“…It is also possible to continue the modeling with additional, lower levels [335]. For example, an application may generate a sequence of requests from different servers, and each such request may be transmitted as a sequence of packets.…”

“…Web activity may be analyzed in terms of a three-layer model similar to the one proposed earlier: the aggregate traffic, the sequences of sessions from individual clients, and the requests within each session [524]. But it is also possible to dissect the data in more detail, leading to some variant of the following multilevel model [36,335,445,535,575]:…”

“…A useful generative model can be constructed based on common activity patterns when using different applications. For example, web browsing can be characterized at the following five levels [36,335,445,535,575]:…”

Reliable performance evaluations require the use of representative workloads. This is no easy task since modern computer systems and their workloads are complex, with many interrelated attributes and complicated structures. Experts often use sophisticated mathematics to analyze and describe workload models, making these models difficult for practitioners to grasp. This book aims to close this gap by emphasizing the intuition and the reasoning behind the definitions and derivations related to the workload models. It provides numerous examples from real production systems, with hundreds of graphs. Using this book, readers will be able to analyze collected workload data and clean it if necessary, derive statistical models that include skewed marginal distributions and correlations, and consider the need for generative models and feedback from the system. The descriptive statistics techniques covered are also useful for other domains.
