Sensors & Controls

lm_sensors

yum install lm_sensors

Configuration

/usr/sbin/sensors-detect
/etc/sensors.conf
/etc/sysconfig/lm_sensors
/etc/modprobe.conf

Problems & Upgrade

hddtemp

Installation

yum install hddtemp

Configuration /etc/sysconfig/hddtemp

HDDTEMP_OPTIONS="-l 127.0.0.1 --syslog=900 /dev/sda /dev/sdb /dev/sdc"

This logs the drive temperaturs for 3 drives every 15 mins ( i.e. 900 seconds )

cpuspeed

http://www.carlthompson.net/Software/CPUSpeed

Requires a laptop cpu that is capable of scaling.

A CPU capable of scaling its frequency and / or voltage. Many modern mobile CPUs found in laptop computers can do this, including the Mobile AMD Athlon 64, Mobile AMD Athlon XP-M, the Intel Pentium 4M, the Intel Centrino, Mobile AMD Sempron, Mobile AMD Turion 64 and the Transmeta Crusoe. (Note that some laptop computers may actually have desktop CPUs which are not capable of scaling. These CPUs cannot be used and should be avoided when purchasing a new laptop computer.)

rpm

showing package architecture

from http://fedoraproject.org/wiki/Docs/Beats#RPM_multiarch_support_on_64-bit_platforms_.28x86_64.2C_ppc64.29

RPM multiarch support on 64-bit platforms (x86_64, ppc64)

RPM supports parallel installation of multiple architectures of the same package. 
A default package listing such as rpm -qa might appear to include duplicate packages, 
since the architecture is not displayed. Instead, use the repoquery command, 
part of the yum-utils package, which displays architecture by default. 
To install yum-utils, run the following command:

 su -c 'yum install yum-utils'

To list all packages with their architecture using rpm, run the following command:

 rpm -qa --queryformat "%{name}-%{version}-%{release}.%{arch}\n"

You can add this to /etc/rpm/macros (for a system wide setting) 
or ~/.rpmmacros (for a per-user setting). 
It changes the default query to list the architecture:

 %_query_all_fmt         %%{name}-%%{version}-%%{release}.%%{arch}
