Abstract:
1. A network monitoring system for monitoring a network comprising a plurality of devices, the network monitoring system comprising; extraction condition presenting means for presenting an extraction condition indicating a relationship between performance measurement data of at least one device among the plurality of devices and a given status of the at least one device among a plurality of statuses of the at least one device, the relationship indicating that the performance measurement data that are measured under the given status of the at least one device and transmitted from the at least one device under the given status are to be eliminated upon extracting performance measurement data of the plurality of devices from a performance measuring database; and performance measurement data extracting means for eliminating the performance measurement data of the at least one device, that are measured under the given status of the at least one device and transmitted from the at least one device under the given status, based on the extraction condition indicated by said extraction condition presenting means, and extracting the performance measurement data of the plurality of devices from the performance measuring database, wherein the extracted performance measurement data does not include the eliminated performance measurement data of the at least one device measured under the given status, and wherein said network monitoring system provides the extracted performance measurement data of the plurality of devices that is effective for improvement of the network performance to an operator monitoring the network.
