Index last update date

Elastic Stack Elasticsearch

Hi,
I'm looking for a way to get last index modification approximate date. Is there any way to get from ES information about last date when index files have been modified? I don't need precise date when the last document has been inserted.

When I look directly at OS level I can get Lucene segment files modification date. This would satisfy me but I don't know how I can get this information from ES level through ES API. I'd appreciate any suggestions.

I don't think we expose this via the API, at least I can't find anything.
It'd be a good idea for a feature request though!

How can I open a feature request? Github issue?

That's correct.
