I need a way to monitor a search index over time - for example knowing how many documents are indexed over time grouped by some field/attribute (e.g. how many products of type X, Y and Z are in our index and how has that changed over time)

I can think of ways to do this externally to ES - e.g. query the search engine periodically and store my findings somewhere. Is there another more baked in solution or plugins I should be looking into?

I believe that watcher which is included in X-Pack (commercial) can do that.
