METHOD AND APPARATUS FOR COLLECTING DATA FOR CHARACTERIZING HTTP SESSION WORKLOADS

摘要

A web server comprising multiple computer systems includes at least one system which maintains a database of redundant session-persistent data on behalf of other systems which process HTTP session workloads for clients. A session analyzer extracts information from this redundancy database to characterize HTTP session workloads. Preferably, session workloads are processed by middleware comprising an application server and one or more applications. The application server maintains session-persistent data as data objects, and automatically updates the database of redundant data which responses are transmitted to a clients. The session analyzer independently extracts data from the redundant database to characterize the session workloads. Optionally, the analyzer includes an intelligent inferencing function which can make tuning recommendations from the extracted data.
