Description

  The present invention relates to a monitoring system, a monitoring method, a monitoring target device, a control method, and a control program for the monitoring device to monitor the monitoring target device.

  In a monitoring system in which a monitoring device monitors a monitoring target device, SNMP (Simple Network Management Protocol) that is a monitoring protocol is generally used.

  Since SNMP is a higher-level protocol than UDP (User Datagram Protocol), which is a non-connection type, even if data loss occurs between the monitoring device and the monitoring target device, it cannot be detected. . Therefore, in order to compensate for a state mismatch that occurs between the monitoring device and the monitoring target device, the monitoring device needs to periodically perform connection confirmation and state synchronization of the monitoring target device.

  However, as the scale of the monitoring system increases, the number of monitoring target devices monitored by the monitoring device increases, and the synchronization interval shown in FIG. 5 increases. As a result, the time allotted to the connection confirmation and state synchronization of each of the monitoring target devices # 1 'to #N' (N is an arbitrary integer) is inevitably reduced, and the monitoring device 100 'and the monitoring target device # 1' The time during which a state mismatch with .about. # N 'has occurred becomes long.

  In the monitoring system in which the monitoring device 100 ′ and the monitoring target devices # 1 ′ to # 3 ′ are connected as shown in FIGS. 6 and 7, the monitoring device 100 ′ and the monitoring target device # 2 ′ are connected. And the data between the monitoring device 100 ′ and the monitoring target device # 3 ′ always pass through the monitoring target device # 1 ′, so that the monitoring device 100 and the monitoring target device # 1 ′ The bandwidth between them is shared by the monitoring target devices # 1 ′ to # 3 ′.

  In such a case, if the amount of data between the monitoring device 100 ′ and each of the monitoring target devices # 1 ′ to # 3 ′ is not limited, the monitoring device 100 ′ and the monitoring target device # 1 ′ sharing the bandwidth Data overflow occurs between the two and data loss is likely to occur.

  For this reason, it is necessary to develop a system that efficiently checks the connection.

  In addition, as a technical document filed prior to the present invention, a technique is disclosed that makes it unnecessary to change the main function of the element management system even when the management information provided to the network management system and the access means need to be changed / added. (For example, refer to Patent Document 1).

  In the above-mentioned patent document 1, when an element management receiving unit 11 in the element management system 10 receives a management request from the network management system 20, the management information processing unit displays information on the element management executing unit 13 that should execute the request. 12 and issues a management instruction to the element management execution unit 13. In response to the management request, the element management execution unit 13 manages the corresponding communication device 30 and acquires the management operation result according to the management request. The management information processing unit 12 returns management information corresponding to the management operation result acquired by the element management execution unit 13 to the element management reception unit 11, and the element management reception unit 11 returns the management information to the network management system 20. I have to.

  In addition, there is a document that discloses a technique for improving communication efficiency when a communication apparatus is configured to transmit an operation request to a plurality of communication apparatuses and receive an operation response to the operation request ( For example, see Patent Document 2).

In Patent Document 2, the mediation device 101 that mediates communication between the management device 102 and the plurality of image forming devices 100 collectively receives operation requests addressed to the plurality of image forming devices 100 from the management device 102, The received operation requests are divided for each operation request, and transmitted to the image forming apparatus 100 serving as a destination according to the destination information included in each operation request. Further, the mediating apparatus 101 receives an operation response to the operation request from the image forming apparatus 100, and collectively transmits the received operation responses to the management apparatus 102.
JP 2004-310237 A JP 2004-140818 A

  However, in Patent Document 1, the element management system 10 manages the corresponding communication device 30 according to the management request received from the network management system 20, and acquires the management operation result. Therefore, in Patent Document 1, the element management system 10 does not autonomously manage the communication device 30 existing under the element management system 10.

  Patent Document 2 is an invention based on the premise that an intermediary device 101 is installed between the management device 102 and a plurality of image forming devices 100, and the plurality of image forming devices 100 autonomously collect information. Not what you want. Further, since the mediation apparatus 101 divides the operation request received from the management apparatus 102 for each operation request and transmits the operation request to the image forming apparatus 100, the above-described Patent Document 2 may increase the load on the network. There is.

  Therefore, in the above Patent Documents 1 and 2, the monitoring target device autonomously collects device information of a device adjacent to the monitoring target device itself, and describes what is necessary to efficiently check the connection. Neither has been suggested.

  The present invention has been made in view of the above circumstances, and provides a monitoring system, a monitoring method, a monitoring target device, a control method, and a control program capable of efficiently performing connection confirmation, which are the problems described above.
