        I have 4 Microservices before I start adding Edge Servers/Config Servers/etc
        
        how do I monitor them?
        
        Spring Boot gives me simple monitoring if I add a pom.xml dependency
        
        
        
                Spring Boot include a tool to measure metrics, the Actuator
                
                you add this dependency to the project pom.xml:
                
                <dependency>
                        <groupId>org.springframework.boot</groupId>
                        <artifactId>spring-boot-starter-actuator</artifactId>
                </dependency>
                
                
                By default there are a couple endpoints exposed by the actuator
                
                you can see the list of endpoints via this URL:
                
                http://localhost:9091/actuator  
                
                the health endpoint is enabled by default
                http://localhost:9091/actuator/health
                
                you can request more details via the application.properties file
                management.endpoint.health.show-details=always
                
        
                
                
                there are a number of other endpoints that can be enabled,
                see: https://docs.spring.io/spring-boot/reference/actuator/endpoints.html
                
                you can manage the  actuator endpoints in the application.properties file
                like this:
        
                management.endpoint.beans.enabled=true                   <- turn on the endpoint
                management.endpoints.web.exposure.include=health,beans   <- add it to the exposed endpoints
