A storage apparatus in a computer system, which includes a computer usage-status information reporting unit. When a computer makes an I/O request to the storage apparatus, the computer and a device for which I/O has been requested by the computer are identified, and the amount of data that has been transferred when I/O operations are performed, a cache hit ratio, and a processing time are measured. Then, the above information obtained and the above values measured are stored in the computer usage-status information in the storage apparatus. By using the computer usage-status information reporting unit, the stored computer usage-status information is referenced from the outside of the storage apparatus.
