PERFORMANCE ANALYSIS METHOD, PERFORMANCE ANALYSIS PROGRAM AND PERFORMANCE ANALYSIS DEVICE

摘要

PROBLEM TO BE SOLVED: To grasp a call relation among a plurality of processing upon execution of same processing by a plurality of machines distributed in a wide area.SOLUTION: A performance analysis method is provided that allows a computer to execute processing of: calculating a time interval until second processing is firstly called since first processing of the plurality of processing is called on the basis of log information in which each processing of the plurality of processing calls other processing in a system executing plurality of processing to provide services; acquiring identification information on stations where the plurality of machines exist and distribution information indicative of the number of machines for each of the plurality of machines from a load distribution device distributing the second processing to a plurality of machines; and determining that the first processing and the second processing are in a call relation when the number of groups to be classified based on the calculated time interval is equal to the number of stations to be identified based on the identification information, and a ratio of the number of time intervals for each of the groups to be classified is equal to a ratio of the number of machines for each station.SELECTED DRAWING: Figure 12
