Temperature Widget
-
Where is the temperature supposed to show up? Can't find it in the system status widget. Or does it show only on certain systems and not on others?
-
It shows up between MBUF Usage and CPU Usage for me. But it always reads 26.8C (which is what tz0 reads, tz1 has the actual CPU temp) for me.
-
Not every system supports temperature mesuaring.
You can try to execute sysctl hw.acpi.thermal as shown by
http://doc.pfsense.org/index.php/What_Hardware_Monitoring_Is_SupportedIf you get an error message, then FreeBSD is not able to fetch the values via acpi and the widget is not shown.

Thanks for that link! I'm a total BSD newbie and didn't know I could get all the values like that. Here's the output on my system if it helps any. Again, the 26.8 is meaningless, and the 33 is the real CPU temp:

Hi, i was curious about the reason why cpu0 temperature mesuaring method wont run on some systems.
I came across
http://os4.org/wiki/freebsd_-_power-management.html
where this matter is discussed in more Detail.Im pretty sure that we really should first try to query acpi.thermal before querying cpu0 and will adapt the code accordingly.
Further on, i think about doing a 'sysctl hw.acpi.thermal | grep 'tz.*temperature' before and just display any value there.
this would also remove the need for the tunable.[2.1-DEVELOPMENT][admin@pfsense.localdomain]/root(4): grep 'tz.*temperature' acpi_thermal hw.acpi.thermal.tz0.temperature: 26.8C hw.acpi.thermal.tz1.temperature: 33.0C -
That sounds like it'd be a perfect solution, if I understand correctly, it would just show any temperatures that exist - bogus or not, correct?

dev.cpu0.temperature is created by coretemp(4).
My box has a Core CPU but the ACPI is broken so I have no thermal zones.Steve

According to intel docs, the Atom D510 has an on-die thermal sensor that can be read.
Looks like BSD or some BIOS issue prevents that from happening, because thesysctl hw.acpi.thermal
returns zilch. :(
Hence, of course, no reported temperature. No wonder I can't see it ;) -

Hi,
afaik acpi was invented after those processor specific extensions were developed.
by now its available on most platforms and supports more sensors.
pfSense currently relies on dev.cpu.temperature and uses ACPI.tz0 as a fallback.
but only one sensorvalue of them is shown and this might be wrong.For this reason i expanded the code in my tree to ask acpi for all the temp sensors.
This will give us more options in the GUI, including to select coretemp when we want.
Ill post a patch when its ready, so everyone can test it.

If motherboard manufacturers bothered to code their ACPI tables correctly there wouldn't be a problem! >:(

…repost...
Hehe, im running on virtualized hardware, so i need to ask my bank to buy a new system which supports the processor specific module ;))
Anyway, both will be supported bythe widget -
Steve, are you referring to the FireBox X500?
Recently my FB X500 fan/blower died and I had to open my X500, put a cpu fan in place of the blower and leave the cover off while I wait for new replacements I ordered off of eBay (from HK of course…) and was wondering if there was a way of enabling such widget for a Celeron 1200Mhz

Nope I was talking about the XTM5.
You can use the output of mbmon to drive the dashboard widget. We had a long thread up on this for 2.0.X, I'm sure a lot of it would be relevent here.

ah, informative - ill read that in a minute.
decided to just post what i got till now:
The code defaults to dev.cpu0 [as is] but is able to handle multiple acpi temperatures too if that module is used instead.function get_temp() { // queries thermal sensors via sysctl. // returns array of sensors and their corresponding values $arr_parsed =""; $arr_temp = array(); $filter_acpi = "tz[0-1].temperature"; // escaping for possible inclusion in config.xml $oid_cpu = escapeshellcmd("dev.cpu0.temperature"); $oid_acpi = escapeshellcmd("hw.acpi.thermal"); // First, query for a processor specific sensor on the die exec("/sbin/sysctl '". $oid_cpu ."' | grep -E 'cpu.*temperature'" , $arr_cpu); // exec ("cat /root/temp_cpu | grep -E 'cpu.0.temperature'" , $arr_cpu); if (arr_cpu != "") { $arr_temp = array_merge($arr_temp,$arr_cpu); } // Alternative: query all acpi thermal zones. exec ("sysctl ". $oid_temp ." | grep -E '". $filter_acpi ."'" , $arr_acpi); // exec ("cat /root/temp_acpi | grep -E '".$filter_acpi."'" , $arr_acpi); if (arr_acpi != "") { $arr_temp = array_merge($arr_temp,$arr_acpi); } foreach (($arr_temp) as $value) { preg_match("/tz[0-9]|cpu/i", $value, $sens_id); // get sensor id preg_match("/[0-9]{1,2}.[0-9]/", $value, $sens_val); // get temperature value $arr_parsed[] = array ($sens_id, $sens_val); } return($arr_parsed); }is nearly finished now but well see. Anyway, its main purpose is to train me some pfSense gui customisation skills, so no problem for me.
Heres what its look like by now:
-
So where do we get the coretemp.ko that's compatible with pfSense 2.1 short of building a BSD 8.3 kernel?
Is this going to end up in the regular distribution at some point or will this remain in the everyone interested hacks it in on their own territory? -
Oh, its written Source independent (see discussion above) to let the users choose what they want to use.
Edit:
Im currently banned from the highspeed World and have to use gprs till eoM. (:grm:)
ill sync wt current git and do the commit as soon as my highpriced provider is able to…till then here are the other changed functions:
function updateTemp(obj_json) { /* modify the red / grey bar gifs according to the temperature ratio is one pixel per degree. */ jQuery.map(obj_json,function(value,index){ tempmeter = "#tempmeter" + value tempwidtha = "#tempwidtha" + value tempwidthb = "#tempwidthb" + value console.log(tempmeter); jQuery(tempwidthb).css('width',(100 - value[1]) + 'px'); if(jQuery(tempmeter)) jQuery(tempmeter).html(value[1] + '\u00B0' + 'C'); if(jQuery(tempwidtha)) jQuery(tempwidtha).css('width',value[1] + 'px'); if(jQuery(tempwidthb)) jQuery(tempwidthb).css('width',(100 - value[1]) + 'px'); });and in system_information.widget.php
Temperature  -
I don't have 2.1 running on anything right now so I can't check but is it not included in the image? If not it just needs copying from a FreeBSD 8.3 install.

Any chance of an option for Deg F ? Large numbers of people just never grokked the metric system sadly. :-\
