#1512 — How to monitor and graph the temperature of my CPU

Hi everyone,

Is there a possibility to regulary grab the temperature of my pc / cpu 
and write it in a file, so that I can later graph it or send it to me 
via E-Mail?

I am using Ubuntu 11.04 x64.

-- 
Thanks in advance,
Anton

Thanks,
I solved it doing the following:
Creating a script named however you like

#!/bin/sh
/usr/bin/sensors | /bin/grep '^temp1:' |  awk '{print($2) }' | cut -c 
2-5 >> /home/anton/temps

adding the following line to crontab (executing it every 5 minutes)

0-59/5 * * * *  root    /home/anton/appz/tempmon/tempmon


And then plotting it manually with

echo 'plot "/home/anton/temps" using 1 with line title "CPU", "" using 2 
with line title "HDD"' | gnuplot -persist -

Probably this will look some different for any other system, but thats a 
beginning, isn't it? ;)

You can avoid "sensors" and go directly to the source:
cat /proc/acpi/thermal_zone/THM0/temperature

Depends on which kernel module is being used.  I have the acpi,acpid,
and acpitool packages installed, but the /proc/acpi/thermal_zone
directory does not exist.

Only by running sensors under strace did I figure out where it is
with the it87 kernel module.  It's /sys/class/hwmon/hwmon0/temp1_input,
which has the temp with an extra three zeros after it.

Thank you!

When I get a free moment I want to fired up rrdtool

Still does not work. In the /proc/acpi - folder, I can only find the 
following:
ac_adapter  battery  button  event  wakeup

Looks like I have to use Sensors ;)

Yes and the best way to do this is with a combination of sensord and
round-robin-database tools as well as installing a web server on your
machine so that you can easily see the graphs created via your web browser
(either locally or remotely).

sensord (which is the daemon related to the lm-sensors package which is
the interface to your CPU temperaturs, fans etc) has an rrd interface
ready to use, activated when the daemon is started via its startup script.

   Package: sensord
   Description: hardware sensor information logging daemon
   Lm-sensors is a hardware health monitoring package for Linux. It allows you
   to access information from temperature, voltage, and fan speed sensors. It
   works with most newer systems.

   Package: rrdtool

   Description: time-series data storage and display system (programs)
   The Round Robin Database Tool (RRDtool) is a system to store and display
   time-series data (e.g. network bandwidth, machine-room temperature,
   server load average). It stores the data in Round Robin Databases (RRDs),
   a very compact way that will not expand over time. RRDtool processes the
   extracted data to enforce a certain data density, allowing for useful
   graphical representation of data values.


And if you want the temperatures from your hard disks as well, then you can
run hdtemplogd, write your own daemon (eg in Perl) and save the data to
another rrd, and display the graphs of temperature of the disks on the
same web page (or even on the same graph of CPU temperature), all depending
on how you setup your cgi bin program to display the rrd data on the web page.

The big advantage of using rrd for this type of monitoring is that the
old data gets overwritten, so you do not have the problem of an ever
increasing database.

I have been developing stuff that gets data values and pops them in  a 
Mysql database, and other scripts which read them out and create graphs.


Got some reasonable generic graphing tools using pngwriter.

too rough to publish a s community code, but a reasonable starting point 
for those that want C code to draw lines..

I am sure it is good enough for what you need to do, but the "Opensource industry
standard" (to quote the web page) that already does all of that is rrdtool

      <http://www.mrtg.ORG/rrdtool/>

the software I mentioned in my post.

For data whose worth expires periodically, a round robin database
is the right thing to chose.

See examples of the graphs (in PNG format) that can be produced with
rrdtool at

      <http://www.mrtg.ORG/rrdtool/gallery/index.en.html>

apt-get install lmsensors

It could prints to text file.

As usual you are about 3 posts behind, even though your are 8 hours
in the future.  ;)

For a complete solution,

apt-get install
                 lmsensors
                 sensord
                 rrdtool
                 apache2   (to serve up web page of the graphs)


The cgi-bin file that is needed is in HTML/RRD sytax and
this extracts the data from the RRD databases created by
sensord (and in this case an hdtemp logging daemon) eg

<UL><LI><H2>&nbsp;Daily Temperature Summary</H2></LI></UL>

<RRD::GRAPH daily-temperature.png
 --alt-autoscale-max
 --imginfo '<IMG SRC=/sensors/%s WIDTH=%lu HEIGHT=%lu>'
 --lazy
 -a PNG
 -h 300 -w 800
 -l 0 -s -1d
 -v 'Temperature (degrees C)'
 -t 'Temperature'
 -x 'HOUR:1:HOUR:3:HOUR:3:0:%b %d %H:00'
 DEF:temperature_cpu=<RRD::GETVAR RRD_FILE_MB>:temp1:AVERAGE
 DEF:temperature_mb=<RRD::GETVAR RRD_FILE_MB>:temp2:AVERAGE
 DEF:temperature_sda=<RRD::GETVAR RRD_FILE_SDA>:temperature:AVERAGE
 DEF:temperature_sdb=<RRD::GETVAR RRD_FILE_SDB>:temperature:AVERAGE
 LINE2:temperature_cpu#fb221e:"CPU"
 LINE2:temperature_mb#8b4567:"Mother Board"
 LINE2:temperature_sda#48945a:"Disk /dev/sda"
 LINE2:temperature_sdb#485a94:"Disk /dev/sdb">

</P>


And at the top of the cgi-bin file if you have

<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
<META HTTP-EQUIV="Pragma"        CONTENT="no-cache">
<META HTTP-EQUIV="Refresh"       CONTENT="720">

then the web page auto updates with the new data plotted
every 12 minutes (720 seconds).

Forgive me, Your Honor! I am still in REST mode. :)

No need to use CGI. Just cat the results into a text file, set its 
permission and ownership properly, serve the file using Apache, and view 
it from a browser.

It's just a script executed periodically by cron. :)

You give the impression of having been in REST mode for
the past 5 years or more!  ;)

You say just cat.  Which process does the catting?

A PNG file is not a text file.

> serve the file using Apache

The file needs to be created from the last data on
demand, which is why you need cgi-bin.

You really have not thought this through ...

Did you even bother to look at the multitude of graphs
(including temperature monitoring) that rrdtool can produced
on the web site link I provided?
