The command "lttng enable-event" allows to enable events for one loglevel or for a range of loglevels. However, the "lttng list session"-command doens't show what is actually enabled. It should be clear if a single loglevel is enabled or a range.

Consider the two commands:

lttng enable-event a* -u --loglevel TRACE_DEBUG_LINE
lttng enable-event b* -u --loglevel-only TRACE_DEBUG_LINE

For both commands the output shows basically the same information. For the first one it doesn't show that the events are enabled for a range. This needs to be improved.
