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.

Types

type Config

type Config struct {
	Beat      string   `config:",ignore"`   // Name of the Beat (for default file name).
	JSON      bool     `config:"json"`      // Write logs as JSON.
	Level     Level    `config:"level"`     // Logging level (error, warning, info, debug).
	Selectors []string `config:"selectors"` // Selectors for debug level logging.

	ToStderr   bool `config:"to_stderr"`
	ToSyslog   bool `config:"to_syslog"`
	ToFiles    bool `config:"to_files"`
	ToEventLog bool `config:"to_eventlog"`

	Files FileConfig `config:"files"`
	// 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 `config:"path"`
	Name        string `config:"name"`
	MaxSize     uint   `config:"rotateeverybytes" validate:"min=1"`
	MaxBackups  uint   `config:"keepfiles" validate:"max=1024"`
	Permissions uint32 `config:"permissions"`
}

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
	CriticalLevel // Critical exists only for config backward compatibility.
)

Logging levels.

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 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 (instead create "per instance" loggers).

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.

func (*Logger) DPanicf

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

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

func (*Logger) DPanicw

func (l *Logger) DPanicw(msg string, keysAndValues ...interface{})

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{})

Warnw 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) With

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

With creates a child logger and adds structured context to it. Fields added to the child don't affect the parent, and vice versa.

type Option

type Option func(cfg *Config)

Option configures the logp package behavior.

func AsJSON

func AsJSON() Option

AsJSON specifies to log the output as JSON.

func ToDiscardOutput

func ToDiscardOutput() Option
