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 aji of the calls received by the apparatuses during period j of m periods for the service i of n services is computed. A busy time bj is 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 di is computed by the apparatuses for each service i, as is an error εj in di wherein εj=bj−Σiajidi, by minimizing an index indicative of εj. The average processing time di is stored in a storage device and/or displayed on a display device.
