Empty coretemp entries in thermal sensors widget

[netnerdy]

I get:

[2.4.5-RELEASE][admin@pfSense]/root: /sbin/sysctl -q dev.cpu | grep temperature | sort
dev.cpu.0.temperature: 49.0C
dev.cpu.1.temperature: 49.0C
dev.cpu.2.temperature: 50.0C
dev.cpu.3.temperature: 50.0C

Try using just: sysctl -aq | grep temperature which is what your device would be checking.

This is what I get when I run that command:

coretemp0: critical temperature detected, suggest system shutdown
coretemp0: critical temperature detected, suggest system shutdown
coretemp0: critical temperature detected, suggest system shutdown

Aha! So it's matching the word 'temperature' in the warnings there.

I would expect that to change after a reboot though, you say it appears identically?

Has it actually overheated? That looks like it must be passively cooled.

You could try changing the grep to match more accurately. So, for example, set that line in thermal_sensors.widget.php to:

		$_gb = exec("/sbin/sysctl -aq | grep temperature:", $dfout);

This looks like an easy fix, even I can do it! Opened a bug to track:

@stephenw10 said in Empty coretemp entries in thermal sensors widget:

Your right !!
I was linking the master (future 2.5.0 ...) code.
The 2.4.5 code is what most of us are using right now.
I was already using the new '2.5.0' code myself for identical reasons.
Just one line to change and you'll be fine.

Thanks everyone for the help.

Yes, it is a passively cooled machine. Not sure why reboot didn't clear the logs. Maybe it reached critical temp during bootup?

[stephenw10]

I would think at least the ordering would be somewhat random if it happened at boot. Probably not something that's cleared at boot then.
It would be interesting to see where in the sysctl output that is shown. It's probably possible to clear it manually if we know what is generating it.

I changed the php file under /usr/local/www/widgets/widgets/thermal_sensors.widget.php and it worked. Thanks!
