Description: Sensor groups directory for POWER9 powernv servers
|
|
|
|
Each folder in this directory contains a sensor group
|
|
which are classified based on type of the sensor
|
|
like power, temperature, frequency, current, etc. They
|
|
can also indicate the group of sensors belonging to
|
|
different owners like CSM, Profiler, Job-Scheduler

Description: Sysfs file to clear the min-max of all the sensors
|
|
belonging to the group.
|
|
|
|
Writing 1 to this file will clear the minimum and
|
|
maximum values of all the sensors in the group.
|
|
In POWER9, the min-max of a sensor is the historical minimum
|
|
and maximum value of the sensor cached by OCC.
