Appendix K: Additional PX3 Information

In the threshold settings, the Assertion Timeout field postpones or even
cancels the "assertion" action. It determines how long a sensor must be
in the "worse" new state before the PX3 triggers the "assertion" action. If
that sensor changes its state again within the specified wait time, the
PX3 does NOT assert the worse state.
To disable the assertion timeout, set it to 0 (zero).
Note: For most sensors, the measurement unit in the "Assertion
Timeout" field is sample. Sensors are measured every second, so the
timing of a sample is equal to a second. BCM2 is an exception to this,
with a sample of 3 seconds.
How "Assertion Timeout" is helpful:
If you have created an event rule that instructs the PX3 to send
notifications for assertion events, setting the "Assertion Timeout" is
helpful for eliminating a number of notifications that you may receive in
case the sensor's readings fluctuate around a certain threshold.
Assertion Timeout Example for Temperature Sensors
Assumption:
Upper Warning threshold is enabled.
Upper Warning = 25 (degrees Celsius)
Assertion Timeout = 5 samples (that is, 5 seconds)
When a temperature sensor's reading exceeds 25 degrees Celsius,
moving from the "normal" range to the "above upper warning" range, the
PX3 does NOT immediately announce this warning state. Instead it waits
for 5 seconds, and then does either of the following:
If the temperature remains above 25 degrees Celsius in the "above
upper warning" range for 5 seconds, the PX3 performs the
"assertion" action to announce the "above upper warning" state.
If the temperature drops below 25 degrees Celsius within 5 seconds,
the PX3 does NOT perform the "assertion" action.
