a | grep -E "dev.*temperature|hw.*temperature"
hw.acpi.thermal.tz1.temperature: 29.9C
hw.acpi.thermal.tz0.temperature: 27.9C
dev.cpu.3.temperature: 52.0C
dev.cpu.2.temperature: 52.0C
dev.cpu.1.temperature: 51.0C
dev.cpu.0.temperature: 51.0C


EDIT: It's ridiculous to have to do a BIOS reset and then reconfigure BIOS settings again when the system is clearly reading the temps (see right above). There is something broken in the OPNsense GUI. There has to be a better solution.

Word of note. 20.7 has moved to FreeBSD 12.1, there may be something there that is affecting some devices. I'm running Qotom's and have had no issues.

[lore.phoenix]

@marjohn56
20.7 has moved to HardenBSD 12.1 which is FreeBSD with more security in mind.

I would be surprised that the problem is related on the OS since I was able to read the  temperature via CLI at the moment the Thermal Sensor widget didn't display anything.

I would like to know how the Thermal Sensor widget read the temperature.
Does it read the temperature directly from the system or does it read it's data from the stored database that is used for Report --> Health --> CPU Temp.

Kind regards,

I'm seeing a lot of lines like the first then the two at the end..

Odd seems to be picking up web stuff.

try

# /sbin/sysctl -a | grep temperature:

instead of

# /sbin/sysctl -a | grep temperature

*** EDIT***

What's even more odd is sysctl outputting anything that has web stuff in it.

[nigelw]

try

# /sbin/sysctl -a | grep temperature:

# /sbin/sysctl -a | grep temperature:
dev.cpu.3.temperature: 53.2C

[marjohn56]

Yes, so the grep is seeing the 'temperature' in the junk the sysctl appears to ouput. Can you do this, only if you are having problems with CPU temp:

# /sbin/sysctl -a  > /tmp/sysctrl_output.txt and then post the resultant text file here. It'll be interesting to see what's going on. Also give make model of hardware and amount of ram etc.
