How to: Get CPU temp

[seh2000]

I just fund the ° symbol in my word processor symbol library then copied it to:

/usr/local/www/javascript/index/ajax.js

function updateTemp(x) {
if($("tempmeter")) {
$("tempmeter").value = x + '°C';
$("tempwidtha").style.width = x + 'px';
$("tempwidthb").style.width = (100 - x) + 'px';

/usr/local/www/widgets/widgets/system_information.widget.php

Core 1 Temperature

/images/misc/bar_left.gif" height="15" width="4" border="0" align="middle" alt="left bar" />/images/misc/bar_blue.gif" height="15" name="tempwidtha" id="tempwidtha" width="" border="0" align="middle" alt="red bar" />/images/misc/bar_gray.gif" height="15" name="tempwidthb" id="tempwidthb" width="" border="0" align="middle" alt="gray bar" />/images/misc/bar_right.gif" height="15" width="5" border="0" align="middle" alt="right bar" />

Used first the ASCI code, but then the symbol, also I seen some places this around " and other ' around - I use ' hope this helps.
The reason for Core1 instead of CPU is I play with having all four cores displayed.

Nope, it's still doing the same thing for me.  I guess I'll have to wait until someone develops a system package.  Not a big deal.  I'm just curious why it's not showing a temperature, even though I can query through a sysctl statement and get 4 temperatures (with HyperThreading, two temperatures really).  Thanks all!  I'll still keep an eye on this thread.

You should really use °, don't hardcode such a symbol directly in html/js

The Intel 386 coretemp file works for the VIA architecture as well.  I followed the instructions on page 1 of this thread and changed /usr/local/www/includes/functions.inc.php to use "hw.acpi.thermal" instead of "dev.cpu.0.temperature".

Works a champ until an update then I need to reinstall the coretemp.ko module and modify functions.inc.php again.

My version of /usr/local/www/includes/functions.inc.php

function has_temp() {

	/* no known temp monitors available at present */

	/* should only reach here if there is no hardware monitor */
	return true;
}

function get_temp() {
	$temp_out = "";
	exec("/sbin/sysctl hw.acpi.thermal | /usr/bin/awk '{ print $2 }' | /usr/bin/cut -d 'C' -f 1", $dfout);
	$temp_out = trim($dfout[0]);

	return $temp_out;
}

Put the .ko files in /boot/modules and not /boot/kernel, then they won't go away after every update and they still will load as expected.

I would think it would be better to have the get_temp function return a value including the ° symbol.
E.g. 45.2°
That way only one file has to be altered.

@jimp:

I agree. I was surprised it worked actually. It probably depends on what your viewing it on.

Using something like:

function get_temp() {
	$temp_out = "";
	exec("/usr/local/bin/mbmon -I -c1 -T3", $dfout);
	$temp_out = (trim($dfout[0]).'°');

	return $temp_out;
}

Would be better except that the above code only correctly returns ° when it it called from the system widget php code. When it's called from the javascript update function it just shows °.  :-\

Needs a semicolon after that, it's "°"

Steve and jimp,
Sorry for been slow, but what you say is I should not really add the ° symbol to the ajax.js file? But could I add the ASCII code there or better not at all? As I mentioned I am not a good programmer :(

Yeah, this still isn't working for me.  I'm just going to wait until a package is released.

It's bad form (invalid html/js/etc) to put in a symbol instead of the html entity. It may work, but it's not guaranteed to do so.

[stephenw10]

Nope.   ???
Same as before, using:

unction get_temp() {
	$temp_out = "";
	exec("/usr/local/bin/mbmon -I -c1 -T3", $dfout);
	$temp_out = (trim($dfout[0]).'°');

	return $temp_out;
}

Results in initially correct ° then 46.5°C
Hmm.

Steve

It may be getting run through htmlentities somewhere in there then. Might be safe to leave the symbol in there if that is the case.

[stephenw10]

Unfortunately using:

function get_temp() {
	$temp_out = "";
	exec("/usr/local/bin/mbmon -I -c1 -T3", $dfout);
	$temp_out = (trim($dfout[0]).'°');

	return $temp_out;
}

Results in the attached image.

Perhaps the character set is being restricted somewhere?

[jimp]

That's a unicode degree symbol, try a standard ascii one, º

OK, got you, yes correct…
Cheers Steen

[stephenw10]

No different. I entered both º and ° and both result in ��.  :-\

Steve

[jimp]

I'd just leave it out.

(Or convert to Kelvin, no symbol there! ;-)

[stephenw10]

Kelvin nice!  :D

I'll stick with the nasty ° addition to ajax.js. I'm clueless about js, how would one enter that as an ascii code instead? Using ° is not working.

Kelvin - LoL can core temp convert the output?
