SYNOPSIS

       lttng [GENERAL OPTIONS] metadata regenerate [--session=SESSION]

DESCRIPTION

       Warning

           This command is deprecated; it’s been replaced with lttng regenerate metadata (see lttng-
           regenerate(1)).

OPTIONS

       See lttng(1) for GENERAL OPTIONS.

       -s SESSION, --session=SESSION
           Manage the metadata generation of the recording session named SESSION instead of the current
           recording session (see lttng-concepts(7) to learn more about the current recording session).

   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.
