Documentation

Overview

Package log contains adapter for third-party loggers

Example:

package main

import (
	"github.com/insolar/insolar/configuration"
	"github.com/insolar/insolar/log"
)

func main() {
	// global logger
	log.SetLevel("Debug")
	log.Debugln("debug log message")

	// local logger
	logger, _ := log.NewLog(configuration.Log{Level: "Warning", Adapter: "logrus"})
	logger.Warnln("warning log message")
}

GlobalLogger creates global logger with correct skipCallNumber TODO: make it private again

func NewLog

func NewLog(cfg configuration.Log) (core.Logger, error)

NewLog creates logger instance with particular configuration

func Panic

func Panic(args ...interface{})

Panic logs a message at level Panic to the global logger.

func Panicf

func Panicf(format string, args ...interface{})

Panicf logs a message at level Panic to the global logger.

func Panicln

func Panicln(args ...interface{})

Panicln logs a message at level Panic to the global logger.

func SetLevel

func SetLevel(level string) error

SetLevel lets log level for global logger

func SetOutput

func SetOutput(w io.Writer)

SetOutput sets the output destination for the logger.

func Warn

func Warn(args ...interface{})

func WithSkipDelta

func WithSkipDelta(cl core.Logger, delta int) core.Logger

WithSkipDelta changes current skip stack frames value for underlying logrus adapter on delta value. More about skip value is here https://golang.org/pkg/runtime/#Caller.

This is useful than logger methods called not from place they should report, like helper functions.
