| 8 | lttng-stop - Stop LTTng tracers | |
| 9 | ||

| 11 | SYNOPSIS | |
| 12 | -------- | |
| 13 | [verse] | |
| ce19b9ed | 14 | *lttng* ['linkgenoptions:(GENERAL OPTIONS)'] *stop* [option:--no-wait] ['SESSION'] |

| 17 | DESCRIPTION | |
| 18 | ----------- | |
| 19 | The `lttng stop` command stops the various LTTng tracers for a given | |
| 20 | active tracing session. | |
| 21 | ||
| 5de63f6d | 22 | Stopping the LTTng tracers has the effect that all enabled event rules |
| fb58d659 PP |
23 | within enabled channels cannot make event sources _emit_ trace events |
| 24 | anymore. | |
| 25 | ||
| 26 | A tracing session with no running tracers is said to be _inactive_. | |
| 27 | Inactive tracing sessions can be set active using the | |
| 7c1a4458 | 28 | man:lttng-start(1) command. |
| fb58d659 PP |
29 | |
| 30 | If 'SESSION' is omitted, the LTTng tracers are stopped for the current | |
| 7c1a4458 | 31 | tracing session (see man:lttng-create(1) for more information |
| fb58d659 PP |
32 | about the current tracing session). Otherwise, they are stopped for the |
| 33 | existing tracing session named 'SESSION'. `lttng list` | |
| 7c1a4458 | 34 | outputs all the existing tracing sessions (see man:lttng-list(1)). |
| fb58d659 PP |
35 | |
| 36 | By default, the `lttng stop` command ensures that the tracing session's | |
| 37 | trace data is valid before returning to the prompt. With the | |
| 38 | option:--no-wait option, the command finishes immediately, hence a local | |
| 39 | trace might not be valid when the command is done. In this case, there | |
| 40 | is no way to know when the trace becomes valid. | |

47 | Do not ensure that the chosen tracing session's trace data is valid |
