How to aggregate multiple Host from diffrent account in Elastic stack to support mutitenecey

How to aggregate multiple Host from different account in Elastic stack to support mutitenecey!
We have thousand of thousand system(linux and Windows) from multiple account for monitoring using Beat.
How we can aggregate the multiple server from single account under Elastic stack ?

It's not immediately clear what you mean by this, can you please elaborate?

Actually, I will close this in favour of Is it mutitenecy supported by ELK?. Please don't create multiple topics on the same question :slight_smile:
