METHOD, SYSTEM AND COMPUTER PROGRAM PRODUCT FOR EVENT-BASED SAMPLING TO MONITOR COMPUTER SYSTEM PERFORMANCE |
摘要 |
A system, method and computer program product for event-based sampling to monitor computer system performance are provided. The system includes a sample buffer to store a sample of instrumentation data, where the instrumentation data enables measurement of computer system performance. The system also includes a sample segment selector to isolate a segment of the sample of instrumentation data as an event. The system further includes an instrumentation counter counting in response to a combination of the event and a sample pulse, and asserting a sample interrupt indicating that the sample of instrumentation data is ready to logout from the sample buffer. |
