A communication performance analyzing program, a communication performance analyzing apparatus and a communication performance analyzing method make it possible to highly reliably grasp the communication performance of a computer system by automatically analyzing the communication performance. The communication performance analyzing program that causes a computer to analyze a data tendency of communication performance of a plurality of execution periods of a computer system formed by connecting a plurality of computers by a network, the program comprises a communication time acquisition step Sthat acquires communication time data among the computers of the computer system and a statistical analysis step Sthat analyzes the tendency of communication performance data of each execution period of the computer system, using the communication time among the computers, by statistically analyzing the communication time data acquired by the communication time acquisition step.

Communication performance analyzing program, communication performance analyzing apparatus and communication performance analyzing method

The system provides a technique for detecting changes in behavior of a computer system. An address data storing unit obtains an address being accessed by a CPU at prescribed sampling intervals, stores address data comprising the address and its acquisition time in an address record table in time series. Then an executed process detector detects the name of the process that was executed when the address data was obtained, and sets the process name for the address data in the address record table. When an analysis request specifying an analysis time period is made, an analyzer counts up each of the process names included in the address data being stored in the address record table for each specified analysis time period, and analyzes the breakdown of executed processes for each analysis time period. Then a display unit displays the analysis result of the analyzer.
