Types

type Logger

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

Logger wraps a Logger from package github.com/go-kit/log to provide a more convenient way to log with a particular level. Note that Logger still implements the Logger interface from github.com/go-kit/log.

func DefaultJSONLogger

func DefaultJSONLogger(options ...Option) *Logger

Default logger that encodes log events as a single json object and writes them to stdout.

There are four different log levels: error/warn/info/debug (in descending order of severity). An option can be passed to filter out log messages below a certain level. E.g. if AllowInfo is passed, only log messages with level info/warn/error or without a level will be logged. By default only log messages with or above level info are logged.

func (Logger) Debug

func (l Logger) Debug() Logger

Returns a logger that logs with level Debug.

func (Logger) Error

func (l Logger) Error() Logger

Returns a logger that logs with level Error.

func (Logger) Info

func (l Logger) Info() Logger

Returns a logger that logs with level Info.

func (Logger) Log

func (Logger) Warn

func (l Logger) Warn() Logger

func (Logger) With
