–config-dir DIR

Path to a config directory to pull *.conf files from. This file set is sorted, 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. This means that configuration from files in a specified config-dir will always take precedence over configuration from files specified by –config-file, regardless to argument order.

–config-file PATH

Path to a config file to use. Multiple config files can be specified by using this flag multiple times, for example, –config-file <file1> –config-file <file2>. Values in latter files take precedence.

–log-config-append PATH –log-config PATH

The name of logging configuration file. It does not disable existing loggers, but just appends specified logging configuration to any other existing logging options. Please see the Python logging module documentation for details on logging configuration files. The log-config name for this option is depcrecated.

–log-format FORMAT

A logging.Formatter log message format string which may use any of the available logging.LogRecord attributes. Default: None

–log-date-format DATE_FORMAT

Format string for %(asctime)s in log records. Default: None

–log-file PATH, –logfile PATH

(Optional) Name of log file to output to. If not set, logging will go to stdout.

–log-dir LOG_DIR, –logdir LOG_DIR

(Optional) The directory to keep log files in (will be prepended to –log-file)
