FIG. 11 shows an attribute information list 1101 of a managed object, for example, an individual device (here, a host computer).

An example that can be considered as attribute information of a management target object will be described.
The management information table 501 stored in the management information database 105 is provided with logical relationship information between managed objects as attribute information. For example, in the case of a computer network, this relation information is obtained from information on a processing procedure called generation when a network system is constructed as a logical connection between a host computer and a terminal. In the case of a multiplexing apparatus, the information is collected from the network creation information, and in an exchange or the like, online collection is performed if possible. The management attribute information is stored in the management information database 105 of the network management apparatus 101, and when a display request is made from an input device 120 such as a keyboard of the display device 103, a certain management is performed through a processing method similar to that of the above-described system operation. Displays managed objects that have a logical relationship with the object. FIG. 12 is a display example of devices (terminals) logically connected to the host computer HOST1. Of course, this display example is only one example, and the display style is not limited.

Further, by tracing the relationship information of the managed objects, it is possible to derive a physical connection path between two managed objects in a logical connection relationship. Everything related to communication, such as hardware of communication equipment, transmission / reception ports, communication lines, and OSI layer elements, is defined as the management target. Therefore, a physical connection path between two managed objects can be derived by following the related information of the managed objects according to a certain rule. Regardless of how the network is defined, for example, a simple communication device or a physical connection path of only a line can be obtained by tracing only the layer element of the first layer of OSI. FIG. 13 shows the physical connection paths of only communication devices and lines according to this rule. Of course, this diagram is also only one example, and the display style is not limited.

This is an example of displaying information of a single managed object or a list of managed object groups to which the managed attribute information of the managed objects constituting the management network belongs at an arbitrary display level.

Another example of using managed attribute information of a managed object is
A management operation such as a test is defined as a management target as a management target, and attribute information is stored in a management information database.
105, and also stores information on the relationship between a certain communication device and a management target. Input device 120 such as a keyboard of the display device 103
When a display request is made from the above, through a processing method similar to the above-described system operation description, it is possible to search for related information of a managed object of a certain communication device and display a list of management operations executable in the managed object. it can.
