Types ¶

type Levels ¶

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

Levels provides a leveled logging wrapper around a logger. It has five levels: debug, info, warning (warn), error, and critical (crit). If you want a different set of levels, you can create your own levels type very easily, and you can elide the configuration.

package main

import (
	"os"

	levels "github.com/go-kit/kit/log/deprecated_levels"
	"github.com/go-kit/log"
)

func main() {
	logger := levels.New(log.NewLogfmtLogger(os.Stdout))
	logger.Debug().Log("msg", "hello")
	logger.With("context", "foo").Warn().Log("err", "error")

}

level=debug msg=hello
level=warn context=foo err=error

func New ¶

func New(logger log.Logger, options ...Option) Levels

New creates a new leveled logger, wrapping the passed logger.

func (Levels) Crit ¶

func (l Levels) Crit() log.Logger

Crit returns a critical level logger.

func (Levels) Debug ¶

func (l Levels) Debug() log.Logger

Debug returns a debug level logger.

func (Levels) Error ¶

func (l Levels) Error() log.Logger

Error returns an error level logger.

func (Levels) Info ¶

func (l Levels) Info() log.Logger

Info returns an info level logger.

func (Levels) Warn ¶

func (l Levels) Warn() log.Logger

Warn returns a warning level logger.

func (Levels) With ¶

func (l Levels) With(keyvals ...interface{}) Levels

With returns a new leveled logger that includes keyvals in all log events.

type Option ¶

type Option func(*Levels)

Option sets a parameter for leveled loggers.

func CritValue ¶

func CritValue(value string) Option

CritValue sets the value for the field used to indicate the critical log level. By default, the value is "crit".

func DebugValue ¶

func DebugValue(value string) Option

DebugValue sets the value for the field used to indicate the debug log level. By default, the value is "debug".

func ErrorValue ¶

func ErrorValue(value string) Option
