The following command "lttng-sessiond -vvv" will necessarily fail since the
previous command " lttng create mysession" just spawned one.
Could you try these on a rebooted board as root:
(Make sure there is no sessiond running)
lttng-sessiond -vvv > sessiond.log 2>&1
lttng create
lttng enable-event -a -k
lttng start
sleep 1
lttng stop
lttng view
If on "lttng view" there is no events or any of the commands fail make sure
to include their output and the sessiond.log file so we can pinpoint the
problem.
