Синопсис (Synopsis)

lttng [GENERAL OPTIONS] version


Описание (Description)

The lttng version command outputs the version of LTTng-tools.

The output of lttng version is broken down into the following parts:

• Major, minor, and patch numbers

• Git commit information, if available

• Release name with its description

• LTTng project's website URL

• License information


Параметры (Options)

General options are described in lttng(1).

Program information -h, --help Show command help.

This option, like lttng-help(1), attempts to launch /usr/bin/man to view the command's man page. The path to the man pager can be overridden by the LTTNG_MAN_BIN_PATH environment variable.

--list-options List available command options.


Переменные окружения (Environment variables)

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

LTTNG_HOME Overrides the $HOME environment variable. Useful when the user running the commands has a non-writable home directory.

LTTNG_MAN_BIN_PATH Absolute path to the man pager to use for viewing help information about LTTng commands (using lttng-help(1) or lttng COMMAND --help).

LTTNG_SESSION_CONFIG_XSD_PATH Path in which the session.xsd session configuration XML schema may be found.

LTTNG_SESSIOND_PATH Full session daemon binary path.

The --sessiond-path option has precedence over this environment variable.

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.


Файлы (Files)

$LTTNG_HOME/.lttngrc 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.

$LTTNG_HOME/lttng-traces Default output directory of LTTng traces. This can be overridden with the --output option of the lttng-create(1) command.

$LTTNG_HOME/.lttng User LTTng runtime and configuration directory.

$LTTNG_HOME/.lttng/sessions Default location of saved user tracing sessions (see lttng-save(1) and lttng-load(1)).

/usr/local/etc/lttng/sessions System-wide location of saved tracing sessions (see lttng-save(1) and lttng-load(1)).

Note $LTTNG_HOME defaults to $HOME when not explicitly set.
