  17 DESCRIPTION
  18 -----------
  19 The `lttng start` command starts a tracing session, that is, it
  20 activates the LTTng tracers for:
  21
  22 With the 'SESSION' argument::
  23     The tracing session named 'SESSION'.
  24
  25 Without the 'SESSION' argument::
  26     The current tracing session (see man:lttng-concepts(7) to learn more
  27     about the current tracing session).
  28
  29 See man:lttng-concepts(7) to learn more about tracing sessions.
  30
  31 The selected tracing session must be inactive (stopped). A tracing
  32 session is inactive on creation (see man:lttng-create(1)).
  33
  34 A `start-session` trigger action can also start a tracing session
  35 (see man:lttng-add-trigger(1)).
  36
  37 Stop an active tracing session with the man:lttng-stop(1) command.
