Method, Computer Program, And Information Processing Apparatus For Analyzing Performance Of Computer System

Abstract

In an information processing apparatus, a calculation unit retrieves data that indicates processing periods of processes executed in each time window constituting an analysis period. The calculation unit then calculates a total processing time for each time window by adding up processing times spent for execution of processes. The calculation unit also calculates a total progress quantity for each time window by adding up progress quantities of the processes. A determination unit determines, based on the total processing time and total progress quantity of each time window, a threshold of the total processing times at which the ratio of an increase of the total progress quantity to an increase of the total processing time is equal to or smaller than a predetermined value. A detection unit detects time windows whose total processing times are equal to or longer than the threshold.
