Read the doc. [1]

[1] https://lttng.org/docs/v2.10/#doc-tracing-the-linux-kernel
[2] https://lttng.org/docs/v2.10/#doc-tracing-group

It mostly depends on how lttng was installed since some ways of installing take
care of some steps for you.

The error message is pretty self explanatory. You both need a sessiond running
as root and the controlling user be either root or part of the "tracing" user
group.
