Hardware sensors with ipmitool
This check makes use of the output of a working ipmitool on
a Linux system. If the kernel properly supports IPMI and ipmitool
is installed, then the agent will output the current state of
power supplies, cooling devices, temperatures and other devices
avaiable via IPMI. This check makes
sure that all those devices are working properly.
Fortunately, IPMI provides not only the current sensor values but also
their state, so no levels need to be configured for this checks.
This check provides a summarized mode, where all sensors appear as one
summary check per host and a detailed mode with one check per sensor.
Please note: on some systems IPMI reports sensors in a non-ok state wheras
actually no problem exists. As of version 1.1.11i1 these sensors can be
ignored with the configuration variable ipmi_ignored_sensors.
"Summary" for summary mode, the name of the IPMI item
in detailed mode.
In summary mode, one check is created if at least one
sensor is found by the agent. In detailed mode one
item is created for each sensor found.
Note: Some obscure hardware lists sensors in the state
nr which do not produce usable output. If you set
impi_ignore_nr to True then these sensors will
