The present invention offers a network management technique that can realize effective acquisition of various data transmitted from terminals, while reducing the network congestion. In a network management system including a plurality of terminals that can transmit data, a plurality of destination devices that perform respective predetermined processes based on the data, a relay device arranged between them, and a management device communicable with the terminals, the destination devices, and the relay device, the management device receives a request regarding required data from the destination devices; and, in response to the request, instructs to integrate data items that are to be relayed to individual destination devices. Upon receipt of the instruction, the relay device identifies and integrates data items that are to be relayed to the individual destination devices from among data items transmitted from the terminals, and transmits the integrated data to corresponding ones of the destination devices, based on the instruction.
