Right now, I need to include process id and thread id for each event in order to generate process/thread indexed view of the traces. Is there a way that I can store per-process events into a specific buffer without mixing the events with other events that are generated on the same CPU? The same thing for per-thread events, I would like lttng or CTF to allow to store per-thread events in a specific buffer without mixing the events with other events on the same CPU channel. With that feature, I do not need to store process id and thread id in each event and then need to query all the events in order to collect per-process or per-thread event.
