Elasticsearch document size

Elastic Stack Elasticsearch
1

Hi,

I know there has been multiple threads on finding size of a document in Elasticsearch. I have not found a conclusive answer for ELK 6.x.

For my benchmarking purposes, I would like to know the average size of documents stored in an index in Elasticsearch. I am using ELK 6.3. Previously, the size parameter was available but i do not see it in the latest versions.

Is there a way to find the average (or exact) size of document in an index in Elasticsearch?

Thanks,
Raji

If you want exact then see https://www.elastic.co/guide/en/elasticsearch/plugins/current/mapper-size.html

If you are ok with an average then just get the byte size of the index and then divide that by the number of documents.
