| | 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. |
