How to: Get CPU temp

stephenw10 · Aug 4, 2011, 9:16 PM

There's surely some reason that isn't included already?
What happens if coretemp isn't loaded?

let see, i ran kldunload coretemp then looked at the dash… its in the dash but only reads C

I loaded it up and it showed on the dash without refreshing the page :-)

Right, so it needs some code to stop it showing "temperature C" if you don't have the right hardware/driver installed.

Steve

Edit: Should be °C if you ask me. ;)

There is a function in functions.inc.php for that; I will add that functionality tonight after work. I also grabbed the coretemp module for the amd release which I will upload somewhere as well. On an iPad right now though. :(

@Cino:

@RedRep and i thought my box was hot at 52c

It is completely fanless. :)

Eagerly waiting for the amd64 coretemp module !! ;D

Keeping myself ready for the change.. I am getting the below error.

[2.0-RC3][admin@pfsense.localdomain]/boot/kernel(5): pkg_add -r wget
Fetching ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages-8.1-release/Latest/wget.tbz… Done.

wget: Command not found.

Not sure why my wget command isin't working? Is this too 32/64 bit sensitive? I have amd64 installed.

Maybe "fetch" would work.. but not sure what would be the precise syntax for it to download the coretemp.ko file.

Edit:
Nevermind.. I used File Manager to upload the file for testing. Doesn't work..lol. Will wait for the amd64 version.

You have to issue a rehash after you've added a package so Freebsd knows where to find it. Or reboot.

[2.0-RC3][root@pfsense.fire.box]/root(1): rehash

Aah I see. Thanks for the info. Not much of a FreeBSD user so learning every day.

Can't wait to try the amd64 coretemp.

My N270 is 52-55C in a totally passively cooled solution (Lanner netapp).

AMD64 version

Thank you !!

asterix · Aug 5, 2011, 6:11 AM

It's working !!

[2.0-RC3][admin@pfsense.localdomain]/root(1): sysctl -a | grep temperature
dev.cpu.0.temperature: 59.0C
dev.cpu.1.temperature: 54.0C
dev.cpu.2.temperature: 57.0C
dev.cpu.3.temperature: 51.0C

Added to local.conf to auto load at boot.. yeehaa !!!

Now how do I make the temp show up at the main system information for all 4 cores?

agreed…. I did try to add ° but it didn't like it.... Figure we need ANSI code or something for it to display in the widget

Hi RedRep,
I'm very interested in your way to get CPU temperature.
Unfortunately, The link you indicate to download the coretemp.ko package is no more available.
I'm trying to get it from another URL but no success.

Could you put it on pfsense forum or sharing website like megaupload ?

It would be very nice.

thank you very much.

AhnHEL · Aug 5, 2011, 10:27 PM

Uploaded the AMD64 version to here

http://www.megaupload.com/?d=628LSQRC

I don't have the 386 version but I do have a long term unlimited megaupload account so if someone sends it to me I can upload it for others to use as well.

I downloaded the AMD64 8.1 iso from the freebsd FTP servers.
Opened it with WinRAR and browsed to the /boot/kernel/ folder and dragged and dropped "coretemp.ko" into a WinSCP session connected to pfsense.
Edited the file properties to 555. (r-xr-xr-x)
Done!

breese · Aug 5, 2011, 10:36 PM

Any ideas on why I cannot get the main screen to show my tmeps?

Aug 5 17:16:45 kernel: p4tcc1: <cpu frequency="" thermal="" control="">on cpu1
Aug 5 17:16:45 kernel: p4tcc0: <cpu frequency="" thermal="" control="">on cpu0</cpu></cpu>

Just tested on my 2 pfSense Boxes, ATOM D510 & AMD X2 5600+ and works fine ;D

Thanks RedRep, GoldServe, stephenw10 & Tikimotel

If someone needs, here are the coretemp ( i386 ) & amdtemp ( amd64 )

( just remove the txt ext )

coretemp.ko.txt
amdtemp.ko.txt

I would love to see this officially added to pfsense.
However, what about multi core cpus?

adrianhensler · Aug 6, 2011, 12:25 AM

Thanks for a fun thread.

My AMD Geode is 44 C just in case anyone is interested. A jetway board in a matx case.

Superb work guys !!

Now 2 things added to this will make it even more kewl !! :D

Add a degree (°) before the C
Show all cores temp on the dash
