Throttling Examples

Throttling examples explain how the throttling conditions (T1, T2, S1, S2, S3) are combined and evaluated.

note

"Tick" means impulse from the trigger. "T" stands for time-based criteria, "S" stands for statistical criteria. "S3" stands for event log criteria.

S1: Criterion for occurrences (allow every third tick)

This criterion has no state; therefore trigger modifications have no effect on the results.

T2: Allow a single tick in a time interval (allow at most once every five seconds)
