optional arguments:
  -h, --help            show this help message and exit
  --agent-join-timeout AGENT_JOIN_TIMEOUT
                        How long to wait for agents to join in seconds (time
                        between stack deployment and start of scenario
                        execution).
  --agent-loss-timeout AGENT_LOSS_TIMEOUT
                        Timeout to treat agent as lost in seconds
  --cleanup-on-error    Cleans up the heat-stack upon any error occured during
                        scenario execution.
  --config-dir DIR      Path to a config directory to pull *.conf files from.
                        This file set is sorted, so as to provide a
                        predictable parse order if individual options are
                        over-ridden. The set is parsed after the file(s)
                        specified via previous --config-file, arguments hence
                        over-ridden options in the directory take precedence.
  --config-file PATH    Path to a config file to use. Multiple config files
                        can be specified, with values in later files taking
                        precedence. The default files used are: None.
  --debug, -d           Print debugging output (set logging level to DEBUG
                        instead of default INFO level).
  --external-net EXTERNAL_NET
                        Name or ID of external network, defaults to
                        env[SHAKER_EXTERNAL_NET]. If no value provided then
                        Shaker picks any of available external networks.
  --flavor-name FLAVOR_NAME
                        Name of image flavor. The default is created by
                        shaker-image-builder.
  --image-name IMAGE_NAME
                        Name of image to use. The default is created by
                        shaker-image-builder.
  --log-config-append PATH, --log_config PATH
                        The name of a logging configuration file. This file is
                        appended to any existing logging configuration files.
                        For details about logging configuration files, see the
                        Python logging module documentation.
  --log-date-format DATE_FORMAT
                        Format string for %(asctime)s in log records. Default:
                        None .
  --log-dir LOG_DIR, --logdir LOG_DIR

                        file paths.
  --log-file PATH, --logfile PATH
                        (Optional) Name of log file to output to. If no
                        default is set, logging will go to stdout.
  --log-format FORMAT   DEPRECATED. A logging.Formatter log message format
                        string which may use any of the available
                        logging.LogRecord attributes. This option is
                        deprecated. Please use logging_context_format_string
                        and logging_default_format_string instead.
