   format(record)

      Format the specified record as text.

      The record's attribute dictionary is used as the operand to a
      string formatting operation which yields the returned string.
      Before formatting the dictionary, a couple of preparatory steps
      are carried out. The message attribute of the record is computed
      using LogRecord.getMessage(). If the formatting string uses the
      time (as determined by a call to usesTime(), formatTime() is
      called to format the event time. If there is exception
      information, it is formatted using formatException() and
      appended to the message.

   Consistently format exception information

fail2ban.helpers.getLogger(name)

   Get logging.Logger instance with Fail2Ban logger name convention

fail2ban.helpers.getVerbosityFormat(verbosity, fmt=' %(message)s', addtime=True, padding=True)

   Custom log format for the verbose runs
