We use this package, these are the levels:

uber-go/zap/blob/1ae5819539453056267ba3033697df2b231e8af8/zapcore/level.go#L180


      
          func (l *Level) UnmarshalText(text []byte) error {
          	if l == nil {
          		return errUnmarshalNilLevel
          	}
          	if !l.unmarshalText(text) && !l.unmarshalText(bytes.ToLower(text)) {
          		return fmt.Errorf("unrecognized level: %q", text)
          	}
          	return nil
          }
          
          
func (l *Level) unmarshalText(text []byte) bool {
          	switch string(text) {
          	case "debug", "DEBUG":
          		*l = DebugLevel
          	case "info", "INFO", "": // make the zero value useful
          		*l = InfoLevel
          	case "warn", "WARN":
          		*l = WarnLevel
          	case "error", "ERROR":
          		*l = ErrorLevel
          	case "dpanic", "DPANIC":

I prefer to set these arguments on the command-line rather than the config file:

docker run -it storjlabs/storagenode:latest --log.level=error

To see all available storagenode arguments you can run:

docker run -it storjlabs/storagenode:latest --help

But I agree some of them need better documentation. PR welcome for here private/logging.go at 79135887c9bef0154d32fd1a26c5f0a25905acfa · storj/private · GitHub
