Abstract
A system for obtaining performance data for different performance events includes a first application monitoring performance of a second application executing on a computing system. The first application identifies the type of event to be measured with respect to the second application, issues a first system call identifying the type of event, receives an identifier corresponding to the event type, and causes the second application to begin execution. After the execution of the second application is completed, the first application issues a second system call including the identifier corresponding to the event type, and receives a value of a hardware counter corresponding to the event type from an operating system.
