Intelligent Platform Management Interface, a standard for hardware monitor chip reading
This is created by Phil Edelbrock, one of our main project contributors (Now defunct, but still viewable). An updated version is now included in the lm_sensors package.
After Step fan and temperature monitor
After Step fan, temperature, and voltage monitor. An enhancement of asfatm.
A tool to manage and monitor Linux clusters.
Stijn Jonker's program to make nice graphs of the lm_sensors output. Recommended. Requires mysql package.
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++.
Brendon Humphrey's Gnome display program for lm_sensors. Nice. Recommended.
GTK app. In Italian.
Brendon Humphrey's KDE display program for lm_sensors.
Displays kernel information on an external LCD.
Daniel Schudel's Gnome display program for lm_sensors. Requires GTK--.
A comprehensive system monitoring package. Nice desktop app. Recommended.
A perl script to generate a web page of sensor readings.
A configurable Gnome Panel Applet.
Nice client/server application with a html-embedded Java applet.
wmlm78 and wmsensors are graphical extensions of lm_sensors, which can be docked in Window Manager. By Adrian Baugh.
By J. D.
A very comprehensive package for Windows. Supports many many devices. Also has a great database of motherboards.
This is the original module lm_sensors is based upon
Written by Erik Hendriks. This Nasa site may have a newer version. There is also SCMS Cluster Management for Beowulf clusters available, which supports the LM78 through the above kernel module.
CPU-heating program to stress-test marginally-cooled systems and test lm_sensors. Recommended.
The RRD tool is 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.
A great introduction to SMBus 2.0 and the differences from Version 1.x.
A new standard for system management messages using the SMBus and passing this information to remote management devices. From the Distributed Management Task Force.
