Abstract
A system, method and computer program product for sampling computer system performance data are provided. The system includes a sample buffer to store instrumentation data while capturing trace data in a trace array, where the instrumentation data enables measurement of computer system performance. The system further includes a sample interrupt generator to assert a sample interrupt indicating that the instrumentation data is available to read. The sample interrupt is asserted in response to storing the instrumentation data in the sample buffer.
