How to check which node is serving request

I created couchbase 4.0 conatiner on docker locally on my windows 10 machine. And I performed get and set operation on couchbase using a demo Golang app. I checked logs and other places but I was not able to find any info which points me to node in cluster which is handling request from client.

I also tried by creating 2 node clusters on aws and did db operation. I made one node down and make some request from client and made that node up and again made some request. But in logs I was not able to get which node is handling request from client. I searched by ip address of node.

Is there a way to find out which node is serving request in logs or any other way, so that I can check if a node is down and after coming back up it is serving request.
