Hi

I have a nls 2-node cluster with 32GB RAM for each nls. As I checked, Under Admin -->Instance status, used mem has been more than 32 GB. Please see the attached screenshot.

Can you please help me to understand it?

Thank you

My memory may be failing me, but I'm *pretty sure* those stats are cluster-level, evaluated by hitting the _cluster/stats endpoint of the ElasticSearch API and evaluating the os section of the returned result. The measurements represent the combined resources of all nodes in the cluster.

There is also a _node/stats endpoint which does roughly the same thing, but for an individual node.

Awesome memory, @mcapa!

It's making a call to _cluster/stats?human and then extracting from nodes > os > memory > total.
