  • Systems and methods for multi-event correlation
    Patent number: 11809920
    Abstract: Provided herein are systems and methods for multi-event correlation. Receiving a stream of events, each leaf rule engine may detect a plurality of events from the stream that matches a characteristic for the leaf rule engine. Each leaf rule engine may identify, from the plurality of events and within a time window, a group of events that satisfies a condition for the respective leaf rule engine. A root conditions engine may receive a stream of leaf events corresponding to the group of events identified by each leaf rule engine. The root conditions engine may identify, from the received stream of leaf events and within a root time window, a collection of events that satisfies a condition for the root conditions engine. A trigger may execute an action according to the collection of events identified within the root time window.
