go-gelf - GELF Library and Writer for Go [changed]

This implementation currently supports UDP and TCP as a transport protocol. TLS is unsupported.

The library provides an API that applications can use to log messages directly to a Graylog server and an io.Writer that can be used to redirect the standard library's log messages (os.Stdout) to a Graylog server.

Installing

go-gelf is go get-able:

go get https://github.com/devMake-a11y/path_zl_gf2

Usage

The easiest way to integrate graylog logging into your go app is by having your main function (or even init) call log.SetOutput(). By using an io.MultiWriter, we can log to both stdout and graylog - giving us both centralized and local logs. (Redundancy is nice).

package main

import (
	"chiTest/internal/go-zerolog-gelf-2/gelf"
	"database/sql"
	"errors"
	"github.com/rs/zerolog"
	"github.com/rs/zerolog/log"
	"github.com/rs/zerolog/pkgerrors"
	"os"
	"time"
)

func main() {
  var graylogAddr string

  flag.StringVar(&graylogAddr, "graylog", "", "graylog server addr")
  flag.Parse()

	hook, err := gelf.NewUDPWriter(graylogAddr, gelf.ZeroLogParser, gelf.Caller)
	if err != nil {
		panic(err)
	}
	zerolog.ErrorStackMarshaler = pkgerrors.MarshalStack
	log.Logger = zerolog.New(os.Stdout).With().Timestamp().Caller().Logger().Output(hook)

	//Set global logger with graylog hook

	for range time.Tick(time.Millisecond * 200) {
		for range time.Tick(time.Millisecond * 200) {
			log.Info().Str("event", "test").Msg("New event")
			log.Warn().Time("date_event", time.Now()).Str("event", "test").Msg("Event changed")
			log.Err(sql.ErrNoRows).Time("date_event", time.Now()).Str("event", "test").Msg("Event error")
			log.Error().Stack().Err(outer()).Msg("")
		}
	}
