We have CCR enabled in Elasticsearc and there are few indices getting replicated. Is there a way to setup monitoring alert using watcher script by querying \_ccr/stats and trigger an alert if data is not getting replicated ?

I think this is possible, but we don't have this kind of watcher (in particular) out of the box. Should be pretty straight forward to implement by querying `_ccr/stats` and matching replicas. Here is a helpful guide to get started: [https://www.elastic.co/guide/en/elasticsearch/reference/current/how-watcher-works.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/how-watcher-works.html)

I'm trying to write a query to extract "time\_since\_last\_read\_millis" from \_ccr/stats using GET.  
Is there a way to extract only fields from \_ccr/stats instead of getting field from `hostname:port/_ccr/stats`
