import(
	"github.com/Sirupsen/logrus"
	"github.com/evalphobia/go-log-wrapper/log/fluent"
	"github.com/evalphobia/go-log-wrapper/log/sentry"
)

func main(){
	// fluentd
	fluent.AddLevel(logrus.DebugLevel)
	fluent.Set(host, port)

	// Sentry
	sentry.AddLevel(logrus.WarnLevel)
	sentry.Set("https://....:[email protected]/99999")

	// AppNeta TraceView

}

Logger Instance

package main

import (
	"github.com/evalphobia/go-log-wrapper/log"
)

var logger1 = log.NewLogger()
var logger2 = log.NewLogger()


func main() {
	// global log level sets Error-level
	log.SetGlobalLogLevel(log.Error)

	// logger1 write log to file
	file, _ := os.Create(`/path/to/file`)
	logger1.SetOutput(file)
	logger1.SetLogLevel(log.Debug)

	// logger2 does not write to file, use Sentry hook
	logger2.DisableOutput()
	sentry.SetLogger(logger2, dsn)

	// global logging
	log.Packet{
		Title: "Error by global level",
	}.Error()

	// use logger1
	log.Packet{
		Logger: logger1,
		Title:  "Info by logger1",
	}.Info()

	// use logger2
	log.Packet{
		Logger: logger2,
		Title:  "logger2 does not print, only hooks",
	}.Error()
