The number of times the server started a lookup with the next query.

DiscardedDuplicateQueries

Data type: uint32

Access type: Read-only

FailureReachPreviousResponse

Data type: uint32

Access type: Read-only

The number of times the server received failure while performing recursive lookup on queries, because the query recursed back to the domain from which a name server had already responded.
