Management system and management program

A technique determines which configuration change(s) caused an application invocation failure of a computer application without the need for a knowledge database. To determine which configuration change is the most likely cause, the cause analysis program checks other computers that have experienced the same configuration changes. The cause analysis program checks and counts the application invocation results before and after each configuration change is done. If the same configuration changes are found in the other computers, the program checks whether each configuration change caused or cured the same problem in that computer. The program counts the similar cases for all of the computers. Subsequently, the program calculates the ratio of those instances involving a change from success to failure and the ratio of those instances involving a change from failure to success out of all instances for each configuration change.

Method and apparatus for cause analysis involving configuration changes

A root cause analysis engine uses event survival times and gradual deletion of events to improve analysis accuracy and reduce the number of required calculations. Certainty factors of relevant rules are recalculated every time notification of an event is received. The calculation results are held in a rule memory in the analysis engine. Each event has a survival time, and when the time has expired, that event is deleted from the rule memory. Events held in the rule memory can be deleted without affecting other events held in the rule memory. The analysis engine can then re-calculate the certainty factor of each rule by only performing the re-calculation with respect to affected rules that are related with the deleted event. The calculation cost can be reduced because analysis engine processes events incrementally or decrementally. Analysis engine can determine the most possible conclusion even if one or more condition elements were not true, because analysis engine can calculate the certainty factor of rule even if one or more events were not notified to analysis engine.

Method and system for performing root cause analysis

The present invention makes it possible to analyze a problem spanning multiple domains. A management apparatus stores an analysis rule. The analysis rule defines a relationship between a causal event, which constitutes a cause of a problem, and multiple relevant events, which denote problems created by the causal event. A first management apparatus acquires a relevant event related to a prescribed node apparatus, which is not under management of the first management apparatus, from a second management apparatus, which manages the prescribed node apparatus. The first management apparatus analyzes a problem by applying the relevant event acquired from the second management apparatus and another relevant event related to a node apparatus under the management of the first management apparatus to the analysis rule.
