    level = "emerg";
    silent = true;
    break;
  default:
    level = "debug";
    silent = false;
    break;
}

const options = {
  console: {
    level,
    silent,
    handleExceptions: true,
    format: format.combine(
      format.colorize(),
      format.splat(),
      format.printf(
        info => `${new Date().toISOString()} ${info.level}: ${info.message}`,
      ),
    ),
  },
};

const logger = createLogger({
  levels: config.syslog.levels,
  transports: [new transports.Console(options.console)],
  exitOnError: false,
});

module.exports = logger;
