Abstract: 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 S2 that acquires communication time data among the computers of the computer system and a statistical analysis step S3 that 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.

Abstract: 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.

Abstract: A system analysis apparatus acquires time series data representing information on a series of processes executed in a computer system in a time-serial manner. A run table shows the ratio of the number of runs of each process to the total number of processes executed in a predetermined unit time in a time-serial manner. A first graph is displayed representing ratios of a series of processes which has been executed in a time-serial manner by collecting the ratio of each process stored in the run table. A moving average of the ratio of each process is calculated by referring to the run table when a parameter change for the first graph is accepted. A second graph is displayed representing the ratios of the series of processes executed by collecting the moving average of each process.

Abstract: A computer-readable recording medium storing a system analysis program capable of detecting changes in behavior occurring in a very short time without fail. 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.

Abstract: A recording medium which is readable by a computer stores a performance analyzing program for searching for a node that is peculiar in performance in a cluster system, as well as unknown problems. The performance analyzing program enables the computer to function as various functional units. A performance data analyzing unit collects performance data of nodes which make up the cluster system from performance data storage unit for storing a plurality of types of performance data of the nodes, and analyzes performance values of the nodes based on the collected performance data. A classifying unit classifies the nodes into a plurality of groups by statistically processing the performance data collected by the performance data analyzing unit according to a predetermined classifying condition.

Abstract: In image data retrieval, image data that becomes the base of search is specified. When the search is to be carried out according to the distance from the image data on an image map, an automatic setting process of retrieval information is carried out. Here, a keyword, icon, chromaticity and the like of that image data are automatically set as retrieval information. The position of that image data on the image map becomes the center of a range when the ambiguity is set. By setting the ambiguity of the image map, keyword, icon, chromaticity, and the like in this state, the range of ambiguity is displayed, and image data within that range is automatically retrieved. As a result, analogous image data can be searched for according to subtle and ambiguous information or information that cannot be quantified.
