NAME

       lttng-status - Get the current LTTng tracing session's status

SYNOPSIS

       lttng [GENERAL OPTIONS] status

DESCRIPTION

       The lttng status command shows the status of the current tracing session.

       This command is the exact equivalent of:

           $ lttng list CURSESSION

       where CURSESSION is the name of the current tracing session. Use lttng-set-session(1) to set the current
       tracing session.

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.

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.

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.

EXIT STATUS

       0
           Success

       1
           Command error

       2
           Undefined command

       3
           Fatal error

       4
           Command warning (something went wrong during the command)
