 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
