Towards the Performance Visualization of Web-Service Based Applications

In this paper we present an approach to building a monitoring environment which underlies performance visualization for distributed applications. Our focus is to make the J-OCM monitoring system and the TAU-Paravis performance visualization system to collaborate. J-OCM, based on the J-OMIS interface, provides services for on-line monitoring of distributed Java applications. The system uses J-OCM to supply monitoring data on the distributed application, whereas TAUParavis provides advanced visualization of performance data. We managed to integrate J-OCM into TAU/Paravis by developing additional software providing access to the monitor and transformation of raw monitor data into performance data which is presented with 3-D charts. At the end we present an extension, which introduces Web Service monitoring into the integrated environment.
