      MongoS starts off by issuing a query of batch size 0. Thus, cursors by MongoS will always call a getMore, and therefore, the server status metric which tracks how many cursors return more than one batch will have an artificially inflated value.

      The solution - we will be counting the number of cursors that call getMore on MongoS. Thus we will know when to ignore the artificially inflated value.
