With event framework,we should use little helper function to wrap each event type,at least that's what I have seen.Windows event tracing(ETW) comes to mind,one of the complex api written[1].I always thought that every application should make use of ETW infrastrucutre. Compared to perf_events or may be lttng in linux(I am not sure how difficult to integrate to perf_events).Currently there are good and easy framework for ETW in .net [2]. But once you integrate your app,your app suddenly gains performance tuning,debugging capability easily. I think this should hold true for any event framework!!
