The thing is, perf is *already* well beyond the 'passive observer' role: we already generate lots of 'action' in response to events. We generate notification signals, we write events - all of which can (and does) modify program behavior. So what's your point? There's no "passive observer" role really - it's apparently just that you dislike this use of instrumentation while you approve of other uses. Thanks, Ingo
