0001 Userspace tools

0004 Introduction
0005 ------------
0006
0007 Most mainboards have sensor chips to monitor system health (like temperatures,
0008 voltages, fans speed). They are often connected through an I2C bus, but some
0009 are also connected directly through the ISA bus.
0010
0011 The kernel drivers make the data from the sensor chips available in the /sys
0012 virtual filesystem. Userspace tools are then used to display the measured
0013 values or configure the chips in a more friendly manner.
0014
0015 Lm-sensors
0016 ----------
0017
0018 Core set of utilities that will allow you to obtain health information,
0019 setup monitoring limits etc. You can get them on their homepage
0020 http://www.lm-sensors.org/ or as a package from your Linux distribution.
0021
0022 If from website:
0023 Get lm-sensors from project web site. Please note, you need only userspace
0024 part, so compile with "make user" and install with "make user_install".
0025
0026 General hints to get things working:
0027
0028 0) get lm-sensors userspace utils
0029 1) compile all drivers in I2C and Hardware Monitoring sections as modules
0030 in your kernel
0031 2) run sensors-detect script, it will tell you what modules you need to load.
0032 3) load them and run "sensors" command, you should see some results.
0033 4) fix sensors.conf, labels, limits, fan divisors
0034 5) if any more problems consult FAQ, or documentation
0035
0036 Other utilities
0037 ---------------
0038
0039 If you want some graphical indicators of system health look for applications
0040 like: gkrellm, ksensors, xsensors, wmtemp, wmsensors, wmgtemp, ksysguardd,
0041 hardware-monitor
0042
0043 If you are server administrator you can try snmpd or mrtgutils.
