[0002]

2. Description of the Related Art Generally, in the field of monitoring devices to be monitored connected to a network, a plurality of lower-level devices to be monitored are individually monitored by a plurality of middle-level monitoring devices, and the monitoring results of each of the middle-level monitoring devices are monitored. Monitoring systems that are individually transferred to a higher-level monitoring device are widely known.

[0003] In the following description, a lower monitoring target device is referred to as a monitoring target node, and a middle monitoring device is referred to as a child monitoring device (C

It is an object to provide a switching program, a method, and a monitoring system.

[0012]

The gist of the present invention is to collectively input address information of a lower monitoring target to be newly registered / deleted to a higher monitoring device, and the higher monitoring device inputs this address information to each middle monitoring device. With this configuration, even if a large number of lower monitoring targets are dynamically changed, monitoring is continued in accordance with the change. The middle-level monitoring device has a function of newly registering / deleting lower-level monitoring targets based on address information allocated from the higher-level monitoring device. Further, the term “new registration” may be read as “added”. In addition, the same address information may be “deleted” from one child monitoring device and then “added” to another child monitoring device, and this set of “deletion / addition” may be called “change”.

A monitoring target switching program for individually switching each of the lower monitoring targets, wherein the computer of the higher monitoring device is provided with identification information of a middle monitoring device corresponding in advance for each range of address information of the lower monitoring target. When the address information of a newly registered lower-level monitoring target is collectively input, the input address is set for each corresponding middle-level monitoring device by referring to the monitoring range setting means. This is a monitoring target switching program for functioning as a registered information batch sending unit that batch sends corresponding address information of the information.

According to a second aspect, in the first aspect, when the address information of the lower monitoring target to be deleted is input collectively, the computer of the upper monitoring device is referred to by referring to the monitoring range setting means. This is a monitoring target switching program for functioning as a deletion information batch transmission unit for batch transmitting the corresponding address information of the input address information for each of the middle-level monitoring devices.

The third invention is used in a monitoring system in which a plurality of lower-level monitoring targets are individually monitored by a plurality of middle-level monitoring devices, and the monitoring results of the respective middle-level monitoring devices are individually transferred to a higher-level monitoring device. A monitoring target switching program for individually switching the respective lower monitoring targets, wherein the computer of each of the middle monitoring devices collectively receives address information of the lower monitoring targets to be registered from the higher monitoring device. A monitoring target switching program for functioning as a monitoring target registration unit for registering a lower monitoring target based on the address information.

In a fourth aspect based on the third aspect, when the computer of each of the middle-level monitoring devices collectively receives, from the higher-level monitoring device, the address information of the lower-level monitoring target to be deleted, This is a monitoring target switching program for functioning as a monitoring target deletion unit for deleting a lower monitoring target based on the monitoring target. Note that the first and third inventions may be combined into one set, and the second and fourth inventions may be combined into one set. Further, the first to fourth inventions may be simultaneously realized.

(Operation) Accordingly, the present invention takes the above-described measures to collectively input address information of a lower monitoring target to be newly registered / deleted to a higher monitoring apparatus, and the higher monitoring apparatus inputs this address information. Information is distributed to each middle-level monitoring device, and each middle-level monitoring device
