With complexity of systems increasing and customer
requirements for QoS growing, new methods and modeling techniques that
explain large-systems' behavior and help predict their future
performance are required to effectively tackle the emerging
performance issues. To accurately answer capacity planning questions
for an existing production system with a real workload mix, we propose a
new capacity planning framework that is based on the following three
components: i) a Workload Profiler that dynamically builds the
workload profile; ii) a Regression-based Solver that is
used for deriving the CPU demand of client transactions on a given
hardware; and iii) an Analytical model that is based on a
network of queues representing the different tiers. To validate our
approach, we conduct a detailed case study using the access logs from
two heterogeneous production servers that represent customized client
accesses to a popular and actively used HP Open View Service Desk
