Claim:
1. A monitoring apparatus, comprising a memory storing executable instructions; and a processor connected to the memory and configured to execute the instructions, execution of the instructions causes the processor to: capture a network transmission signal from a monitoring location in a monitoring target network; specify each of a plurality of sessions based on session specifying information contained in the network transmission signal; analyze, for specified each of the plurality of sessions, the network transmission signal and measure a quality index; transfer the quality index of each of the plurality of sessions, which is measured every predetermined period of time, as a quality measurement result to an aggregation apparatus until a predetermined threshold value of a processing capability is reached; and stop, when the predetermined threshold value of the processing capability is exceeded, measuring the quality index of one of the plurality of sessions in a high-load state, and in a next cycle to ensure that measurement is performed comprehensively, perform the measurement on one of the plurality of sessions in the high-load state that stopped the measurement and that a transition of a measurement state has been set from a measurement-in-progress state to a not-measured state.
