lttng-metadata - Manage an LTTng tracing session's metadata generation
lttng [GENERAL OPTIONS] metadata regenerate [--session=SESSION]
This command is deprecated; it has been replaced by lttng regenerate metadata (see lttng-regenerate(1)).
General options are described in lttng(1).
-s SESSION, --session=SESSION
-h, --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
The lttng metadata regenerate command can only be used on kernel and user space tracing sessions (using per-user buffering), in non-live mode.
See lttng-enable-channel(1) for more information about buffering schemes and lttng-create(1) for more information about the different tracing session modes.
LTTNG_ABORT_ON_ERROR
LTTNG_HOME
LTTNG_MAN_BIN_PATH
LTTNG_SESSION_CONFIG_XSD_PATH
LTTNG_SESSIOND_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.
$LTTNG_HOME/.lttngrc
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
$LTTNG_HOME/.lttng
$LTTNG_HOME/.lttng/sessions
/usr/local/etc/lttng/sessions
$LTTNG_HOME defaults to $HOME when not explicitly set.
