Abstract
A method and apparatus for analyzing the performance of an information system which provides useful assessments of performance that apply to an aggregate of user nodes in the information system. The method and apparatus may be embodied in a performance analyzer which bases an assessment of the performance of the information system on a set of measurements of a performance parameter for each of the user nodes. The measurements in raw form apply to individual ones of the user nodes. The performance analyzer determines a set of filtered measurements by removing at least one type of variability in the measurements. The performance analyzer then determines a representative performance indication in response to the filtered measurements such that the representative performance indication applies to an aggregate of the user nodes. Information system operators are provided with indications of confidence in the applicability of filtered measurements to the aggregate of user nodes and are provided with alarms that are weighted by the indications of confidence.
