Application.yml:
server:
port: 9999
spring:
application:
name: spring-boot-admin
security:
user:
name: admin
password: password
boot:
admin:
discovery:
ignored-services: spring-boot-admin
eureka:
enabled: true
instance:
preferIpAddress: true
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/
With this configuration, i can acess the SBA, like the images bellow:
Login page
Application page (looks normally)
Error in service health details and don't show the menu for graphics
How it should looks like
Does anyone know why that happens or/and what can i do?

Answer 1

I had a similar issue with spring boot admin. I could not visualize info of registered client in eureka.
I had to add this configuration in my application.yml of my microservices.
management:
endpoints:
web:
exposure:
include: "*"
According to documentation:
As with Spring Boot 2 most of the endpoints aren’t exposed via http by default, we expose all of them. For production you should carefully choose which endpoints to expose.
Are you including above configuraton in clients? Can you share you spring boot client application.yml ?
You can check my sample here. the monitor-app is implementing Springboot Admin. I hope it helps you
