Spring boot admin server not showing u\eureka clients registered on eureka server - spring-cloud

Question

Below is my eureka server application main class
package com.example.restaurant.server.startup;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
import de.codecentric.boot.admin.server.config.EnableAdminServer;
#EnableEurekaServer
#SpringBootApplication
#EnableAdminServer
public class RestaurantEurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(RestaurantEurekaServerApplication.class, args);
}
}
Here is the application.properties file for same
spring.application.name=RestaurantEurekaServer
eureka.client.service-url.defaultZone=http://localhost:9091/
server.port=9091
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
security.basic.enabled= false
management.security.enabled= false
eureka.instance.health-check-url=/actuator/health
eureka.instance.home-page-url=/actuator/info
spring.boot.admin.context-path=/admin
management.endpoints.web.exposure.include=*
management.endpoint.health.show-details=always
The problem is my eureka server dashboard shows the clients registered on it but when i navigate to spring boot admin,it shows 0 applications registered

Answer 1

in application.properties, the eureka.client.fetch-registry should be true. With this, SBA can fetch the registration from eureka server.

Answer 2

Okay so after working on it for couple of days i figured it out
I had not set spring.boot.admin.client.url property in client due to which client was not aware on which server admin is running.
So 2 properties that i added in client are
spring.boot.admin.client.url=http://localhost:9095
spring.boot.admin.client.name=""//client will be registered in spring boot admin with his name
Also added maven dependency for spring boot admin in each client.

Answer 3

I think your problem is:
eureka.client.service-url.defaultZone=http://localhost:9091/
needs to be:
eureka.client.service-url.defaultZone=http://localhost:${server.port}/eureka/

Answer 4

you need to set in server
eureka.client.fetch-registry=true
and
#EnableDiscoveryClient
and you dependencies below is wrong:
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-server</artifactId>
<version>2.0.1</version>
</dependency>
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-server-ui</artifactId>
<version>2.0.1</version>
</dependency>
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-starter-client</artifactId>
<version>2.0.1</version>
</dependency>
only need dependency:
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-starter-server</artifactId>
<version>2.2.0</version> # change to your case
</dependency>
