System and method for continuously measuring quality of service in a federated application environment

摘要

A system and method for measuring quality-of-service in a federated application environment is described. One or more administrative domains are provided with each administrative domain being interconnected with at least one other administrative domain to form the federated application environment. One or more interconnected network nodes are situated within each administrative domain with each network node including at least one capsule interface within which a managed method is executed. Instrumentation is associated with each capsule interface of each network node with the instrumentation collecting performance data on the managed method being executed within the capsule interface. A count sensor determines a processing time with the instrumentation within the capsule interface for each managed method. A network sensor determines send and receive bandwidth demand information with the instrumentation within the capsule interface for each managed method. A demand sensor determines physical host resource demands as needed to satisfy invocations of the managed method with the instrumentation within the capsule interface for each managed method. An interval sensor determines response times with the instrumentation within the capsule interface for each managed method. A display displays the throughput metrics, bandwidth demand metrics, service demand metrics and response time metrics.
