NAME

SYNOPSIS

DESCRIPTION

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

Success

Command error

Undefined command

Fatal error

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
