 ## How to have metrics collected for your applications
 
 When you deploy an application with Oracle Backend for Spring Boot and Microservices CLI or Visual Code Extension, provided you included the Eureka Discovery Client and Actuator in your application, Prometheus will automatically find your application (using the service registry) and start collecting metrics. These metrics will be included in both the Spring Boot Observability dashboard and the Spring Boot Statistic dashboard automatically.
