1 | Introduction |
| 2 | ------------ | |
| 3 | ||
| 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. |
