| 7 | lttng-stop - Stop LTTng tracers | |
| 8 | ||

| 12 | [verse] | |

| 16 | DESCRIPTION | |
| 17 | ----------- | |
| 18 | The `lttng stop` command stops the various LTTng tracers for a given | |
| 19 | active tracing session. | |
| 20 | ||
| 5de63f6d | 21 | Stopping the LTTng tracers has the effect that all enabled event rules |
| fb58d659 PP |
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 | |
| 7c1a4458 | 27 | man:lttng-start(1) command. |

28 | |
| 29 | If 'SESSION' is omitted, the LTTng tracers are stopped for the current | |
| 7c1a4458 | 30 | tracing session (see man:lttng-create(1) for more information |
| fb58d659 PP |
31 | about the current tracing session). Otherwise, they are stopped for the |
| 32 | existing tracing session named 'SESSION'. `lttng list` | |
| 7c1a4458 | 33 | outputs all the existing tracing sessions (see man:lttng-list(1)). |
| fb58d659 PP |
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. | |

| 46 | Do not ensure that the chosen tracing session's trace data is valid | |
| 47 | before returning to the prompt. | |
