Resilience4j: CircuitBreakers events in actuactor end-point doesn't works after updating in runtime

[JuanMorenoS]

Resilience4j version: 1.5.0
Java version: 11

Hi!

I want to update the circuit-breakers configuration at runtime, I have a schedule that consumes the DB and I update the configuration every 5 minutes (similar to this issue https://github.com/resilience4j/resilience4j/issues/850). To update the CBs I use the replace function in the CircuitbreakerRegistry, but after the first update, I stop seeing the CBs events at the actuator end point.

Hi,

do you use Spring Boot?
Did you set up resilience4j-micrometer yourself?
Could you please show me how you did it.

Hi @RobWin

Yes, I use the last version of spring-boot 2.3.2 and no I use the R4J default config

Shure!

That's how I update circuit breakers:

CircuitBreaker oldCircuitBreaker = circuitBreakerRegistry.circuitBreaker(name);
CircuitBreaker updatedCircuitBreaker = getLastVersion(oldCircuitBreaker);
circuitBreakerRegistry.replace(name, updatedCircuitBreaker);

After replacement, the end point of the actuator shows the oldest CB object

I was checking, and notice that EventConsumerRegistry<CircuitBreakerEvent> in CircuitBreakerEventsEndpoint is never updated.

Hi,
yes you are right. That's a bug / missing feature.

As an alternative you could have a look at Spring Cloud Config.
