instrumentation: The insertion of additional code into the program in order to collect information about program behaviour during program execution.


Frameworks to collect

From http://citeseer.ist.psu.edu/arnold01framework.html

The practice of adding code to collect profiling information can cause substantial execution overhead. This overhead makes instrumentation difficult to perform at runtime, often preventing many known offline feedback-directed optimizations from being used in online systems. This paper presents a general framework for performing instrumentation sampling to reduce the overhead of previously expensive instrumentation. The framework is simple and effective, using code-duplication and counter-based sampling...
