Log

This is the global logger for all micro based libraries which makes use of github.com/go-log/log.

It defaults the logger to the stdlib log implementation.

Set Logger

Set the logger for micro libraries

// import go-micro/util/log
import "git.xswitch.cn/xswitch/xctrl/stack/util/log"

// SetLogger expects github.com/go-log/log.Logger interface
log.SetLogger(mylogger)

Types

type Level

type Level int

level is a log level

const (
	LevelFatal Level = iota
	LevelError
	LevelWarn
	LevelInfo
	LevelDebug
	LevelTrace
)

func GetLevel

func GetLevel() Level

GetLevel returns the current level

type LogLogger

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

func New

func New() *LogLogger

func (*LogLogger) Log

func (logger *LogLogger) Log(level int, v ...interface{})

func (*LogLogger) Logf

func (logger *LogLogger) Logf(level int, format string, v ...interface{})

type Logger

type Logger interface {
	// Log inserts a log entry.  Arguments may be handled in the manner
	// of fmt.Print, but the underlying logger may also decide to handle
	// them differently.
	Log(level int, v ...interface{})
	// Logf insets a log entry.  Arguments are handled in the manner of
	// fmt.Printf.
	Logf(level int, format string, v ...interface{})
}

Logger is a generic logging interface

func GetLogger

func GetLogger() Logger

GetLogger returns the local logger

type LoggerStruct

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

func NewLog
