Event Management
Event management is a technology for making sense of a large number of events and pinpointing a few that are really important. This section describes how events received from diverse sources and generated within the system can be managed by Iotellect operators and administrators.
Event management is a complex task involving multiple stages:
Event filtering. At this stage, events that don't match specific criteria (source, severity, domain-specific rules) are being filtered out from processing chains and business views.
Event aggregation. Aggregation, also called event deduplication or reduction, allows the system to minimize the overall number of processed events by joining instances that have matching deduplication IDs.
Event masking. Masking means ignoring events that come from sources that depend on system elements that are deemed failed.
Event correlation. The correlation engine finds simple relations between similar events, usually one of them marking the outset of a certain process or state and the other marking its termination.
Root cause analysis. This is the most complex stage of the event management process. It involves analyzing the relations between events and their environment, followed by finding the cause of each event.
