Package statsd provides a Go dogstatsd client. Dogstatsd extends the popular statsd,
adding tags and histograms and pushing upstream to Datadog.

Refer to http://docs.datadoghq.com/guides/dogstatsd/ for information about DogStatsD.

Example Usage:

    // Create the client
    c, err := statsd.New("127.0.0.1:8125")
    if err != nil {
        log.Fatal(err)
    }
    // Prefix every metric with the app name
    c.Namespace = "flubber."
    // Send the EC2 availability zone as a tag with every metric
    c.Tags = append(c.Tags, "us-east-1a")
    er
    
func (sc ServiceCheck) Encode(tags ...string) (string, error) {
	err := sc.Check()
	if err != nil {
		return "", err
	}
	message := sc.escapedMessage()

	var buffer bytes.Buffer
	buffer.WriteString("_sc|")
	buffer.WriteString(sc.Name)
	buffer.WriteRune('|')
	buffer.WriteString(strconv.FormatInt(int64(sc.Status), 10))

	if !sc.Timestamp.IsZero() {
		buffer.WriteString("|d:")
		buffer.WriteString(strconv.FormatInt(int64(sc.Timestamp.Unix()), 10))
	}

	if len(sc.Hostname) != 0 {
		buffer.WriteString("|h:")
		buffer.WriteString(sc.Hostname)
	}

	writeTagString(&buffer, tags, sc.Tags)

	if len(message) != 0 {
		buffer.WriteString("|m:")
		buffer.WriteString(message)
	}

	return buffer.String(), nil
}
