Complete instrumentation requirements for performance analysis of Web based technologies

In this paper we present the eDragon environment, a research platform created to perform complete performance analysis of new Web-based technologies. eDragon enables the understanding of how application servers work in both sequential and parallel platforms offering a new insight in the usage of system resources. The environment is composed of a set of instrumentation modules, a performance analysis and visualization tool and a set of experimental methodologies to perform complete performance analysis of Web-based technologies. This paper describes the design and implementation of this research platform and highlights some of its main functionalities. We will also show how a detailed analytical view can be obtained through the application of a bottom-up strategy, starting with a group of system events and advancing to more complex performance metrics using a continuous derivation process.
