Method and system for determining parameter distribution, variance, outliers and trends in computer systems

摘要

A system and method for generating statistical reports showing distribution, variance, outliers and trends for parameters across a set of computer systems is provided. The reports are generated based on audited data for each system that pertains to the parameters. A distribution report assesses the uniformity of the parameters of a population of systems and provides frequency distributions and statistics describing the data values from the analyzed systems. A variance report assesses the conformity of one or more target systems against a reference data set comprised of a set of baseline systems. The report compares each target system individually against the reference data set to measure the consistency of the target's parameters. A trend report shows trends in the uniformity and conformity measures of the parameters by comparing the statistical analysis results of sets of systems at two or more points in time or the different systems at the same time.
