1. A method for monitoring performance of a program, the method comprising the steps of:

  • generating a trace record comprising a call stack associated with the program;

    detecting an occurrence of a selected event or timer interrupt;

    in response to a detection of the selected event or the timer interrupt, obtaining execution context sample data;

    generating a trace record comprising the execution context sample data;

    comparing the execution context sample data to calibration call stack data in order to match full call stack context, wherein calibration call stack data includes context derived from call stack unwinds of a previous execution of said program; and

    identifying a routine associated with the execution context sample data based on a comparison of the execution context sample data to the calibration call stack data.
