Properly handle error formatting

[sohlich]

This could be obvious but please share a code snipet how you log the errors? Or repo where you experiencing this.

Configuration

	baseLogger := &logrus.Logger{
		Out:       os.Stderr,
		Hooks:     make(logrus.LevelHooks),
		Level:     logrus.DebugLevel,
		Formatter: &logrus.TextFormatter{},
	}

	logger = baseLogger.WithField("application", "encoder")

	services, _, err := consul.Catalog().Service("elasticsearch", "", &consulapi.QueryOptions{})
	if err != nil {
		logger.WithError(err).Fatal("Failed to retrieve elasticsearch")
	}

	if len(services) == 0 {
		logger.Warn("Elasticsearch not available in consul for logging")
		return
	}

	var addresses []string
	for _, service := range services {
		addresses = append(addresses, fmt.Sprintf("http://%s:%d", service.ServiceAddress, service.ServicePort))
	}

	client, err := elastic.NewClient(elastic.SetURL(addresses...))
	if err != nil {
		logger.WithError(err).Fatal("Failed to construct elasticsearch client")
	}

	hook, err := elogrus.NewElasticHook(client, getHostname(), logrus.DebugLevel, "logs")
	if err != nil {
		logger.WithError(err).Fatal("Failed to create elasticsearch hook for logger")
	}

	baseLogger.Hooks.Add(hook)

Catching a random error

err := errors.New("hello world")
err2 := errors.Wra(err, "Wrapping previous error")

logger.WithError(err2).Error("Failed to handle invalid api response")

I've stringified the error field:

{
"_index": "errorlog",
"_type": "log",
"_id": "AVuZIRPrwfM22V5jPxNV",
"_score": null,
"_source": {
"Host": "localhost",
"@timestamp": "2017-04-23T04:45:33.544389772Z",
"Message": "Failed to handle invalid api response",
"Data": {
"error": "This is error"
},
"Level": "ERROR"
},
"fields": {
"@timestamp": [
1492922733544
]
},
"sort": [
1492922733544
]
}
