A management computer for testing a rule for monitoring a system comprising a plurality of devices, wherein a storage unit of said management computer stores event information for managing past failure events and configuration change events in the system, configuration information for managing the current configuration of the system, and a topology snapshot representing a past configuration of the system, and wherein said management computer is provided with: a configuration information reproduction unit which reproduces a past configuration of the system by use of the aforementioned configuration information and information about the configuration change events, and causes the reproduced past configuration to be reflected in the topology snapshot; and a rule testing unit which applies a cause analysis algorithm to the reproduced past configuration, deduces the cause of a failure using a rule to be tested, and outputs a determination as to whether the rule to be tested can be used to detect the failure. |
