Hi Mosleh,
It's expected to not see any event when running lttng list -u if no
lttng-ust instrumented applications are running.

What are the exact lttng commands you are running to see those
unexpected events?

Thank you,

Once I load the built image onto my system and start a session daemon, I try to list all available userspace events (using lttng list -u), but no events show up.
