As of now, you can't enable system calls tracing one by one (sys_open is a system call), it's either all of them or none. So if you want sched_switch and all the syscalls you have to do : lttng enable-event -k sched_switch lttng enable-event -k --syscall -a Have fun, Julien _______________________________________________ lttng-dev mailing list [email protected] http://lists.lttng.org/cgi-bin/mailman/listinfo/lttng-dev
