HTTP Interceptors

You can intercept and modify requests and responses made to the monitored application’s actuator endpoints by implementing the InstanceExchangeFilterFunction interface. This can be useful for auditing or adding some extra security checks.

CustomHttpInterceptor.java

@Bean
public InstanceExchangeFilterFunction auditLog() {
    return (instance, request, next) -> next.exchange(request).doOnSubscribe((s) -> {
        if (HttpMethod.DELETE.equals(request.method()) || HttpMethod.POST.equals(request.method())) {
            log.info("{} for {} on {}", request.method(), instance.getId(), request.url());
        }
    });
}
