Abstract: The invention is directed to a computer implemented method and a system that implements an application performance profiler with hardware performance event information. The profiler provides dynamic tracing of application programs, and offers fine-grained hardware performance event profiling at function levels. To control the perturbation on target applications, the profiler also includes a control mechanism to constraint the function profiling overhead within a budget configured by users.
