Instrumentation techniques are widely used for implementing dynamic program analysis tools like profilers or debuggers. While there are many toolkits and frameworks to support the development of such low-level instrumentations, there is little support for the refinement or composition of instrumentations.
A common practice is thus to copy and paste from existing instrumentation code. This, of course, violates well-established software engineering principles, results in code duplication, and hinders maintenance.
In this position paper we identify two challenges regarding the refinement and composition of instrumentations and illustrate them with a running example.
