HOWTO: Temperature Monitoring with coretemp in Sysinfo widget
-
For some reason i can't get coretemp to automatically load upon reboot. I can ssh over and run kldload coretemp and i am up and running. I did edit the loader.conf.local and added coretemp_load="yes". The module is in /boot/modules as well.
Am I missing something else to enable pfsense to load this on boot if i have to reboot the firewall?

File permissions perhaps?
Looks like you're doing everything correctly.Steve

What would i be looking for in relation to file permission? is there a way to test (fake boot process) to see if it would give me an error and why it wouldnt load?
-
should i add the line to loader.conf? or would that be bad? Wasnt sure if the .local may not be utilized for some reason? just thinking out loud.

/boot/loader.conf may change on reinstall; /boot/loader.conf.local is guaranteed to remain untouched by a reinstall.
You might see an error report on coretemp during the early boot (before the kernel is started).

Worked just fine on my Jetway MB with pfSense 2.0.2
coretemp.ko was already in /boot/kernel folder
Edited all files manually
-
will this work for 2.1 to?
-
I have it working on most recent version. Just do the edits manually.

I have it working on my Soekris 6501-50 with atom E6xx proc. and i386 pfSense 2.1.
It shows the temp for 2 cores (hyper threading).
I have manually edited both .php files
Works great. -
cool.
thx
-
Thanks again.
did get som errrors at first i missed some stuff. and some rows didnt match.
you had some line more then me. but wasnt any biggie. -
Works perfectly in release 2.0.3, which already has included coretemp modules! Only the PHP files need to be modified.
I suggest to pull these in for everybody, by default in the installation media.
-
The coretemp modules and a dashboard temperature reading is included by default in 2.1. I don't think it is graphed though.

OK thanks, didn't know that, I'm just upgrading to 2.0.3…

If anyone wants to graph these temperatures in Munin, using the munin-node on pfSense based on this, here's a plugin for that:
#!/bin/sh # Plugin to monitor Jetway motherboard CPU temperatures on pfSense controller runtime data.

Munin Plugin updated for 8-core cpu temperature (tested on Supermicro A1SRi-2758F):
