Abstract
Method and system are provided for event relationship analysis in fault management. The method includes: providing a history of a plurality of event instances relating to multiple events identified by event identifiers, where an event instance has one or more event occurrences referencing an event identifier, the history including the event occurrences and resolution event information; analyzing the event occurrences relating to each event identifier to identify a first occurrence(s) of an event instance; analyzing the resolution event information relating to each event identifier to identify any event resolution time for an event instance; comparing two event identifiers to obtain a relationship score between the two event identifiers, wherein the comparing is based on a combination of first occurrences of event instances relating to the two event identifiers and resolution times of the event instances; and creating a group of events that are related based on the relationship scores.
