Centralized network monitoring device for monitoring devices via intermediate monitoring devices by means of polling and including display means displaying screens corresponding to heirarchic levels of the monitored devices in a network

摘要

The fault occurrence statuses of each device being monitored and the intermediate monitoring device under which the devices at which faults have occurred are stored in a table, and when the desired screen is selected and displayed based on a map information file, the number of collected faults of each of the devices displayed on the selected screen is displayed in accordance with the above-noted fault occurrence status table. In addition, the invention has a verification status table into which is stored the information as to whether or not detailed fault information for the devices being monitored has been verified, with correspondence established with respect to the upstream intermediate monitoring devices, and displays whether or not faults of each of the devices at each of the heirarchical levels of the network have or have not been verified, in accordance with this verification status table. In addition, the existence of a fault state device which is not shown on the display screen is indicated within that display screen, and further the size of the display screen can be changed to bring that fault state device onto the display screen.
