Spring Cloud Discovery

The Spring Boot Admin Server is capable of using Spring Clouds DiscoveryClient to discover applications. The advantage is that the clients don’t have to include the spring-boot-admin-starter-client. You just have to add a DiscoveryClient to your admin server - everything else is done by AutoConfiguration. The setup is explained above.

ServiceInstanceConverter

The informations from the discovered services are converted by the ServiceInstanceConverter. Spring Boot Admin ships with a default and Eureka converter implementation. The correct one is selected by AutoConfiguration. You can use your own conversion by implementing the interface and adding the bean to your application context.

If you want to customize the default conversion of services you can either add health.path, management.port and/or mangament.context-path entries to the services metadata. This allows you to set the health or management path per application. In case you want to configure this for all of your discovered services, you can use the spring.boot.admin.discovery.converter.* properties for your Spring Boot Admin Server configuration. The services' metadata takes precedence over the server configuration. For the health-url the EurekaServiceInstanceConverter uses the healthCheckUrl registered in Eureka, which can be set for your client via eureka.instance.healthCheckUrl.
