A Probe Framework for Monitoring Embedded Real-Time Systems

This paper introduces a general framework directed for system instrumentation. The introduced framework provides support for a system instrumentation approach that enables designing information capture, monitoring and analysis features into a software-intensive system. We describe the general concept, architecture and implementation of the framework and two case studies in its application. As a prototyping platform, we dealt with collecting information from Linux systems by probes created with the building blocks and interfaces provided by the framework. Overall, we demonstrate the feasibility of a more uniform instrumentation approach through this concept and its application in two case studies.
