ANALYZING METHOD AND DEVICE

摘要

This invention is an analysis method for carrying out an analysis for responses of a computer system including a plurality of servers, and data concerning a CPU utilization ratio of each of the plurality of servers is obtained from the computer system, and the obtained data is stored into a CPU utilization ratio storage. Then, processing history data generated in the computer system is obtained, data of a request frequency by users of the computer system is generated, and generated data is stored into a request frequency data storage. Then, an average delay time in each server is estimated by using the CPU utilization ratio of each server, which is stored in the CPU utilization ratio storage, and the request frequency stored in the request frequency data storage, and the estimated average delay time is stored into a server delay time storage. By carrying out such a processing, the analysis can be carried out without changing the computer system to be analyzed and any additional cost.
