To perform kernel tracing, lttng-sessiond daemon MUST be run as root since
it must load kernel modules.

Now to interact with and control a kernel tracing session one must be part of
the "tracing" group or be root.

Again, from the doc [1]:

"The default tracing group name is *tracing*; you can set it to something else with the --group option when you start the root session daemon."

[1] https://lttng.org/docs/v2.10/#doc-start-sessiond

At this point you can google:
    how to create group on linux?
    how to add user to a group on linux?

Cheers.
