Implementations of the present disclosure provide computer-implemented methods including defining a workload comprising a plurality of service requests, each service request corresponding to a class of a plurality of classes, applying the workload to a computer system that receives and processes service requests, measuring a response time of the computer system for each request of the workload, estimating a mean service demand for each class based on the response times and a base queuing model that represents the computer system, and generating the queuing model based on the mean service demands and characteristics of the workload.

Estimating service resource consumption based on response time

A message handler may receive a plurality of messages associated with a plurality of events, the events having a temporal relationship to one another. A header inspector may extract latency information from the plurality of messages, the latency information characterizing a transmission duration experienced by each message in traveling from the one or more source nodes through the network. A window manager may correct a disruption in the temporal relationship between at least two events of the plurality of events, the disruption including relative differences in the transmission duration experienced by the at least two events, including relating the at least two events to a time window for processing the at least two events. An event processor may process the at least two events relative to the time window.
