"To De-assert" and Deassertion Hysteresis
After the PXE asserts a state for a sensor, it may de-assert the same
state later on.
To de-assert a state:
To de-assert a state is to announce the end of the previously asserted,
bad state. Below are good state changes that cause the PXE to
de-assert.
1. above upper critical --> above upper warning
2. above upper warning --> normal
3. below lower warning --> normal
4. below lower critical --> below lower warning
Deassertion Hysteresis:
In the threshold settings dialog, the Deassertion Hysteresis field
determines a new level to turn on the "de-assert" action.
This function is similar to a thermostat, which instructs the air conditioner
to turn on the cooling system when the temperature exceeds a
pre-determined level. "Deassertion Hysteresis" instructs the PXE to
de-assert a state for a sensor only when that sensor's reading hits the
"deassertion" level.
