1 Userspace tools 2 =============== 3 4 Introduction 5 ------------ 6 7 Most mainboards have sensor chips to monitor system health (like temperatures, 8 voltages, fans speed). They are often connected through an I2C bus, but some 9 are also connected directly through the ISA bus. 10 11 The kernel drivers make the data from the sensor chips available in the /sys 12 virtual filesystem. Userspace tools are then used to display the measured 13 values or configure the chips in a more friendly manner. 14 15 Lm-sensors 16 ---------- 17 18 Core set of utilities that will allow you to obtain health information, 19 setup monitoring limits etc. You can get them on their homepage 20 http://www.lm-sensors.org/ or as a package from your Linux distribution. 21 22 If from website: 23 Get lm-sensors from project web site. Please note, you need only userspace 24 part, so compile with "make user" and install with "make user_install". 25 26 General hints to get things working: 27 28 0) get lm-sensors userspace utils 29 1) compile all drivers in I2C and Hardware Monitoring sections as modules 30 in your kernel 31 2) run sensors-detect script, it will tell you what modules you need to load. 32 3) load them and run "sensors" command, you should see some results. 33 4) fix sensors.conf, labels, limits, fan divisors 34 5) if any more problems consult FAQ, or documentation 35 36 Other utilities 37 --------------- 38 39 If you want some graphical indicators of system health look for applications 40 like: gkrellm, ksensors, xsensors, wmtemp, wmsensors, wmgtemp, ksysguardd, 41 hardware-monitor 42 43 If you are server administrator you can try snmpd or mrtgutils.
