FINE-GRAINED PERFORMANCE MODELING METHOD FOR WEB APPLICATION AND SYSTEM THEREOF

摘要

A fine-grained performance modeling method for a web application and a system thereof are disclosed. The modeling method comprises: 1) setting an updating period for a middleware platform of the web application system; 2) extracting operating data of the middleware platform of the web application system in one updating period; 3) obtaining performance date of the middleware platform of the web application system according to the operating data; 4) generating and displaying a layered queuing network performance model of the web application system according to the current performance data. The modeling system comprises a status updating module, a log loading module and an analyzing module. The modeling system and method construct performance model automatically based on the operating data monitored by the web application platform and a statistical mode without the participation of humans, and carry out updates along with the changes of the system status. The granularity of the constructed model follows the standard web application component model, can be applied in various web application platforms; thereby the usage of the web application system can be truly reflected.
