8 lttng-stop - Stop an LTTng recording session
14 *lttng* ['linkgenoptions:(GENERAL OPTIONS)'] *stop* [option:--no-wait] ['SESSION']
19 The `lttng stop` command stops a recording session, that is, it
20 deactivates the LTTng tracers for:
22 With the 'SESSION' argument::
23 The recording session named 'SESSION'.
25 Without the 'SESSION' argument::
26 The current recording session (see man:lttng-concepts(7) to learn more
27 about the current recording session).
29 See man:lttng-concepts(7) to learn more about recording sessions.
31 The selected recording session must be active (started; see
32 man:lttng-start(1)). A recording session is inactive on creation (see
35 A `stop-session` trigger action can also stop a recording session (see
36 man:lttng-add-trigger(1)).
38 Start an inactive recording session with the man:lttng-start(1) command.
40 By default, the `stop` command ensures that the trace data of the
41 selected recording session is valid before it exits. Make the command
42 exit immediately with the option:--no-wait option. In this case,
43 however, the traces(s) might not be valid when the command exits, and
44 there's no way to know when it/they becomes valid.
46 If LTTng archived the current trace chunk (see man:lttng-rotate(1) and
47 man:lttng-enable-rotation(1)) of the selected recording session at least
48 once during its lifetime, the `stop` command renames the current trace
49 chunk subdirectory and prints the renamed path. Although it's safe to
50 read the content of this renamed subdirectory while the recording
51 session remains inactive, it's :not: a trace chunk archive: you need to
52 destroy the recording session with man:lttng-destroy(1) or perform a
53 rotation with man:lttng-rotate(1) to archive it.
