1. A computer-implemented method, comprising:

  • a hardware counter counting to a predetermined value;

    in response to the hardware counter reaching the predetermined value, collecting data corresponding to a runtime event;

    determining if the runtime event is of a given event type; and

    in response to determining that the runtime event is of the given event type, incrementing a synthesized counter configured to monitor events of the given event type, wherein the synthesized counter is implemented as a storage location in machine addressable memory.
