Performance analysis tools for enterprise Distributed Real-time and Embedded (DRE) systems require instrumenting heterogeneous sources (such as application- and system-level hardware and software resources). Traditional techniques for software instrumentation of such systems, however, are tightly coupled to system design and metrics of interest. It is therefore hard for system testers to increase their knowledge base and analytical capabilities for enterprise DRE system performance using existing instrumentation techniques when metrics of interest are not known during initial system design. This paper provides two contributions to research on software instrumentation for enterprise DRE systems.
