Abstract
A method for analyzing performance of an information processing system having information processing apparatuses providing services to each other. Communication packets sent or received between the apparatuses are acquired. The apparatuses receive calls from other apparatuses for providing services indicated in the packets. A service call count aof the calls received by the apparatuses during period j of m periods for the service i of n services is computed. A busy time bis computed by summing processing times by the apparatuses for performing the services pertaining to the calls received by the apparatuses during period j. An average processing time dis computed by the apparatuses for each service i, as is an error εin dwherein ε=b−Σad, by minimizing an index indicative of ε. The average processing time dis stored in a storage device and/or displayed on a display device.
