  // This here will appear as a label, one can also use

  // fiberprometheus.NewWith(servicename, namespace, subsystem )

  // or

  // labels := map[string]string{"custom_label1":"custom_value1", "custom_label2":"custom_value2"}

  // fiberprometheus.NewWithLabels(labels, namespace, subsystem )

    return c.SendString("Hello World")

  })

  app.Get("/ping", func(c *fiber.Ctx) error {
