  In step S60, the operation confirmation device 17 specifies a service provided by the monitoring target device in which a failure is detected by the process in step S28 or step S30 of the operation confirmation process. In addition, the operation confirmation device 17 executes a plurality of operation confirmation commands corresponding to the specified service by the process of step S32 of the operation confirmation process. Then, the operation confirmation device 17 derives the influence degree of the failure based on the combination of the execution results of the plurality of operation confirmation commands that have been executed by the process of step S34 of the operation confirmation process.

  In step S62, the operation confirmation apparatus 17 monitors the date and time when the failure was detected, the information indicating the service, the date and time when the influence degree was derived, and the derived degree of influence by the process of step S36 of the operation confirmation process. 18 is output. The monitoring terminal 18 receives information on the date and time when the failure output from the operation confirmation device 17 was detected, information indicating the identified service, date and time when the degree of influence was derived, and degree of influence. And as above-mentioned, the monitoring terminal 18 displays the service status display screen shown in FIG. 8 on a display apparatus as an example using each received information.

  The person in charge of the operation visually confirms the service status display screen, and investigates the cause of the failure and performs recovery work according to the date and time of occurrence and the degree of influence displayed on the service status display screen. Then, when the recovery is completed, the person in charge of the operation inputs “Done” as the response status of the line corresponding to the service for which the recovery has been completed on the service status display screen.

  As described above, according to the present embodiment, based on the influence range information 52, the service provided by the monitoring target device in which the failure is detected is specified, and whether or not the specified service is available is confirmed. The operation confirmation process is executed. That is, when a failure of the monitoring target device is detected, it is possible to confirm whether or not the service provided by the monitoring target device in which the failure is detected is operating normally. Therefore, when a failure occurs in at least one of a plurality of devices to be monitored that provide a plurality of services, it is possible to identify the affected range of the failure that has occurred.

In this case, the management apparatus 16 holds information in which the physical device 12 and the service provided by the physical device 12 are associated with each physical device 12. Then, the operation confirmation device 17 refers to the command information 54 and executes an operation confirmation process for confirming whether or not the specified service is available, as in the above embodiment.

  Moreover, although the said embodiment demonstrated the case where the operation confirmation process for confirming whether a service can be used is performed when the failure of a monitoring object apparatus is detected, it is not limited to this. For example, the operation check process may be periodically executed for each service provided by the monitoring target device. In this case, when the execution result of the operation confirmation process becomes abnormal, a mode of detecting that a failure has occurred is exemplified.

  In the above embodiment, when the combination of the execution results of the plurality of operation confirmation commands by the execution unit 44 does not exist in the influence information 56, information indicating “determination impossible” is derived as the influence degree of the failure. Also good. In this case, the form in which the person in charge of operation investigates and determines the state of the service is exemplified.
