[1-4. Effect]
As described above, according to the terminal monitoring control apparatus according to the present embodiment, when a display system for monitoring and controlling a plurality of terminal apparatuses 101 connected to the LAN 102 is constructed, the terminal apparatus 101 to be monitored. It is not necessary to register special information (such as trap notification) on the database in advance in the database, or use route information that can be extracted from the normal network connection status. Thus, the terminal device 101 to be monitored can be searched. For this reason, it is possible to reduce the communication load generated by transmitting a dedicated command for search, and it is possible to reduce the trouble of registration.

  Note that “trap notification” is a notification for monitoring the information communication system, and when an abnormality occurs in the monitored terminal device, or when it is not in the correct state that was originally set. In addition, the trap notification is automatically transmitted from the terminal device.

  Further, in the present embodiment, the terminal monitoring control apparatus can perform automatic registration when the registration conditions are matched by registering the registration conditions in advance in the user interface. As a result, it is possible to perform automatic registration without confirming registration simply by connecting the terminal device 101 to the same network.
