Appendix J: Additional PX3TS Information
Assumption:
Upper Warning threshold is enabled.
Upper Warning = 25 (degrees Celsius)
Assertion Timeout = 5 samples (that is, 5 seconds)
838
In the threshold settings, the Assertion Timeout field postpones the "assertion"
action. It determines how long a sensor must remain in the "worse" new state
before the PX3TS triggers the "assertion" action. If that sensor changes its state
again within the specified wait time, the PX3TS 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. Raritan's 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 PX3TS 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
When a temperature sensor's reading exceeds 25 degrees Celsius, moving from
the "normal" range to the "above upper warning" range, the PX3TS 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 PX3TS performs the "assertion" action to
announce the "above upper warning" state.
•
If the temperature drops below 25 degrees Celsius within 5 seconds, the
PX3TS does NOT perform the "assertion" action.
