NAME

       lttng-remove-trigger - Remove an LTTng trigger

SYNOPSIS

       lttng [GENERAL OPTIONS] remove-trigger [--owner-uid=UID] NAME

DESCRIPTION

       The lttng remove-trigger command removes the trigger named NAME.

       See lttng-concepts(7) to learn more about LTTng triggers.

       List the triggers of your Unix user, or of all users if your Unix user is root, with the
       lttng-list-triggers(1) command.

       The remove-trigger command removes a trigger which belong to your Unix user. If your Unix
       user is root, you can remove the trigger of another user with the --owner-uid option.

       See the “EXAMPLES” section below for usage examples.

OPTIONS

   Identification
       --owner-uid=UID
           Remove the trigger named NAME of the Unix user having the user ID UID.

           You may only use this option if your Unix user is root.

   Program information
       -h, --help
           Show help.

           This option attempts to launch /usr/bin/man to view this manual page. Override the
           manual pager path with the LTTNG_MAN_BIN_PATH environment variable.

       --list-options
           List available command options and quit.

EXIT STATUS

       0
           Success

       1
           Command error

       2
           Undefined command

       3
           Fatal error

       4
           Command warning (something went wrong during the command)

ENVIRONMENT

       LTTNG_ABORT_ON_ERROR
           Set to 1 to abort the process after the first error is encountered.

       LTTNG_HOME
           Path to the LTTng home directory.

           Defaults to $HOME.

           Useful when the Unix user running the commands has a non-writable home directory.

       LTTNG_MAN_BIN_PATH
           Absolute path to the manual pager to use to read the LTTng command-line help (with
           lttng-help(1) or with the --help option) instead of /usr/bin/man.

       LTTNG_SESSION_CONFIG_XSD_PATH
           Path to the directory containing the session.xsd recording session configuration XML
           schema.

       LTTNG_SESSIOND_PATH
           Absolute path to the LTTng session daemon binary (see lttng-sessiond(8)) to spawn from
           the lttng-create(1) command.

           The --sessiond-path general option overrides this environment variable.

FILES

       $LTTNG_HOME/.lttngrc
           Unix user’s LTTng runtime configuration.

           This is where LTTng stores the name of the Unix user’s current recording session
           between executions of lttng(1).  lttng-create(1) and lttng-set-session(1) set the
           current recording session.

       $LTTNG_HOME/lttng-traces
           Default output directory of LTTng traces in local and snapshot modes.

           Override this path with the --output option of the lttng-create(1) command.

       $LTTNG_HOME/.lttng
           Unix user’s LTTng runtime and configuration directory.

       $LTTNG_HOME/.lttng/sessions
           Default directory containing the Unix user’s saved recording session configurations
           (see lttng-save(1) and lttng-load(1)).

       /etc/lttng/sessions
           Directory containing the system-wide saved recording session configurations (see
           lttng-save(1) and lttng-load(1)).

       Note
           $LTTNG_HOME defaults to the value of the HOME environment variable.

EXAMPLES

       Example 1. Remove a trigger.

               $ lttng remove-trigger my-trigger

       Example 2. Remove a trigger as another Unix user.

           The command line below removes a trigger as the mireille Unix user.

           Your Unix user must be root to use the --owner-uid option.

               $ lttng remove-trigger --owner-uid=$(id --user mireille) \
                                      my-trigger
