Functions

func SetInternalLogger

func SetInternalLogger(l Logger)

SetInternalLogger sets logger for quark-go framework internal logging. Internal logger is required and default implementation is base on "github.com/Sirupsen/logrus" library.

Types

type Fields

type Fields map[string]interface{}

Fields represents map between log parameter name and value.

type Level

type Level uint8

Level represents logging level.

const (
	// PanicLevel represents Panic logging level.
	PanicLevel Level = iota
	// FatalLevel represents Fatal logging level.
	FatalLevel
	// ErrorLevel represents Error logging level.
	ErrorLevel
	// WarningLevel represents Warning logging level.
	WarningLevel
	// InfoLevel represents Panic Info level.
	InfoLevel
	// DebugLevel represents Debug logging level.
	DebugLevel
)

type Logger

type Logger interface {
	Panic(args ...interface{})
	PanicWithFields(fields Fields, args ...interface{})

	Fatal(args ...interface{})
	FatalWithFields(fields Fields, args ...interface{})

	Error(args ...interface{})
	ErrorWithFields(fields Fields, args ...interface{})

	Warning(args ...interface{})
	WarningWithFields(fields Fields, args ...interface{})

	Info(args ...interface{})
	InfoWithFields(fields Fields, args ...interface{})

	Debug(args ...interface{})
	DebugWithFields(fields Fields, args ...interface{})

	SetLevel(level Level)
	IsLevel(level Level) bool
}

Logger represents logging mechanism.

func Log

func Log() Logger

Log returns internally configured logger. By default it is set to "github.com/Sirupsen/logrus" library logger.

func NewLogger

func NewLogger() Logger

NewLogger creates logger based on logrus library. It is default logger implementation for internal logging.

type LogrusLogger

type LogrusLogger struct {
}

LogrusLogger represents loging mechanism based on "github.com/Sirupsen/logrus" library.

func (LogrusLogger) Debug

func (logger LogrusLogger) Debug(args ...interface{})
