Monitoring of Distributed Component Interactions

This paper presents a framework for monitoring component interactions. It is part of a larger component framework built on top of the CORBA distributed processing environment that supports development and testing of distributed software applications. The proposed framework considers an OMG IDL specification as a contract for distributed interactions and allows precise monitoring of interaction activities between application components. The developer is not burdened with monitoring issues because all the necessary code instrumentation is done automatically. The tester is given the opportunity to use monitoring facilities for observing interactions between distributed component applications. This paper explains the monitoring framework and reasons about its expressive power, accuracy and applicability. The approach is validated in a platform for design, development and deployment of on-line services. 1. Introduction Distributed applications are becoming one of the major types of sof..
