Elastic monitoring cluster

Hi, starting to look into setting a dedicated monitoring cluster to capture all monitoring data from elasticsearch nodes. We are at v7.11 and I see the .monitoring indices size is about 3.5GB/day/cluster. Trying to seek some recommendations around how many node cluster would typically suffice to meet the monitoing needs - single node vs multiple node (2 or 3).

Our intent is to setup two such monitoring clusters -
Prod : send monitoring data from three separate ES clusters
Non-Prod : send monitoring data from two separate ES clusters


Start with 1 and then scale as needed and you should be fine.
Please note though, that multi-cluster monitoring is a Gold and above license level.

This sort of use is ideal for Elastic Cloud, as you can start super small and easily scale and not have the admin overhead.
