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

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 or set or the | |
10 | data in a more friendly manner. | |
11 | ||
12 | Lm-sensors | |
13 | ---------- | |
14 | ||
15 | Core set of utilites that will allow you to obtain health information, | |
16 | setup monitoring limits etc. You can get them on their homepage | |
17 | http://www.lm-sensors.nu/ or as a package from your Linux distribution. | |
18 | ||
19 | If from website: | |
20 | Get lmsensors from project web site. Please note, you need only userspace | |
21 | part, so compile with "make user_install" target. | |
22 | ||
23 | General hints to get things working: | |
24 | ||
25 | 0) get lm-sensors userspace utils | |
26 | 1) compile all drivers in I2C section as modules in your kernel | |
27 | 2) run sensors-detect script, it will tell you what modules you need to load. | |
28 | 3) load them and run "sensors" command, you should see some results. | |
29 | 4) fix sensors.conf, labels, limits, fan divisors | |
30 | 5) if any more problems consult FAQ, or documentation | |
31 | ||
32 | Other utilites | |
33 | -------------- | |
34 | ||
35 | If you want some graphical indicators of system health look for applications | |
36 | like: gkrellm, ksensors, xsensors, wmtemp, wmsensors, wmgtemp, ksysguardd, | |
37 | hardware-monitor | |
38 | ||
39 | If you are server administrator you can try snmpd or mrtgutils. |
