Sometimes when rule conditions are met, you may want them to trigger a fault and be alerted immediately. Other times, you may want to only generate a fault when a condition has been met for a period of time. Rule-level aggregates provide the ability to go back through time series after a rule has been evaluated. For instance, this rule must have been in a faulted state for more than 3 hours before a fault is generated.
