摘要：A system and method for extracting and forecasting computing resource datasuch as workload consumption of mainframe computing resources using an

autoregressive model. The system and method forecast mainframe central processingunit (CPU) consumption with ninety-five percent accuracy using historical performancedata. The system and method also provide an upper ninety-five percent confidence leveland a lower ninety-five percent confidence level. The system and method retrieveperformance records from a computer platform in one second intervals, statisticallycollapses the one second performance data into fifteen minute performance data,statistically collapses the fifteen minute performance data into one week performancedata, and generates a time series equivalent to collecting performance data at one weekintervals. The system and method ensure that the resulting time series is statisticallystationary, and applies an autoregressive construct to the time series to generateforecast of future CPU utilization, as well as to generate reports and graphs comparingactual vs. forecast CPU utilization. Because the system and method rely on electronically

generated empirical historical computer performance data as an input, they provide aturnkey solution to CPU consumption forecasting that can be implemented easily by anysystem network manager.
