An approach to determine the service demand of various resources of any individual server (present in a cluster of servers), given the overall transaction throughput and utilization values of these resources, in case of a network load balanced scenario is disclosed. The method proposes a quantitative approach to calculate the transaction throughput of each network load balanced server from the overall transaction throughput, obtained from any commercial performance testing tool. The individual transaction throughputs are calculated using monitored values of network related performance counters of each server and the load balancer obtained from performance testing. Service demands of the resource can be computed using the Utilization law of Queuing Theory once the throughput of that server and utilization of that resource is obtained.

Method for determining service demands in a network load balanced scenario

A system adapted for analyzing performance and scalability of at least one computer system is disclosed. The system include a monitoring module configured for capturing at least one metric of an application for analyzing performance and scalability and a performance knowledge repository created and represented by using the at least one metric captured by the monitoring module. The system further includes a diagnosis module adapted for mapping the at least one metric to the performance knowledge repository using a diagnosis module and an analysis module configured for conducting performance and scalability analysis based on the mapping of the at least one metric for detecting at least one undesirable condition.
