  • Publication number: 20150378805
    Abstract: A plurality of multi-purpose diagnostic procedures are associated with a plurality of rules and defined using component types. The rules indicate an association between one or more condition events and a conclusion event. A management system specifies cause candidates based target rules associated with condition events related to the occurrence events, and specifies a multi-purpose diagnostic procedure in association with a target rule that is a basis of a selected cause candidate. The management system creates an expanded diagnostic procedure that is a diagnostic procedure to be performed on one or more management target components for specifying a more specific cause of the selected cause candidate or updating the certainty of the selected cause candidate based on the specified multi-purpose diagnostic procedure and configuration management information that is information about the configuration of a plurality of the management target components.
