Hello
I'm a LTTNG newbie trying to write in my lttng session some "marker"  events with trace message from my program,by writing in /proc/lttng-logger file. But I can't see them and i don't know if they are really written in the session.I do this:
lttng enable-event -k ...kernel functions here...
lttng enable-event -k --syscall -all
lttng enable-event -k lttng_logger lttng enable-event -u my_program_name:'*' --all

With this syntax,after the start/destroy session I can't see either syscalls nor my user events in Eclipse tracecompass.But I see all kernel calls perfectly.

Why can't I see any syscalls? Is my syntax correct?Maybe my messages are there, but tracecompass hides them for whatever reason?Thank you
