For upper thresholds, this "deassertion" level is a decrease against each
threshold. For lower thresholds, this level is an increase to each
threshold.
For example:
If Deassertion Hysterresis = 2,
Upper Critical = 33, so its "deassertion" level = 33 - 2 = 31.
Upper Warning = 25, so its "deassertion" level = 25 - 2 = 23.
Lower Critical = 10, so its "deassertion" level = 10 + 2 = 12.
Lower Warning = 18, so its "deassertion" level = 18 + 2 = 20.
To use each threshold as the "deassertion" level instead of determining a
new level, set the Deassertion Hysteresis to 0 (zero).
When 'Deassertion Hysteresis' is helpful:
If you have created an event rule that instructs the PXE to send
notifications for deassertion events, setting the "Deassertion Hysteresis"
is helpful for eliminating a number of notifications that you may receive in
case a sensor's reading fluctuates around a certain threshold.
