Example 26 with CircuitBreaker
use of io.github.resilience4j.circuitbreaker.CircuitBreaker in project resilience4j by resilience4j.
the class CircuitBreakerEventsEndpoint method getEventsStreamFilteredByCircuitBreakerNameAndEventType.
@RequestMapping(value = "stream/events/{circuitBreakerName}/{eventType}", produces = MEDIA_TYPE_TEXT_EVENT_STREAM)
public SseEmitter getEventsStreamFilteredByCircuitBreakerNameAndEventType(@PathVariable("circuitBreakerName") String circuitBreakerName, @PathVariable("eventType") String eventType) {
CircuitBreaker circuitBreaker = circuitBreakerRegistry.getAllCircuitBreakers().find(cb -> cb.getName().equals(circuitBreakerName)).getOrElseThrow(() -> new IllegalArgumentException(String.format("circuit breaker with name %s not found", circuitBreakerName)));
Flux<CircuitBreakerEvent> eventStream = toFlux(circuitBreaker.getEventPublisher()).filter(event -> event.getEventType() == CircuitBreakerEvent.Type.valueOf(eventType.toUpperCase()));
return CircuitBreakerEventEmitter.createSseEmitter(eventStream);
