Monitoring CPU temperature

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I have recently rebuilt my linux box, and the new motherboard/bios can tell
me the current temperature of the CPU, but only if I go into the BIOS setup
program at boot-time. Is there a utility that can monitor this information
for me in real time?

Can you describe how you got it running under SuSE 10.1? The Linux
Journal article seems to describe a generic Linux, while SuSE has
already some components pre installed.

sensors-2.10.0-10 is already installed and /etc/sensors exists already.
Do I have to install the components mentioned in the article anyway?


Invoking "sensors" tells me
Can't access procfs/sysfs file
Unable to find i2c bus information;
For 2.6 kernels, make sure you have mounted sysfs and libsensors
was compiled with sysfs support!
For older kernels, make sure you have done 'modprobe i2c-proc'!

mount | grep sysfs
sysfs on /sys type sysfs (rw)

What else to do?

Hi
You need to detect them first, run sensors-detect.

run "sensors-detect"

Sorry - these are my notes they will need to be customized to your board,
===================================
The interface /proc/bus/i2c/ is provided by loading kernel modules.
Which modules to load can be interactively detected as root by calling
/usr/sbin/sensors-detect.
The default configuration in /etc/sensors.conf should be changed to fit
the actual set up of the mainboard
Also see http://www.lm-sensors.org/
================
the following were determined from running /usr/sbin/sensors-detect.
To make the sensors modules behave correctly, add these lines to
/etc/modules.conf:
#?????????????----cut here----
# I2C module options
alias char-major-89 i2c-dev
#?????????----cut here----
============================
To load the modules that are needed, add this to /etc/init.d/boot.local
##### loading of hw sensors ######
#----cut here----
# I2C adapter drivers
modprobe i2c-isa
# I2C chip drivers
modprobe it87
# sleep 2 # optional
/usr/bin/sensors -s # recommended
#----cut here----
#????????????----cut here----

That's what I did

I missed/overlooked this one

sensors detect also told me to add some modprobe-lines to an /etc/rc
file, but since SuSE uses /etc/init.d/foo files instead I created a file
/etc/init.d/sensors but didn't activate it with chkconfig sensors add,
because I detected that there was already a file /etc/init.d/lm_sensors.

After rebooting my machine, sensors showed me a list of voltages and
temperatures. None of the GUI front ends mentioned in the article are
pre-installed. Are there any SuSE-RPMs for the GUIs?

The voltage list btw seems to be wrong:
-12V: -4.04 V (min = -12.63 V, max = -11.41 V) ALARM
-5V: -13.64 V (min = -5.26 V, max = -4.77 V) ALARM

Frontends - gdesklets, superkaramba and gkrellm (and of course others like
ksensors). Each is a base to which additional functionality can be added
(actually only gkrellm has stuff to begin with). I think they're all inc.
in the dist and additional modules can be downloaded. Gkrellm should have
all you'd want in the base product (Guru has rpm's if needed.) and it
would be my recommendation.

I checked with yast2 sw_single and only the original DVD as installation
source (no packman, no guru) and only found GKrellM. It's quite obvious
to configure.

Thank you,
