Minimally Intrusive Real-time Software Instrumentation Technologies

The R&D proposed herein will extend an existing Navy Surface Warfare Center (NSWC) reference architecture that characterizes distributed real-time software systems for Resource Management (RM) and will implement the resulting enhanced capabilities as a set of working tools based upon an existing FishEye Software (FES) Data Distribution Service (DDS) toolkit design. The resulting tools will provide minimally-intrusive instruments that can be injected and adjoined to a distributed real-time software system. Information collected and reasoned by these instruments will provide a basis for Real-Time Publish-Subscribe (RTPS) of combined application data and system events to form a cohesive runtime consolidated-view for remote listeners (data subscribers) that supports RM monitoring and management functions. Additionally, the proposed adjoining tools will enable off-line analysis of collected data and events as well as playback capabilities of “interesting” RM episodes so that Complex Event Processing (CEP) techniques can be applied in order to devise improvements on RM plans for subsequent system operations. This will be an initial step toward adaptive RM for distributed real-time systems.
