How to: Get CPU temp

GoldServe

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

Thank you !!

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?

@stephenw10:

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

Edit: Should be °C if you ask me. ;)

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.

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!

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?

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

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. :)

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..

auto check if mobo supports temp monitor
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
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.
