Abstract:
A system for providing software performance counters includes an operating system that receives a first request of a first application to monitor performance of a second application, the first request identifying a type of event to monitor during the execution of the second application. The operating system determines that the event is a software event, monitors the performance of the second application with respect to the type of the software event, and updates a counter associated with the type of the software event based on the monitoring. Further, the operating system receives a second request of the first application for performance data associated with the type of the software event counter, and provides the value of the counter to the first application.
