1Introduction
2------------

4Most mainboards have sensor chips to monitor system health (like temperatures,
5voltages, fans speed). They are often connected through an I2C bus, but some
6are also connected directly through the ISA bus.
7
8The kernel drivers make the data from the sensor chips available in the /sys
9virtual filesystem. Userspace tools are then used to display or set or the
10data in a more friendly manner.

12Lm-sensors
13----------
14
15Core set of utilites that will allow you to obtain health information,
16setup monitoring limits etc. You can get them on their homepage
17http://www.lm-sensors.nu/ or as a package from your Linux distribution.
18
19If from website:
20Get lmsensors from project web site. Please note, you need only userspace
21part, so compile with "make user_install" target.
22
23General hints to get things working:
24
250) get lm-sensors userspace utils
261) compile all drivers in I2C section as modules in your kernel
272) run sensors-detect script, it will tell you what modules you need to load.
283) load them and run "sensors" command, you should see some results.
294) fix sensors.conf, labels, limits, fan divisors
305) if any more problems consult FAQ, or documentation

32Other utilites
33--------------
34
35If you want some graphical indicators of system health look for applications
36like: gkrellm, ksensors, xsensors, wmtemp, wmsensors, wmgtemp, ksysguardd,
37hardware-monitor
38
39If you are server administrator you can try snmpd or mrtgutils.
