  16 DESCRIPTION
  17 -----------
  18 The `lttng stop` command stops the various LTTng tracers for a given
  19 active tracing session.
  20
  21 Stopping the LTTng tracers has the effect that all enabled event rules
  22 within enabled channels cannot make event sources _emit_ trace events
  23 anymore.
  24
  25 A tracing session with no running tracers is said to be _inactive_.
  26 Inactive tracing sessions can be set active using the
  27 man:lttng-start(1) command.
  28
  29 If 'SESSION' is omitted, the LTTng tracers are stopped for the current
  30 tracing session (see man:lttng-create(1) for more information
  31 about the current tracing session). Otherwise, they are stopped for the
  32 existing tracing session named 'SESSION'. `lttng list`
  33 outputs all the existing tracing sessions (see man:lttng-list(1)).
  34
  35 By default, the `lttng stop` command ensures that the tracing session's
  36 trace data is valid before returning to the prompt. With the
  37 option:--no-wait option, the command finishes immediately, hence a local
  38 trace might not be valid when the command is done. In this case, there
  39 is no way to know when the trace becomes valid.
