Description
LM87 health controller chip provides some measurments of temperature and voltage. Information
becomes available not sooner than 2 minutes after boot up. It is not available if LM87 chip is not
detected successfully. All values are 10 second averages, with short peak values ignored as likely
read errors
Property Description
core - CPU core voltage
3.3v - +3.3V power line voltage
5v - +5V power line voltage
12v - +12V power line voltage
lm87-temp - temperature of the LM87 chip
cpu-temp - temperature of the CPU area
board-temp - temperature of the PCI area
state (read-only: enabled | disabled; default: disabled) - the current state of health monitoring
(whether it is enabled or not)
state-after-reboot (enabled | disabled; default: disabled) - the state of the health monitor after the
reboot
Notes
You cannot change state on the fly, just control, whether the health control will be enabled after
reboot
All themperature values are in Celsius degrees
Example

3.3v: 3.3
5v: 5.02
12v: 12.25
lm87-temp: 33
cpu-temp: 33
board-temp: 26
state: enabled
state-after-reboot: enabled
[admin@Wandy] >
