WORKLOAD CHARACTERIZATION METHODOLOGY然後construct operational plan to an analysis model,a system model and a level component model。At the system level,we will use the finite population,various service rate model and the component level,we will use the multiple closed explained - class model,as in the Project Description document。The classes will be divided by various file size。Since we plan on perform our study from the server standpoint,we are in the following interested measuring parameters of the system。The arrival rate(request per second)throughput System in HTTP operations per second or in bits per second depending on the type of workload we have。Latency at the server(Response in transaction per second time)Error per secondThe size of the file retrievedComponent - wise measurement:e。g utilization of the CPU and utilization of the disk。然後predict want to the system performan
