Abstract
Abstract A method for evaluating the performance of a data processor system includes data collection, analysis, and report generation. The data collection involves the periodic selection of a number of metrics, which are measurable values in the data processing system, and system parameters, which are system values that can be adjusted. The analysis involves the application of certain rules comparing metrics and parameters to corresponding thresholds. The report generation includes the display of recommendations to be taken when certain rules have triggered a certain number of times, and, if desired, the presentation of displays of certain work load characteristics of either the data processor system by itself or of a network of such data processor system.
