optional arguments:
  -h, --help            show this help message and exit
  --agent-join-timeout AGENT_JOIN_TIMEOUT
                        Timeout to treat agent as join failed in seconds,
                        defaults to env[SHAKER_AGENT_JOIN_TIMEOUT] (time
                        between stack deployment and start of scenario
                        execution).
  --agent-loss-timeout AGENT_LOSS_TIMEOUT
                        Timeout to treat agent as lost in seconds, defaults to
                        env[SHAKER_AGENT_LOSS_TIMEOUT]
  --artifacts-dir ARTIFACTS_DIR
                        If specified, directs Shaker to store there all its
                        artifacts (output, report, subunit and book). Defaults
                        to env[SHAKER_ARTIFACTS_DIR].
  --book BOOK           Generate report in ReST format and store it into the
                        specified folder, defaults to env[SHAKER_BOOK].
  --cleanup-on-error    Clean up the heat-stack upon any error occurred 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. Defaults to None.
  --debug, -d           If set to true, the logging level will be set to DEBUG
                        instead of the default INFO level.
  --dns-nameservers DNS_NAMESERVERS
                        Comma-separated list of IPs of the DNS nameservers for
                        the subnets. If no value is provided defaults to
                        Google Public DNS.
  --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. Note that when
                        logging configuration files are used then all logging
                        configuration is set in the configuration file and
                        other logging configuration options are ignored (for
                        example, logging_context_format_string).
  --log-date-format DATE_FORMAT
                        Defines the format string for %(asctime)s in log
                        records. Default: None . This option is ignored if
                        log_config_append is set.
  --log-dir LOG_DIR, --logdir LOG_DIR
                        (Optional) The base directory used for relative
                        log_file paths. This option is ignored if
                        log_config_append is set.
  --log-file PATH, --logfile PATH
                        (Optional) Name of log file to send logging output to.
                        If no default is set, logging will go to stderr as
                        defined by use_stderr. This option is ignored if
                        log_config_append is set.
  --matrix MATRIX       Set the matrix of parameters for the scenario. The
                        value is specified in YAML format. E.g. to override
                        the scenario duration one may provide: "{time: 10}",
                        or to override list of hosts: "{host:[ping.online.net,
                        iperf.eenet.ee]}". When several parameters are
                        overridden all combinations are tested

  --os-project-name <auth-project-name>
                        Authentication project name. This option is mutually
                        exclusive with --os-tenant-name. Defaults to
                        env[OS_PROJECT_NAME].
  --os-region-name <auth-region-name>

  --output OUTPUT       File for output in JSON format, defaults to
                        env[SHAKER_OUTPUT]. If it is empty, then output will

                        Address for server connections (host:port), defaults
                        to env[SHAKER_SERVER_ENDPOINT].
  --subunit SUBUNIT     Subunit stream file name, defaults to
                        env[SHAKER_SUBUNIT].
  --syslog-log-facility SYSLOG_LOG_FACILITY
                        Syslog facility to receive log lines. This option is
                        ignored if log_config_append is set.
  --use-syslog          Use syslog for logging. Existing syslog format is
                        DEPRECATED and will be changed later to honor RFC5424.
                        This option is ignored if log_config_append is set.
  --verbose, -v         If set to false, the logging level will be set to
                        WARNING instead of the default INFO level.
  --watch-log-file      Uses logging handler designed to watch file system.
                        When log file is moved or removed this handler will
                        open a new log file with specified path
                        instantaneously. It makes sense only if log_file
                        option is specified and Linux platform is used. This
                        option is ignored if log_config_append is set.
