	"time"
)

type AlertMsg struct {
	Receiver          string
	Status            string
	GroupLabels       map[string]string
	CommonLabels      map[string]string
	CommonAnnotations map[string]string
	ExternalURL       string
	Alerts            []Alert
}

type Alert struct {
	Status       string
	Labels       map[string]string
	Annotations  map[string]string
	StartsAt     time.Time

	GeneratorURL string
	Fingerprint  string
}

func main() {
	http.HandleFunc("/alerts", alertHandler)
	log.Fatal(http.ListenAndServe("0.0.0.0:5001", nil))
}

func alertHandler(w http.ResponseWriter, r *http.Request) {
	dec := json.NewDecoder(r.Body)
	defer r.Body.Close()

	var m AlertMsg
	if err := dec.Decode(&m); err != nil {
		log.Printf("decoding alert message error: %v", err)
		return
	}
	content, _ := json.MarshalIndent(m, "", "    ")
	fmt.Println(string(content))
}
