An Aspect-Oriented Approach for Dynamic Monitoring of a Service Logic Execution Environment

摘要

Service creation environments play a relevant role in new telecom applications because they enable openness and pro-grammability by offering frameworks for the development of value-added services. The Java application programming interface for integrated networks service logic execution environment (JSLEE) specification defines a Java framework for executing event-based distributed services made up of components called service building blocks. In such a complex architecture, monitoring is an indispensable technique to test the dynamic behavior of a system, debug the code, gather usage statistics, or measure the quality of service. Program instrumentation is needed to insert monitoring codes into the system to be monitored, which is typically a manual and time-consuming task. This paper describes a language-based approach to automate program instrumentation and monitoring management using a dynamic aspect-oriented programming (AOP) framework.
