Hi Jonathan Thanks, I had not logged out/in after joining the tracing group.
I now see: $ lttng create demo_session Session demo_session created. $ sudo lttng enable-event -k sched_switch -s demo_session Error: Event sched_switch: Kernel tracer not available (channel channel0, session demo_session) Warning: Some command(s) went wrong What do I need to install?
