17 | DESCRIPTION | |
18 | ----------- | |
19 | The `lttng disable-channel` command disables one or more channels | |
7c1a4458 | 20 | previously enabled by the man:lttng-enable-channel(1) command. |
4bf0a332 PP |
21 | |
22 | A channel is always contained in a tracing session | |
7c1a4458 | 23 | (see man:lttng-create(1) for creating a tracing session). The |
4bf0a332 PP |
24 | session in which a channel is disabled using `lttng disable-channel` can |
25 | be specified using the option:--session option. If the option:--session | |
26 | option is omitted, the current tracing session is targeted. | |
27 | ||
28 | Note that re-enabling a disabled channel once its tracing session | |
29 | has been active at least once is currently not supported. | |
