Abstract: A method and system of managing performance of data transfers for a data access system providing data transfers from content servers to remote users in response to user requests, includes calculating performance data summaries at least at a subset of the user sites and transmitting the data for receipt for remote summarization and storage. The data include information indicative of transfer size, throughput, transfer time, source, time and date. The method and system include selecting a quantity of the performance data received, preferably over a time interval, and summarizing and storing the data. Further summarizes can also be calculated. The data may be used to ascertain conditions and manage the performance of the data access system. In the preferred embodiment, the method and system measure performance of Internet HTTP server applications.

Abstract: A method for generating statistical information for performance management reporting is provided. Raw statistical information provided by managed data network equipment is described in a body of vendor data network equipment specific metadata—the collection of which is referred to as vendor statistics metadata. The statistical information needed for performance reporting is described in a body of performance reporting metadata. The method has a sequence of steps. In an initial syntactic translation step, the vendor statistics metadata is used to transform raw statistical information provided by managed data network equipment into a common format removing vendor dependencies while maintaining vendor semantics. In a second semantic extraction step, the statistical information for performance reporting is extracted in accordance to specifications described in a body of statistics semantic mapping metadata from a body of common format statistic information in accordance with prespecified preferences.
