    Description

      keysInserted and keysDeleted metrics have been added to mongoD diagnostics under SERVER-23271. These metrics will be available via slow diagnostic logging and in the profiler.

      Definitions:

      • keysInserted: The number of index keys inserted for a given write operation.
      • keysDeleted: The number of index keys deleted for a given write operation.

      Note: We define "operation" here to be a single user operation. A 'find' followed by a 'getMore' on the returned cursor would count as separate operations.

      Operations that can report keysInserted:

      1. insert
      2. update
      3. findAndModify

      Operations that can report keysDeleted:

      1. delete
      2. update
      3. findAndModify
