While we're on the topic of tracing, does anyone know an _easy to use_ (!) tool that would roughly mirror the functionality of Apple Instruments for user-space tracking? I know there's lttng-ust and TraceCompass, but using either (and especially TraceCompas) is worse than pulling teeth. To display a simple trace in a "piano roll" / Gantt chart view with TraceCompass one has to read an encyclopedia sized tutorial and fumble their way through obscure XML (!) files to create their own visualizations. Let's just say, ease of use did not seem to be the goal at all.
