Abstract: The present invention realizes root cause analysis processing with a high certainty factor while holding down management cost. In the present invention, besides one or more condition events which could occur in a node apparatus, an additional event different from the condition events is introduced into an analysis rule for a root cause analysis. This analysis rule indicates a relation between the condition events and additional event and a conclusion event recognized as a failure factor according to satisfaction of the condition events and additional event. The additional event is a command for instructing execution of an action for acquiring additional information from the node apparatus according to a satisfaction state of the one or more condition events.

Abstract: A system monitoring apparatus specifies an intentionally shutdown system component or monitoring target, and a different monitoring target that is dependent thereon (a dependent target), and does not display an alert even when an error state is detected for a monitoring target inside the intentionally shutdown system component or the intentionally shutdown monitoring target, and the dependent target of the system component or monitoring target.
