Number of non-transaction query operations that use default write
2+
concerns. The metrics track usage of the :dbcommand:`cluster wide write
3+
concern <setDefaultRWConcern>` (the global default write concern) and
4+
the implicit-default write concern.

6+
The sum of the values in ``opWriteConcernCounters.noneInfo`` should
7+
equal the value of ``opWriteConcernCounters.none``.
