Types

type JSONLog

type JSONLog struct {
	// contains filtered or unexported fields
}

JSONLog is custom logger type. It holds the output destination that the log entries will be written to, the minimum severity level that log entries will be written for, plus a mutex for coordinating the writes.

func New

func New(out io.Writer, minLevel logger.Level) *JSONLog

New returns a new JSONLog instance which writes log entries at or above a minimum severity level to a specific output destination.

func (*JSONLog) PrintDebug

func (l *JSONLog) PrintDebug(message string, properties map[string]string)

PrintDebug is a helper method to write DEBUG level log entries.

func (*JSONLog) PrintError

func (l *JSONLog) PrintError(err error, properties map[string]string)

PrintError is a helper method to write ERROR level log entries.

func (*JSONLog) PrintFatal

func (l *JSONLog) PrintFatal(err error, properties map[string]string)

PrintFatal is a helper method to write FATAL level log entries.

func (*JSONLog) PrintInfo

func (l *JSONLog) PrintInfo(message string, properties map[string]string)

PrintInfo is a helper method to write INFO level log entries.

func (*JSONLog) Write

func (l *JSONLog) Write(message []byte) (n int, err error)

Write writes a log entry at the ERROR level with no additional properties. It is implemented to satisfy the io.Writer interface.
