What is lm_sensors ?
lm_Sensors is an Opensource Hardware health monitor. Monitor system sensors such as CPU and motherboard temperature.
Installation process
- install it through yum
#yum install lm_sensors
or you can install it through RPM ( http://fr2.rpmfind.net//linux/RPM/redhat/7.3/i386/lm_sensors-2.6.1-1.i386.html )
# wget http://fr2.rpmfind.net//linux/RPM/redhat/7.3/i386/lm_sensors-2.6.1-1.i386.html
# rpm -Uvh lm_sensors-2.6.1-1.i386.rpm
2. Detect the sensors on your mainboard, (run as root)
# /usr/sbin/sensors-detect
Accept all the default values.
At the end it will print out something like:
To make the sensors modules behave correctly, add these lines to
/etc/modprobe.conf:#—-cut here—-
# I2C module options
alias char-major-89 i2c-dev
#—-cut here—-
Add the line, as instructed, to the end of /etc/modprobe.conf file.
3. Ignore the other instructions. Now run:
#service lm_sensors start
This will start the lm_sensors service.
Now run:
#sensors -s
There should be no output.
Next run:
#sensors
You should see output like this :
# sensors
