摘要： A system is provided in which a server which provides a service to a client terminal, a disk array device upon which data used by the server is stored, and a monitor terminal which detects a bottleneck on the disk array device, are connected via a network. The disk array device or the server calculates performance information including the number of IO requests issued by the server, the times required for processing the IO requests, and a resource utilization ratio for each resource included in the disk array device. The monitor terminal establishes a reference point based upon an average response time obtained by dividing the processing time included in the performance information by the number of the IO requests. And the system is characterized in that a resource is identified as a bottleneck, based upon the resource utilization ratio in a predetermined interval before the reference point.
