How to: Get CPU temp

[ptt]

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?

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

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

2. Show all cores temp on the dash

1.  Change line 240 in /usr/local/www/widgets/widgets/system_information.widget.php
from

" />

to

" />

2.  Working on that, but this code:

function has_temp() {
	$numcores = "";
	exec("/sbin/sysctl -A | grep temperature | wc -l", $dfout);
	$numcores = trim($dfout[0]);
	if($numcores == "0") {
		return false;
		} else {
		return true;
		}
}

Will check to see if you have temperatures reporting and trigger it to show the temps.  Having it show all of the cores separately will take more work - I'm no coder but I will give it a shot. :)

@breese:

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>

What is the output of sysctl -a | grep temperature

@RedRep Nice work!

@RedRep: u da man !!

This code needs to be incorporated in the future 2.0 snapshots. Who can make it happen?

If there is a function defined to do the following..

1. auto check if mobo supports temp monitor
2. If yes.. execute the coretemp.ko functions, make it to auto load on boot and display the temp in (degree) C for all cores on the dash
3. If not.. hide the Temperature field from the dash.

GREAT POST!

Followed the steps showed in the post.
However I ran into a small issue.
I am on 2.0-RC3  (i386) built on Fri Aug 5 12:14:15 EDT 2011

I downloaded the i386 coretemp.ko.txt from the post here, removed the txt extension.
Copied the file (coretemp.ko) to /boot/kernel/
Made sure the rights were set to 555
Ran the command kldload coretemp and got this error:

Fatal trap 12: page fault while in kernel mode
Cupid = 0; apci id = 00
Fault virtual address     = 0x3afaf300
Fault code                   = supervisor write, page not present

Does anyone else have this issue?  Someone mind hosting two 8kb kernel extensions?

You can try from here: http://ptt.4mg.com/pfSense/

The problem could be that the kernel modules attached to a post in this thread used the .txt extension.
For some reason this causes a problem when they are downloaded corrupting the file.
If you attach binaries with the .png extension this won't happen.

Hi ptt - thanks - but when I try to download fro the link then this:
Forbidden
Host:
You do not have permission to access this page or file
The extension 7z is currently not supported by FreeServers.
If you think there is an error or you wish to have the extension 7z added to the mime definitions, please take the time to notify customer support.
Thank you for using FreeServers.

Thanks Steve, where from can I then get the file?
Cheers Steen

Here is the coretemp.ko file from FreeBSD 8.1 release (386).
Remove the .png extension. The file should be 8054 bytes.

Greatly sorry, changed to zip, now is OK  ( http://ptt.4mg.com/pfSense/ )

You have:

coretemp32.zip–> inside amdtemp.ko & coretemp.ko  ( FreeBSD-8.1-RELEASE-i386 )

coretemp64.zip--> inside amdtemp.ko & coretemp.ko ( FreeBSD-8.1-RELEASE-amd64 )

Hello ptt!
Many thanks!
As per other post it now works for me!

OK, as attached shows dashboard now shows my CPU temp.  ;D  ;)
Thanks to everyone here!

Hi Guys,
I'm still trying to make the coretemp module working but it seems I'm doing something wrong because it still doesn't work  :'(.
I extracted the coretemp.ko from the FreeBSD 8.1 distribution iso and put it to /boot/kernel through a SCP connection authenticated as root.
run the kldload command and tried the command sysctl -a | grep temperature but it returns nothing.

I had no error when typing "kldload coretemp" so it should works !!!

My pfsense box is a Watchguard Firebox X700 hardware which runs on Intel Celeron 1200MHz.
This CPU should be supported by coretemp no ?

Please Help me.

Thanks in advance for your support.
