Server Monitoring - how many documents are in data cache?

Couchbase Server

How can I check the number of documents loaded into the data cache - either / or on the bucket, node or cluster level?

Thank you,

Thank you, I also get ep_bg_fetched:0, even though I browsed though view results, etc. Is this a CLI interface issue or I am misinterpreting the this value?
