 * 

 * {@literal @}SpringBootApplication
 * {@literal @}EnablePrometheusEndpoint
 *  public class Application {
 *
 *    public static void main(String[] args) {
 *      SpringApplication.run(Application.class, args);
 *    }
 *  }
 * 
 * 
 * Configuration:
 * 
You can customize this endpoint at runtime using the following spring properties:
 * 

 * {@code endpoints.prometheus.id} (default: "prometheus")
 * {@code endpoints.prometheus.enabled} (default: {@code true})
 * {@code endpoints.prometheus.sensitive} (default: {@code true})
