BOTTLENECK DETECTION DEVICE, METHOD AND RECORDING MEDIUM STORING PROGRAM

摘要

In a method which analyzes system behavior using performance indices related to time, a program portion that has become a bottleneck is discovered; however, discovery is not made back to the cause of the same. This bottleneck detection method, when varying a load to measure behavior of a system, performs measurement regarding a plurality of performance indices. Then by analyzing the results of the same by way of analysis unit, program portions that are bottlenecks are identified, and causes of the program portions being bottlenecks are identified.

1. A bottleneck detection device comprising:
storage unit which stores performance indicator values each obtained by measuring an individual performance indicator with respect to each part of processing executed by an information processing apparatus; generation unit which generates a feature vector based on the stored performance indicator values for each part of the processing; and determination unit which, based on the generated feature vectors, determines a part of the processing that forms a bottleneck in performance of the information processing apparatus, and a performance indicator found as a cause that results in the bottleneck.
