OVERVIEW OF THE LM-SENSORS PACKAGE
|
|
==================================
|
|
|
|
The lm-sensors package, version 3, provides user-space support for the
|
|
hardware monitoring drivers in Linux 2.6.5 and later. For older kernel
|
|
versions, you have to use lm-sensors version 2.
|
|
|
|
The directories within this package:
|
|
|
|
* doc
|
|
Documentation.
|
|
* etc
|
|
A sample configuration file for libsensors, and a script to convert
|
|
lm-sensors version 2 configuration files to work with version 3.
|
|
* lib
|
|
The user-space sensors support library code (libsensors).
|
|
* prog
|
|
Several supporting programs. The most important ones are:
|
|
- sensors-detect: A stand-alone program for detecting installed
|
|
hardware and recommending specific modules to load.
|
|
- sensors: A console tool to report sensor readings and set new
|
|
sensor limits.
|
|
- sensord: A daemon to watch sensor values and log problems. It
|
|
includes RRD support.
|
|
|
|
|
|
INSTALLING LM-SENSORS
|
|
---------------------
|
|
|
|
See the INSTALL file.
|
|
|
|
|
|
HARDWARE SUPPORT
|
|
----------------
|
|
|
|
To find out what hardware you have, just run 'sensors-detect' as root.
|
|
|
|
Most modern mainboards incorporate some form of hardware monitoring chips.
|
|
These chips read things like chip temperatures, fan rotation speeds and
|
|
voltage levels. There are quite a few different chips which can be used by
|
|
mainboard builders for approximately the same results.
|
|
|
|
Laptops, on the other hand, rarely expose any hardware monitoring
|
|
chip. They often have some BIOS and/or ACPI magic to get the CPU
|
|
temperature value, but that's about it. For such laptops, the lm-sensors
|
|
package is of no use (sensors-detect will not find anything), and you have
|
|
to use acpi instead.
|
|
|
|
This package doesn't contain chip-specific knowledge. It will support all
|
|
the hardware monitoring chips your kernel has drivers for. In other words,
|
|
if you find out that you have unsupported hardware (e.g. sensors-detect
|
|
told you so) then it means that you need a more recent kernel, or you
|
|
even need to wait for a new kernel driver to be written. Updating the
|
|
lm-sensors package itself will not help.
|
|
|
|
|
|
LIBSENSORS
|
|
----------
|
|
|
|
The kernel drivers communicate their information through the /sys
|
|
interface. Because every motherboard is different, the drivers always
|
|
advert the measurements at their pins. This means that the values they
|
|
report are not always immediately relevant to you. They have to be
|
|
labelled properly, and sometimes they must be scaled to correspond to
|
|
real-world values.
|
|
|
|
libsensors is a (shared or static) library of access functions. It
|
|
offers a simple-to-use interface for applications to access the sensor
|
|
chip readings and configure them as you like. It has a configuration
|
|
file where you can put all the motherboard-specific labels and
|
|
conversion rules. That way, all applications do not need to duplicate
|
|
the effort and can simply link with libsensors and work out of the box.
|
|
|
|
|
|
APPLICATIONS
|
|
------------
|
|
|
|
This package contains an example console program that reports all current
|
|
sensors values. This program is called 'sensors'. You can use it as a
|
|
reference implementation for more intricate programs. It also contains a
|
|
daemon watching for sensor values, logging alarms and feeding an RRD
|
|
database with the sensor measurements.
|
|
|
|
This package does not contain a nice graphical monitor. See
|
|
http://www.lm-sensors.org/wiki/UsefulLinks for pointers to such programs.
