Field types for structured logging. Most fields are lazily marshaled so it is inexpensive to add fields to disabled log statements.

Functions

func Configure 

func Configure(cfg Config) error

Configure configures the logp package.

func DevelopmentSetup 

func DevelopmentSetup(options ...Option) error

DevelopmentSetup configures the logger in development mode at debug level. By default the output goes to stderr.

func HasSelector 

func HasSelector(selector string) bool

HasSelector returns true if the given selector was explicitly set.

func IsDebug 

func IsDebug(selector string) bool

IsDebug returns true if the given selector would be logged. Deprecated: Use logp.NewLogger.

func ObserverLogs 

func ObserverLogs() *observer.ObservedLogs

ObserverLogs provides the list of logs generated during the observation process.

func SetLevel 

func SetLevel(lv Level)

SetLevel 动态设置日志等级

func Sync 

func Sync() error

Sync flushes any buffered log entries. Applications should take care to call Sync before exiting.

func TestingSetup 

func TestingSetup(options ...Option) error

TestingSetup configures logging by calling DevelopmentSetup if and only if verbose testing is enabled (as in 'go test -v').

Types

type Config 

type Config struct {
	Name      string      // Name of the Logger (for default file name).
	JSON      bool        // Write logs as JSON.
	Level     Level       // Logging level (error, warning, info, debug).
	Metas     []zap.Field // Root Logger Metas
	Selectors []string    // Selectors for debug level logging.

	ToStderr   bool
	ToSyslog   bool
	ToFiles    bool
	ToEventLog bool

	Files FileConfig
	// contains filtered or unexported fields
}

Config contains the configuration options for the logger. To create a Config from a common.Config use logp/config.Build.

func DefaultConfig 

func DefaultConfig() Config

DefaultConfig returns the default config options.

type FileConfig 

type FileConfig struct {
	Path            string
	Name            string
	MaxSize         uint
	MaxBackups      uint
	Permissions     uint32
	Interval        time.Duration
	RotateOnStartup bool
	RedirectStderr  bool
}

FileConfig contains the configuration options for the file output.

type Level 

type Level int8

Level is a logging priority. Higher levels are more important. 

const (
	DebugLevel Level = iota - 1
	InfoLevel
	WarnLevel
	ErrorLevel
	PanicLevel
	FatalLevel
)

Logging levels.

func NewLevel 

func NewLevel(str string) (Level, error)

NewLevel 更加string生成Level

func (Level) Enabled 

func (l Level) Enabled(level Level) bool

Enabled returns true if given level is enabled.

func (Level) String 

func (l Level) String() string

String returns the name of the logging level.

func (*Level) Unpack 

func (l *Level) Unpack(str string) error

Unpack unmarshals a level string to a Level. This implements ucfg.StringUnpacker.

type LogOption 

type LogOption = zap.Option

LogOption configures a Logger.

type Logger 

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

Logger logs messages to the configured output.

func L 

func L() *Logger

L returns an unnamed global logger.

func NewLogger 

func NewLogger(selector string, options ...LogOption) *Logger

NewLogger returns a new Logger labeled with the name of the selector. This should never be used from any global contexts, otherwise you will receive a no-op Logger. This is because the logp package needs to be initialized first. Instead create new Logger instance that your object reuses. Or if you need to log from a static context then you may use logp.L().Infow(), for example.

func (*Logger) DPanic 

func (l *Logger) DPanic(args ...interface{})

DPanic uses fmt.Sprint to construct and log a message. In development, the logger then panics.

DPanicf uses fmt.Sprintf to log a templated message. In development, the logger then panics.

func (*Logger) DPanicw 

func (l *Logger) DPanicw(msg string, fields ...logger.Field)

DPanicw logs a message with some additional context. The logger panics only in Development mode. The additional context is added in the form of key-value pairs. The optimal way to write the value to the log message will be inferred by the value's type. To explicitly specify a type you can pass a Field such as logp.Stringer.

func (*Logger) Debug 

func (l *Logger) Debug(args ...interface{})

Debug uses fmt.Sprint to construct and log a message.

func (*Logger) Debugf 

func (l *Logger) Debugf(format string, args ...interface{})

Debugf uses fmt.Sprintf to construct and log a message.

func (*Logger) Debugw 

func (l *Logger) Debugw(msg string, fields ...logger.Field)

Debugw logs a message with some additional context. The additional context is added in the form of key-value pairs. The optimal way to write the value to the log message will be inferred by the value's type. To explicitly specify a type you can pass a Field such as logp.Stringer.

func (*Logger) Error 

func (l *Logger) Error(args ...interface{})

Error uses fmt.Sprint to construct and log a message.

func (*Logger) Errorf 

func (l *Logger) Errorf(format string, args ...interface{})

Errorf uses fmt.Sprintf to log a templated message.

func (*Logger) Errorw 

func (l *Logger) Errorw(msg string, fields ...logger.Field)

Errorw logs a message with some additional context. The additional context is added in the form of key-value pairs. The optimal way to write the value to the log message will be inferred by the value's type. To explicitly specify a type you can pass a Field such as logp.Stringer.

func (*Logger) Fatal 

func (l *Logger) Fatal(args ...interface{})

Fatal uses fmt.Sprint to construct and log a message, then calls os.Exit(1).
