    Patent number: 6002872
    Abstract: A method for monitoring performance of a program. A periodically occurring event is detected and a stack associated with the program is identified in response to a detection of the periodically occurring event, which may be a timer interrupt. The stack is examined to identify each routine (and specific invocation point, or offset) that is currently executing in association with the program. Each routine (and offset) is represented as a node in a tree structure.
