8 lttng-disable-event - Disable LTTng recording event rules
13 Disable one or more recording event rules matching Linux kernel
17 *lttng* ['linkgenoptions:(GENERAL OPTIONS)'] *disable-event* option:--kernel
18 [option:--tracepoint | option:--syscall | option:--probe | option:--function]
19 (option:--all-events | 'NAME'[,'NAME']...)
20 [option:--session='SESSION'] [option:--channel='CHANNEL']
22 Disable one or more recording event rules matching user space
23 tracepoint or Java/Python logging events:
26 *lttng* ['linkgenoptions:(GENERAL OPTIONS)'] *disable-event*
27 (option:--userspace | option:--jul | option:--log4j | option:--python) [option:--tracepoint]
28 (option:--all-events | 'NAME'[,'NAME']...)
29 [option:--session='SESSION'] [option:--channel='CHANNEL']
34 The `lttng disable-event` command disables one or more enabled recording
35 event rules previously created with the man:lttng-enable-event(1)
36 command which belong to:
38 With the option:--session='SESSION' option::
39 The tracing session named 'SESSION'.
41 Without the option:--session option::
42 The current tracing session (see man:lttng-concepts(7) to learn more
43 about the current tracing session).
45 With the option:--channel='CHANNEL' option::
46 The channel named 'CHANNEL'.
48 Without the option:--channel option::
49 The channel named `channel0`.
51 See man:lttng-concepts(7) to learn more about recording event rules.
53 As of LTTng{nbsp}{lttng_version}, the `disable-event` command can only
54 find recording event rules to disable by their instrumentation point
55 type and event name conditions. Therefore, you cannot disable recording
56 event rules having a specific instrumentation point log level condition,
59 List the recording event rules of a given tracing session
60 and/or channel with the man:lttng-list(1) command.
62 Without the option:--all-events option, the `disable-event` command
63 disables one recording event rule per 'NAME' argument. 'NAME' is the
64 exact event name condition pattern of the recording event rule to
65 disable, as listed in the output of `lttng list` (see
68 You may disable an enabled recording event rule regardless of the
69 activity (started or stopped) of its tracing session (see
70 man:lttng-start(1) and man:lttng-stop(1)).
