      Presently the commands db.stats() and db.collection.stats() both accept scale parameters. The WiredTiger stats reported by db.collection.stats() are hard coded by description and value to denote units in bytes only.

      This request is to expose some WiredTiger statistics by mapping them directly into a db.collection.stats() method to support the scale option.

      Notably the WiredTiger "block-manager" stats of interest (but not limited to):

      • db.collection.stats( { scale: 1 }).storageSize maps to "wiredTiger"."block-manager"."file size in bytes"
      • db.collection.stats( { scale: 1 }).freeListSize maps to "wiredTiger"."block-manager"."file bytes available for reuse"
