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