Abstract
A user definable set of event rollup relationships are maintained as a configuration element. Transitive closure of event rollup relationships is checked at the time of specification to detect cycles and prevent runtime errors. When an event to be processed is detected, the event is compared to defined rollup relationships and queued events to determined if the detected event may be rolled up into at least one queued event or vice versa. If the detected event may be rolled up into a queued event, the detected event is not queued. When any of the queued event may be rolled up into the detected event, the queued events are deleted if processing has not already begun.
