| 1. An analysis method for analyzing an information processing system having a plurality of information processing apparatuses
providing services to each other by an analyzer, comprising the steps of:
acquiring a plurality of communication packets sent or received between the apparatuses during a specified analysis period
as an analysis subject by the analyzer;
computing a service call count called wherein each of the information processing apparatuses in the plurality of information
processing apparatuses is called by another information processing apparatus in the plurality of information processing apparatuses,
based upon the communication packet acquired by the analyzer during a divided period;
computing a busy time, which is a sum of a time period where the plurality of information processing apparatuses execute a
transaction, which is service processing, by the analyzer per divided period; and
computing an average processing time wherein a sum of square of a difference between the busy time for each divided period
and a number of calls per service during the divided period multiplied by the average processing time of transaction for processing
the service is minimized per service by the analyzer.
