Monitoring or Distributed 2 Elastic stack to 1 elastic

I have two branch offices that use elaticsearch. but I want both of them to be monitored centrally at the head office. Can it? and how? thank you

Monitoring in a production environment | Elasticsearch Guide [8.1] | Elastic, but send both clusters to the same endpoint.

You do need a Gold or above license for this to work - Subscriptions | Elastic Stack Products & Support | Elastic

okay, thanks

Alternatively you could send the metrics to a (smallish) cluster on Elastic Cloud, as it would come with a Platinum license and then cover you.
