}

LogConfig is the log envconfig of node

func GetDefLogConf

func GetDefLogConf() *LogConf

func LoadLogConf

func LoadLogConf(cfgFile string) (*LogConf, error)

type LogDriver

type LogDriver interface {
	Fatal(msg string, ctx ...interface{})
	Error(msg string, ctx ...interface{})
	Warn(msg string, ctx ...interface{})
	Info(msg string, ctx ...interface{})
	Debug(msg string, ctx ...interface{})
}

LogDriver 底层日志库约束接口

func OpenMLog

func OpenMLog(lc *LogConf, logDir string) (LogDriver, error)

OpenMLog create and open log stream using LogConfig

type Logger

type Logger interface {
	GetLogId() string
	SetCommField(key string, value interface{})
	SetInfoField(key string, value interface{})
	Fatal(msg string, ctx ...interface{})
	Error(msg string, ctx ...interface{})
	Warn(msg string, ctx ...interface{})
	Info(msg string, ctx ...interface{})
	Debug(msg string, ctx ...interface{})
}

type LoggerImpl

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

func NewLogger

type Lvl

type Lvl int

Lvl is a type for predefined log levels.

const (
	LvlFatal Lvl = iota
	LvlError
	LvlWarn
	LvlInfo
	LvlDebug
)

List of predefined log Levels

func LvlFromString

func LvlFromString(lvlString string) Lvl

LvlFromString returns the appropriate Lvl from a string name. Useful for parsing command line args and configuration files.
