ABSTRACT:
Methods, systems and apparatus, including computer program products, for profiling an application. An application for execution is obtained. The application comprises a plurality of machine-independent first instructions. Regions of the first instructions that implement one or more programming language methods, functions, or flow control structures are identified. The first instructions are translated into corresponding machine-dependent second instructions for a target machine. The second instructions are instrumented to include sampling instructions for the identified regions. The sampling instructions are configured to cause generation of a state sample when an identified region is executed. Each state sample includes a time stamp and an identification of a currently executing method or function. The second instructions are executed in order to execute the application. During the execution of the application, each generated state sample is collected.
