System diagnosis apparatus, system diagnosis method and computer-readable recording medium recording system diagnosis program

摘要

A system diagnosis apparatus comprises a communication processing device which acquires a utility rate of the system resources of a user system and a queue for the system resources, a memory device stores thresholds of the utility rate and the queue. An analysis device is provided which decides that the performance of the system resource has lowered when the utility rate is more than its threshold and the queue is shorter than its threshold, or decides that the number of system resources is insufficient when the utility rate is more than its threshold and the queue is longer than its threshold.
