- Other protocol information
- IPMI documentation
IPMI (intelligent platform management interface), a standard for hardware
monitor chip reading.
- Installation guides
- Motherboard configuration files
Poject is rather incomplete, help is wanted to develop it further (or start a new one altogether)!
As far we know only one motherboard manufacturer provides sensors.conf files:
Personal collections:
- Hardware monitoring applications using the lm_sensors package
- LM Sensors
First see the
prog
directory in the lm_sensors package for sample applications. In particular,
see Tellerstats, a web-based
hardware monitor created by Phil Edelbrock, one of our main project contributors.
- Freshmeat
A search for "lm_sensors"
brings up a good starter list.
- GNOME Sensors Applet
An applet for the GNOME panel to monitor lm_sensors outputs.
- ASFATM (Afterstep fan and temperature monitor)
A wharf/dock app that is capable of displaying system/CPU temperatures and up to
three fan rotation speeds depending on the hardware being used. The development has
stopped, but you still can download the sources from
Planet Mirror
or LIP6.
- ASFTAVM
(Afterstep fan, temperature and voltage monitor)
An enhancement of ASFATM.
- CheapI2C
A real-time linux I2C bus protocol capture tool using the parallel port.
- Dogsled
A tool to manage and monitor Linux clusters.
- GKrellM
GKrellM is a single process stack of system monitors
which supports applying themes to match its appearance to your
window manager, Gtk, or any other theme. Very popular.
- KSim
KSim is a GKrellM equivalent for KDE. Supports GKrellM skins.
- GPDial Applet
A Gnome applet that displays a specific number from a file on the Gnome panel.
By configuring it for a specific sensor file in /proc, you get a
sensor reading. Requires fam and fam++.
- GSensor
GTK+ application.
- LCD4Linux
Displays kernel information on an external LCD.
- phpSysInfo
Generates a web page with system information, optionally including sensors output.
Recommended.
- ProcMeter 3
A comprehensive system monitoring package. Nice desktop application.
Recommended.
- Sens2web
A Perl script to generate a web page of sensor readings.
- Sensor Sweep Applet
A configurable Gnome panel applet.
- Sensors Server
Nice client/server application with a html-embedded Java applet.
- Sentinelle
A daemon which warns you when your sensor readings reach critical values.
- WMSensors
A Windowmaker dockapp. By Adrian Baugh, maintained by the Debian team.
- WMSens Dockapp
A Windowmaker dockapp that works only with the Winbond 83697HF chipset.
By Jonathan D. Meadows.
- WMgtemp
A Windowmaker dockapp that displays the CPU and system temperatures.
By Roger Dunce.
- WMtemp
Another Windowmaker dockapp that displays the CPU and system temperatures.
By Peter Gnodde. Inspired from WMgtemp.
- Varyfan
A C program to vary the fan speeds for the CPU and case fans according to
the temperature of the CPU and motherboard. By Ian Nicholls, more or less
abandoned.
- xsensors
A X11 version of sensors. Requires GTK+ 2.0. Nice, although many chips are not
supported yet.
- Floyd Davidson has nice monitoring
data graphics generated using
modified tellerstats
scripts
- E-Sensors
An Enlightenment frontend (epplet) to lm_sensors, by Øystein Haare.
- Other hardware monitoring implementations (not using LM Sensors)
- Motherboard Monitor
A very comprehensive package for Windows, unfortunately discontinued.
Supports many many devices. Also has a great
database of motherboards. We wish to thank the author, Alex van Kaam, for the
great cooperation we had.
- Alexander Larsson's
LM78 module
The original module LM Sensors is based upon.
- Beowulf project LM78 module
By Erik Hendriks. Old, probably unmaintained.
- smartmontools
The smartmontools package contains two utility programs
(smartctl and smartd) to control and monitor storage systems
using the Self-Monitoring, Analysis and Reporting Technology
System (SMART) built into most modern ATA and SCSI hard
disks.
- hddtemp
Get the hard drive temperatures
using the Self-Monitoring, Analysis and Reporting Technology
System (SMART) built into most modern ATA and SCSI hard
disks. Much simpler than smartmontools.
- TXWD
Another LM78/LM75 module, by Chris Benndorf.
- Beta SMBus access
through the BIOS interface
Old, obviously abandoned.
- Other useful tools
- CPUBurn
CPU-heating program to stress-test marginally-cooled systems and test
LM Sensors. Highly recommended.
- RRDTool (Round Robin
Database)
A database for readings taken over time, such as sensor data.
The LM Sensors package contains scripts to create and update an RRD database
and graphically display the data on webpages.
