Abstract: An illustrative embodiment of a computer-implemented process for identification of a root method instruments code to form instrumented code, responsive to a determination thread sampling exists samples execution of the instrumented code in an enhanced runtime to create thread sample data, responsive to a determination a thread sample threshold is exceeded, samples the execution of the instrumented code to create stack sample data, responsive to a determination the stack sample threshold is exceeded, samples the execution of the instrumented code to create method stack sample data, determines whether a root method is identified and responsive to a determination the root method is identified, reports the identified root method for a respective thread.
