FAIL answers is the number of responses indicating either that the name does not exist or that
there is no data of the requested type for this name.
FORMERR answers is the number of malformed response packets from other name servers. A
message is sent to the syslog daemon listing the sender of the malformed response packet.
system queries are queries generated by the name server. These usually occur when the
name server detects another name server listed for a domain for which there is no address data.
The system query is an attempt to find the address data for that name server. System queries are
also used to keep up-to-date information about the name servers for the root domain.
prime cache calls are calls to update the information about the name servers for the root
domain.
check_ns calls are calls to check the state of the information about the name servers for the
root domain.
bad responses dropped are responses from remote name servers that are dropped. These
occur most often when the remote name server responds with SERVFAIL, indicating a problem
with the server’s domain data.
martian responses are responses from unexpected addresses. The name server keeps track
of how long it takes for a remote name server to respond. If the remote name server is a
multi-homed host, a query to one of the addresses may result in a response from another of its
addresses. If the local server does not know about this other address, the response is counted as
a martian response.
unknown query types are queries for data types unknown to this server.
A queries are queries for the host address for a domain name. The gethostbyname library
routine generates these address queries.
CNAME queries are queries for the canonical name for a domain name. Some versions of
sendmail query for CNAME records during name canonicalization from $[$] tokens in
/var/adm/sendmail/sendmail.cf.
SOA queries are queries for the start of authority records. These queries are most often made
by slave servers over a stream connection to check if their domain data is current.
PTR queries are queries for the domain name for a host address. The gethostbyaddr library
routine generates these queries.
MX queries are mail exchanger queries made by sendmail during the delivery of electronic
mail.
AXFR queries are the number of zone transfers done by slave servers. A slave server first
makes an SOA query and follows that with an AXFR query if new domain data should be
transferred.
ANY queries are queries for any data associated with the domain name. Some versions of
sendmail make queries for ANY data during name canonicalization from $[$] tokens in
/var/adm/sendmail/sendmail.cf.
