lttng-disable-event — Disable LTTng event rules
lttng disable-event command disables one or more event rules
previously enabled by the lttng-enable-event(1) command.
Event rules are always assigned to a channel when they are created. If
--channel option is omitted, the default channel named
channel0 is used.
--session option is omitted, the chosen channel is picked
from the current tracing session.
--all-events option is used, all the existing event rules
of the chosen domain are disabled. Otherwise, at least one event rule
to disable named EVENT must be specified.
--kernel option, the event source type can be specified
using one of the
--syscall options. See
lttng-enable-event(1) for more details about event source
Events can be disabled while tracing is active (use lttng-start(1) to make a tracing session active).
Disable event rules in the
java.util.logging (JUL) domain.
Disable event rules in the Linux kernel domain.
Disable event rules in the Apache log4j domain.
Disable event rules in the Python domain.
Disable event rules in the user space domain.
Linux kernel kretprobe. Only available with the
Linux kernel kprobe. Only available with the
Linux kernel system call. Only available with the
Linux kernel or application tracepoint. Only available
--kernel domain option (default Linux kernel
domain event source type).
Set to 1 to abort the process after the first error is encountered.
$HOME environment variable. Useful when the user
running the commands has a non-writable home directory.
Absolute path to the man pager to use for viewing help information
about LTTng commands (using lttng-help(1) or
lttng COMMAND --help).
Path in which the
session.xsd session configuration XML
schema may be found.
Full session daemon binary path.
--sessiond-path option has precedence over this
Note that the lttng-create(1) command can spawn an LTTng session daemon automatically if none is running. See lttng-sessiond(8) for the environment variables influencing the execution of the session daemon.
User LTTng runtime configuration.
This is where the per-user current tracing session is stored between executions of lttng(1). The current tracing session can be set with lttng-set-session(1). See lttng-create(1) for more information about tracing sessions.
Default output directory of LTTng traces. This can be overridden
--output option of the lttng-create(1)
User LTTng runtime and configuration directory.
$LTTNG_HOME defaults to
$HOME when not explicitly set.
Command warning (something went wrong during the command)
If you encounter any issue or usability problem, please report it on the LTTng bug tracker.
Special thanks to Michel Dagenais and the DORSAL laboratory at École Polytechnique de Montréal for the LTTng journey.
Also thanks to the Ericsson teams working on tracing which helped us greatly with detailed bug reports and unusual test cases.
