17 | DESCRIPTION | |
18 | ----------- | |
19 | The `lttng disable-channel` command disables one or more channels | |
484b2a0c | 20 | previously enabled with the man:lttng-enable-channel(1) command. |

22 | A channel always belongs to a tracing session (see man:lttng-create(1) |
23 | to create a tracing session). Without the option:--session option, the | |
24 | `disable-channel` command disables one or more channels of the current | |
25 | tracing session (see man:lttng-create(1) and man:lttng-set-session(1) to | |
26 | learn more about the current tracing session). | |

28 | The `disable-channel` command disables one channel per 'CHANNEL' |
29 | argument. | |
30 | ||
31 | As of LTTng{nbsp}{lttng_version}, you may :not: enable a disabled | |
32 | channel once its tracing session has ben started (see | |
33 | man:lttng-start(1)) at least once. | |
