Diverting condition storage unit 15 stores diverting conditions describing conditions for hardware configurations and software configurations. Monitoring data storage unit 13 stores monitoring data on the hardware configurations and the software configurations on monitored devices. Monitoring setting information storage unit stores monitoring setting information on the monitored devices. By referencing monitoring data and diverting conditions, first setting-diverting unit judges if monitoring setting information set in a monitored device may be diverted as monitoring setting information on another monitored device and outputs the result to a management terminal. The system administrator diverts the monitoring setting information among multiple monitored devices based on judgment result.
