Multiple phase distributed reduction

摘要

A method and system for metric information processing is disclosed in one embodiment. Metric information is gathered with a plurality of points of presence (POPs) geographically distributed across the Internet. The metric information is processed in a hub-and-spoke fashion with a metric reduction occurring in the POPs and another metric reduction in a kernel application server according to predetermined schemes. The two-stage metric reduction generates a result set including a data structure. The result set can be processed according to a query to generate a report. The data structure and reports have metric information that is recent and updated regularly without use of a database.
