1 | Introduction |

4 | Most mainboards have sensor chips to monitor system health (like temperatures, | |
5 | voltages, fans speed). They are often connected through an I2C bus, but some | |
6 | are also connected directly through the ISA bus. | |
7 | ||
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. | |

13 | ---------- | |

0d0001dd | 15 | Core set of utilities that will allow you to obtain health information, |
828621dd | 16 | setup monitoring limits etc. You can get them on their homepage |
ec1d86c4 | 17 | http://www.lm-sensors.org/ or as a package from your Linux distribution. |

19 | If from website: | |
0d0001dd JD |
20 | Get lm-sensors from project web site. Please note, you need only userspace |
21 | part, so compile with "make user" and install with "make user_install". | |

22 | |
23 | General hints to get things working: | |
24 | ||
25 | 0) get lm-sensors userspace utils | |
0d0001dd JD |
26 | 1) compile all drivers in I2C and Hardware Monitoring sections as modules |
27 | in your kernel | |
828621dd M |
28 | 2) run sensors-detect script, it will tell you what modules you need to load. |
29 | 3) load them and run "sensors" command, you should see some results. | |
30 | 4) fix sensors.conf, labels, limits, fan divisors | |
31 | 5) if any more problems consult FAQ, or documentation | |

36 | If you want some graphical indicators of system health look for applications | |
37 | like: gkrellm, ksensors, xsensors, wmtemp, wmsensors, wmgtemp, ksysguardd, | |
38 | hardware-monitor | |

40 | If you are server administrator you can try snmpd or mrtgutils. |
