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.

Example
package main

import (
	"os"

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

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

}
Output:

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