Performance visualization of Web Services using J-OCM and SCIRun/TAU

Abstract. This paper presents a performance visualization tool, developed to provide advanced 3-D performance visualization of distributed applications, based on the integration of the J-OCM monitoring system into the SCIRun/TAU visualization environment. Following the changes in the J-OCM monitoring system, we have done some extensions to SCIRun to support Web Services performance visualization. The paper addresses the common problem of measuring SOAP messages parsing time. It describes the way the tool can be configured and the way it works. The idea is illustrated with use case diagram and sequence diagrams. At the end we present the case study of a ”Hello world ” Web service monitoring session.
