17 DESCRIPTION
18 -----------
19 The `lttng disable-channel` command disables one or more channels
20 previously enabled by the man:lttng-enable-channel(1) command.
21
22 A channel is always contained in a tracing session
23 (see man:lttng-create(1) for creating a tracing session). The
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.
