Method for analyzing input/output performance of a data processing system

摘要

A method for analyzing input/output performance of a data processing system. The method comprises providing records of input/output operations performed by the data processing system. Each record has statistics related to a respective input/output operation for a respective process. One or more workload classes are specified for accumulating statistics, and the statistics from the input/output records are accumulated by workload class. The accumulated statistics are reported by workload class which supports analysis of the input/output behavior for different workload classes.
