A method and system for monitoring performance of a program is provided. A trace record containing a call stack associated with the program is periodically generated. An occurrence of a selected event or a timer interrupt is detected, and in response, an execution context sample is obtained that contains a process identifier, a thread identifier, a program counter, and a stack pointer. A trace record containing the execution context sample data is generated. During post-processing, the execution context samples are compared with a call stack to identify the routine associated with the execution sample data.
