Golang New Examples

Example #1

File: syslog_test.go Project: visenze/logrus

func TestLocalhostAddAndPrint(t *testing.T) {
	log := logrus.New()
	hook, err := NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")

	if err != nil {
		t.Errorf("Unable to connect to local syslog.")
	}

	log.Hooks.Add(hook)

	for _, level := range hook.Levels() {
		if len(log.Hooks[level]) != 1 {
			t.Errorf("SyslogHook was not added. The length of log.Hooks[%v]: %v", level, len(log.Hooks[level]))
		}
	}

	log.Info("Congratulations!")
}

Example #2

File: hook.go Project: visenze/logrus

package main

import (
	"github.com/visenze/logrus"
	"gopkg.in/gemnasium/logrus-airbrake-hook.v2"
)

var log = logrus.New()

func init() {
	log.Formatter = new(logrus.TextFormatter) // default
	log.Hooks.Add(airbrake.NewHook(123, "xyz", "development"))
}

func main() {
	log.WithFields(logrus.Fields{
		"animal": "walrus",
		"size":   10,
	}).Info("A group of walrus emerges from the ocean")

	log.WithFields(logrus.Fields{
		"omg":    true,
		"number": 122,
	}).Warn("The group's number increased tremendously!")

	log.WithFields(logrus.Fields{
		"omg":    true,
		"number": 100,
	}).Fatal("The ice breaks!")
}

Example #3

File: sentry_test.go Project: visenze/logrus_sentry

func getTestLogger() *logrus.Logger {
	l := logrus.New()
	l.Out = ioutil.Discard
	return l
}
