<P>PROBLEM TO BE SOLVED: To provide a method for execution of root cause analysis for a problem occurring in a giant and complicated IT system. <P>SOLUTION: A root cause analysis engine uses event duration and gradual event deletion to increase analysis accuracy and reduces the number of required calculations. Whenever an event notice is received, a matching ratio of a related rule is recalculated. A calculation result is stored in a rule memory within the analysis engine. Each event has validity, and when the duration expires, the event is deleted from the rule memory. The event stored in the rule memory is deletable without affecting other events stored in the rule memory. Then, the analysis engine recalculates the matching raito of each rule by recalculating only the rule affected in relation to the deleted event. <P>COPYRIGHT: (C)2013,JPO&INPIT |
