| 10 | SYNOPSIS |
| 11 | -------- |
| 12 | [verse] |
| 13 | *lttng* ['linkgenoptions:(GENERAL OPTIONS)'] *disable-event* |
| 14 | (option:--kernel [option:--probe | option:--function | option:--syscall] | |
| 15 | option:--userspace | option:--jul | option:--log4j | option:--python) |
| 16 | [option:--session='SESSION'] [option:--channel='CHANNEL'] |
| 17 | (option:--all-events | 'EVENT'[,'EVENT']...) |
| 18 | |
| 19 | DESCRIPTION |
| 20 | ----------- |
| 21 | The `lttng disable-event` command disables one or more event rules |
| 22 | previously enabled by the man:lttng-enable-event(1) command. |
| 23 | |
| 24 | Event rules are always assigned to a channel when they are created. If |
| 25 | the option:--channel option is omitted, the default channel named |
| 26 | `channel0` is used. |
| 27 | |
| 28 | If the option:--session option is omitted, the chosen channel is picked |
| 29 | from the current tracing session. |
| 30 | |
| 31 | If the option:--all-events option is used, all the existing event rules |
| 32 | of the chosen domain are disabled. Otherwise, at least one event rule |
| 33 | to disable named 'EVENT' must be specified. |
| 34 | |
| 35 | With the option:--kernel option, the event source type can be specified |
| 36 | using one of the option:--tracepoint, option:--probe, |
| 37 | option:--function, or option:--syscall options. See |
| 38 | man:lttng-enable-event(1) for more details about event source |
| 39 | types. |
| 40 | |
| 41 | Events can be disabled while tracing is active |
| 42 | (use man:lttng-start(1) to make a tracing session active). |
