Supporting business services through Web service compositions (WSC) as part of service-oriented architectures involves various runtime monitoring requirements. The implementation of these requirements results in additional development activities. Due to the lack of standards for treating such WSC monitoring concerns, a corresponding development approach has to deal with a variety of specific technologies. This paper therefore introduces a platform-independent approach to the instrumentation of WSC and the generation of an effective monitoring infrastructure based on the principles of model-driven software development (MDSD).
