What is dnsServCounterNonAuthNoDatas?
This counter tracks the number of DNS queries answered non-authoritatively (from cache or forwarded data) that returned no matching records, also called negative responses or empty answers. DNS servers maintain this metric to understand query patterns and identify zones where no data is available. Operators analyze this to optimize caching behavior and detect potential configuration issues.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.32.1.1.2.6 snmpwalk -v2c -c public <target> DNS-SERVER-MIB::dnsServCounterNonAuthNoDatas
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.32.1.1.2.6.1 snmpget -v2c -c public <target> DNS-SERVER-MIB::dnsServCounterNonAuthNoDatas.1
Start monitoring DNS server host software, e.g. BIND (vendor-neutral, IETF/IANA standard) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the DNS-SERVER-MIB::dnsServCounterNonAuthNoDatas OID value, configure state conditions and alerts, and monitor any DNS server host software, e.g. BIND (vendor-neutral, IETF/IANA standard) from a single console.
