Abstract: An information processing apparatus executes a process and a second server in an information processing system including a first server, the second server, and a third server. The process includes: collecting, in a first queue, traffic data that is transmitted and received by the second server; acquiring, from the first server, a client request reception time when the first server receives a request from a client and a client response time when the first server responds to the request from the client; and moving, to a second queue, traffic data of a time period from a first server request reception time when the second server receives a request from the first server after the client request reception time to a first server response time when the second server responds to the request from the first server before the client response time.
