trigger owner as the event owner. The event-name argument is a case-sensitive string of 1 to 32
characters.
value integer-value: Specifies a delta falling threshold in the range of –2147483648 to 2147483647.
The value must be smaller than or equal to the delta rising threshold.
Usage guidelines
A falling event is triggered if the delta value (difference between the current sampled value and the
previous sampled value) is smaller than or equal to the delta falling threshold.
If the delta value crosses the delta falling threshold multiple times in succession, a falling event is
triggered only for the first crossing.
