System and method for determining a subset of transactions of a computing system for use in determining resource costs

摘要

A method comprises receiving a representative workload of a computing system, where the representative workload comprises a plurality of composite transactions. In certain embodiments, the representative workload is a historical workload of a computing system. In general, a composite transaction refers to a transaction that comprises a plurality of embedded transactions. The method further comprises determining a subset of the plurality of composite transactions for which a corresponding resource cost is to be determined; and determining, based at least in part on a statistical regression-based analysis, a resource cost for the composite transaction(s) in the determined subset, where the resource cost reflects an amount of utilization of at least one resource of the computing system in serving the composite transaction(s).
