AOP-Based Monitoring Instrumentation of JBI-Compliant ESB

The popularity of the Enterprise Service Bus (ESB) pattern as a foundation of Service Oriented Architectures (SOA) for enterprise environments is increasing. Java business integration (JSR-208) is an attempt at Java-centric standardization of the ESB pattern. JSR-208 lacks a complete monitoring facility, which nowadays is crucial for management of complex enterprise environments and for establishing Quality of Service (QoS) and Service Level Agreements (SLA). The aim of this paper is to propose JBI-compliant monitoring enrichment without container source modification, which is realized by means of Aspect Oriented Programming (AOP). The instrumentation design is based on analysis of interfaces specified in JBI and is further verified on the ServiceMix and OpenESB open source JBI containers. The result is a monitoring mechanism compatible with any JBI container and compliant with all stated requirements.
