Circuit Breaker is not showing in component section in spring boot - spring-boot

Question

I configured actuator and reselience4j in application.yml file
Here is my application.yml file
management:
endpoint:
health:
show-details: always
circuitbreakers:
enabled: true
web:
endpoints:
web:
exposure:
include: health
resilience4j:
circuitbreaker:
instances:
ratingHotelBreaker:
register-health-indicator: true
event-consumer-buffer-size: 10
failure-rate-threshold: 50
minimum-number-of-calls: 5
automatic-transition-from-open-to-half-open-enabled: true
wait-duration-in-open-state: 6s
permitted-number-of-calls-in-half-open-state: 3
sliding-window-size: 10
sliding-window-type: count_based
This is my pom.xml file.

Still I am not getting circuit breaker configuration after hitting actuator/health URL.
Here is Image what I am getting
In this image circuit breaker section is not there
What is missing in configuration ?

Answer 1

This is the ideal configuration to enable health metric endpoint for the circuit breaker. Refere here for more at Health endpoint seciton.
application.yml
management.health.circuitbreakers.enabled: true
management.health.ratelimiters.enabled: true
resilience4j.circuitbreaker:
configs:
default:
registerHealthIndicator: true

Answer 2

The application.yml management & resilience4j hierarchies are wrong. The following works:
management:
health:
circuitbreakers:
enabled: true
endpoint:
health:
show-details: always
endpoints:
web:
exposure:
include: health
resilience4j:
circuitbreaker:
configs:
default:
registerHealthIndicator: true
instances:
ratingHotelBreaker:
register-health-indicator: true
event-consumer-buffer-size: 10
failure-rate-threshold: 50
minimum-number-of-calls: 5
automatic-transition-from-open-to-half-open-enabled: true
wait-duration-in-open-state: 6s
permitted-number-of-calls-in-half-open-state: 3
sliding-window-size: 10
sliding-window-type: COUNT_BASED
/actuator/health returns as follows for your pom file:
