What is dnsServCounterNonAuthDatas?
This counter measures the total number of DNS queries that were answered with cached data (non-authoritative responses) rather than freshly retrieved from authoritative nameservers. DNS operators use this metric to understand cache hit rates and verify that their caching policies are working as intended, which affects both query response times and upstream query load.
