Spring Cloud Load Balancer - 有没有办法查看选择了哪个实例？
我们正在从 Ribbon 切换到 Spring Cloud Load Balancer，到目前为止一切似乎都正常。不过，我希望能够查看每个请求选择了哪个实例来验证行为。
是否有调试标志或其他方式来查看 SCLB 在每个请求上选择哪个实例？
We're switching from Ribbon to Spring Cloud Load Balancer, and thus far things seem to work. However I want to be able to see which instance is chosen on each request to verify the behavior.
Is there a debug flag or some other way to see which instance SCLB is choosing on each request?

选定的服务实例将被记录在客户端的各个位置进行调试，例如在
ReactorLoadBalancerExchangeFilterFunction，在RetryLoadBalancerInterceptor，在RetryableLoadBalancerExchangeFilterFunction等。此外，对于WebClient支持的负载平衡您可以启用设置实例ID 作为 cookie。您还可以启用 Micrometer support，它将注册各种有用的指标，包括实例 ID。此外，您可以使用LoadBalancerLifecycle回调。The selected service instances are logged for debug in various places on the client side, for example in
ReactorLoadBalancerExchangeFilterFunction, inRetryLoadBalancerInterceptor, inRetryableLoadBalancerExchangeFilterFunction, etc. Also,forWebClient-backed load-balancing you can enable setting instance Id as a cookie. You can also enable Micrometer support, which will register various useful metrics, including instance ids. Additionally, you can implement your own logging mechanism using theLoadBalancerLifecyclecallbacks.
