We do have monitoring enabled. I am running version 6.6.2. I do fully intend to upgrade to the latest version but so far it is not an easy matter to reindex all the docs from a named doc type to _doc.
Previously, the depreciation log gave me a warning but it seems that the latest depreciation path no longer gives that. Our indices only have a single doc type so it doesn’t matter what they are called. Is that why?
