Description
In my application, I've configured the following ignored services;
spring.boot.admin:
discovery.ignored-services: ["ZOOKEEPERS SERVICE REGISTRY"]because I don't want Spring Boot Admin to monitor them (that's the Eureka service registry).
But, for some reason, such filter is ignored and SBA tries to fetch the status of that app as well (which fails):
