[Effect of this embodiment]
As described above, in this embodiment, in each managed computer device 20, the manager function unit 22 sends an update request for updating its own life / death information registered in the MIB of the management computer device 10 to the management computer device. 10 is periodically transmitted to the management computer device 10. The management computer device 10 stores an alive state for each managed computer device 20 in the MIB 12, and the agent function unit 11 responds to an update request from the managed computer device 20, In the MIB, the life / death information of the managed computer apparatus 20 is updated, and when the life / death of each managed computer apparatus 20 is monitored, the life / death information of each managed computer apparatus 20 is acquired from the MIB.

  As a result, it is possible to manage the life / death information of each managed computer apparatus 20 by the management computer apparatus 10 without providing an MIB in each managed computer apparatus 20. Therefore, the configuration of each managed computer device 20 can be simplified, and information for life and death monitoring can be centrally managed only by the management computer device 10, and the life and death of each managed computer device 20 can be managed in a small scale system. It becomes possible to monitor.

  Further, in the present embodiment, the manager function unit 22 of the managed computer device 20 requests to update the alive information of the managed computer device 20 to a normal state by an update request, and the agent function unit 11 performs the update request. In response, after updating the life and death information of the managed computer device 20 in the MIB 12 to a normal state and acquiring the life and death information of each managed computer device from the MIB 12 in response to the acquisition request from the monitoring manager function unit 14, The life and death information of each managed computer device 20 may be initialized to an abnormal state.

  As a result, when an update request from the managed computer device 20 is not notified to the management computer device 10, the life / death information in the MIB 12 remains in an abnormal state, and thus an abnormality occurs in the managed computer device 20. Thus, when the update request cannot be notified periodically, it can be automatically determined that the alive state of the managed computer device 20 is abnormal.

  The life / death information stored in the MIB 12 is not limited to “normal” / “abnormal”. For example, when the update request transmission date and time is used as the life and death information, when monitoring the life and death of each managed computer device 20, the time difference between the confirmation date and time of the MIB 12 and the transmission date and time registered in the MIB 12 is checked. Based on the presence or absence of update delay, it is possible to determine whether the managed computer device 20 is active or not, ie, “normal” / “abnormal”.
