| 10 | SYNOPSIS |
| 11 | -------- |
| 12 | [verse] |
| 13 | *lttng* ['linkgenoptions:(GENERAL OPTIONS)'] *disable-channel* (option:--kernel | option:--userspace) |
| 14 | [option:--session='SESSION'] 'CHANNEL'[,'CHANNEL']... |
| 15 | |
| 16 | |
| 17 | DESCRIPTION |
| 18 | ----------- |
| 19 | The `lttng disable-channel` command disables one or more channels |
| 20 | previously enabled by the linklttng:lttng-enable-channel(1) command. |
| 21 | |
| 22 | A channel is always contained in a tracing session |
| 23 | (see linklttng: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. |
