Let imagine I have multiple cache instances. Is it possible to get cache stats for all available instances?

The chapter 5 of Designing Data-Intensive Applications discuss a little about it. For that you need a couple of things:

Authentication for obvious security reasons.
Is there going to be a leader who gathers & merges all stats and return it back to the client/caller?
If not, how are the instances finding each other? For that you need a service discovery, you could argue that they can be in the same machine. Still complicated, because Nodejs doesn't have a standard way of cross program communication, you could use a library like Messenger.js, but it seems overkill.
