Tools for a Model-driven Instrumentation for Monitoring

The performance of parallel and distributed systems depends significantly on how the programs ' execution is dynamically organized. Therefore, performance evaluation and efficient programming of parallel and distributed systems need the analysis of the internal behavior of such systems. For this purpose event-driven monitoring is an appropriate technique. Eventdriven monitoring reduces the dynamic internal behavior of the system to some important events, which are recorded in event traces. The instrumentation of the object program, i.e. the definition of events, depends on the respective intention of the analysis. In most cases the instrumentation will be done intuitively based on professional experience. In this paper a concept for a model-driven execution of event-driven monitoring is presented. It leads to tools for systematic and automatic instrumentation. 1. Introduction The use of more and more complex computer systems, for example multiprocessor or multicomputer systems, needs ..
