No at this point, sorry.
Eventually, this could be done once the filter bytecode gets ported from
LTTng-UST to LTTng-modules, but we have no ETA on this at this point.
Thanks,
Mathieu

Hi Mathieu,
Thank you for your reply. Then I probably will filter the tracing info by
post processing. I will keep exploring this great tool. It is very useful.
Thanks again.
Regards,
Rui

Hi,
I just start using LTTng for my project. I found the system call tracing is
verbose. What if I only want have one or several particular syscalls
logged, how could I do that? Is there an easy way to do this like for
kernel events by "lttng enable-event sched_switch -k."?
Thank you very much.
Regards,
Rui
