How to get actual memory (excluding cache/buffer memory) consumed by opensearch process

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser): 2.11.0

Describe the issue:
Mem used in Bytes from Stats API is showing higher than Kubectl top pods response - OpenSearch - OpenSearch

It is evident from the discussion above that “used_in_bytes” includes buffered/cached memory; nevertheless, whatever stat API allows us to obtain the real memory used by the opensearch process (apart from cache/buffer memory), which ought to be equal to the output of kubectl top pods?

Would you kindly let us know which stat API we should use to verify the actual memory?
