Appl. No.:

11/684567

Inventors:

Ludmila Cherkasova - Fort Collins CO, US
Qi Zhang - Fort Collins CO, US
Guy Mathews - Fort Collins CO, US
Wayne Greene - Fort Collins CO, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G06F 15/16
G06F 15/173
G06F 9/46

US Classification:

709226, 709205, 718104

Abstract:

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).

Abstract:

A method comprises receiving a representative workload of a computing system, where the representative workload comprises at least one composite transaction. 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 transactions. For instance, a given transaction for serving a client's request for information (e. g. , a web page) may include embedded therein a plurality of requests/responses for objects (e. g. , images, etc. ) that form the information (e. g. , that form the requested web page). The method further comprises determining, based at least in part on a statistical regression-based analysis, a resource cost for the at least one composite transaction, where the resource cost reflects an amount of utilization of at least one resource of the computing system, such as CPU utilization, in serving the at least one composite transaction.

International Classification:

G06F 9/46

US Classification:

705 7, 718105

Abstract:

A method comprises receiving, by a workload profiler, a representative workload of a computing system under analysis. The workload profiler determines a workload profile of the computing system that reflects a transaction mix that varies over times. A capacity analyzer receives the workload profile, and determines a maximum capacity of the computing system under analysis for serving the workload profile while satisfying a defined quality of service (QoS) target.
