Hi I'm afraid I'm still struggling with getting started with lttng. To recap, I want to use lttng + TraceCompass to monitor the scheduling of threads in my multi-threaded C++ application on Ubuntu.
Here is my session: $ sudo pkill lttng-sessiond $ sudo lttng-sessiond Error: Already running daemon. $ lttng create demo_session Spawning a session daemon Session demo_session created. Traces will be written in /home/<snip>/lttng-traces/demo_session-20160915-152653 <snip>:~$ PERROR [14956/14964]: bind inet: Address already in use (in lttcomm_bind_inet_sock() at inet.c:109) Warning: An other session daemon is using this JUL port. JUL support will be deactivated not interfering with the tracing. $ sudo lttng enable-event -k sched_switch -s demo_session Error: Event sched_switch: Session name not found (channel channel0, session demo_session) Warning: Some command(s) went wrong As you can see, each of these command generated a warning or error. Please will you suggest where I am going wrong?
