func urlSkipper(c echo.Context) bool {
    if strings.HasPrefix(c.Path(), "/health-check") {
        return true
    }
    return false
}

func main() {
    e := echo.New()

    additionMetrics := []*prometheus.Metric{&prometheus.Metric{
        ID:   "helloCnt",
        Name: "hellos_total",
        Description: "How many times this app says hello to users.",
        Type: "summary",
    }}

    p := prometheus.NewPrometheusWithConfig(prometheus.Config{
