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