Tools for monitoring SMART capable disks.

yum install smartmontools
chkconfig smartd on
service smartd start

Show SMART info:

smartctl --all /dev/sda

Install kernel module (the install will take a while, generating the initramfs file):

rpm -Uvh http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpm
yum install kmod-k10temp

Install lm_sensors:

yum install lm_sensors
sensors-detect

Show temperature:

# sensors
k10temp-pci-00c3
Adapter: PCI adapter
temp1:       +54.0°C  (high = +70.0°C, crit = +100.0°C)

bashrc example

if [ -n "$PS1" ]; then
  echo
  sensors |grep temp1 |awk '{print $1 $2}'
fi;
