Get detailed breakdown of memory consumption for Elastic Search

Question

For ElasticSearch (provisioned through AppSearch), is there a way to get a detailed breakdown of consumed memory within the jvm or elastic process?

We are currently suffering from a lot of circuit breaks but there is no obvious cache or index that seems to be consuming a large amount of memory.

The request_cache, query_cache, and fielddata index are all relatively small.

When we use the _cache/clear endpoint, we get a brief respite, but its not permanent

Edit: Example of one of our circuit breaker errors

        ]
    }
}
