The following DNS data metrics are collected and visualized by the BlueCat Health Monitoring service.

Queries by Type: The number of queries received by the DNS/DHCP Server, delineated by type and measured in queries per reporting interval (frequency).
Data Type Definition
A Address record
AAAA IPv6 address record
TYPE65 HTTPS binding
IXFR Incremental zone transfer
NS Name server record
PTR Reverse DNS record
SOA Start of authority record
SRV Service locator
TXT Text record
DS Delegation signer
DNSKEY DNSSEC key record
ANY All cached records
RRSIG DNSSEC signature
NAPTR Naming authority pointer
AXFR Authoritative zone transfer
MX Mail exchange record
Dynamic DNS Updates: Statistics related to Dynamic DNS Updates (requests, responses, completion statuses) over the reporting interval (frequency).
Data Type Definition
UpdateRej This indicates the number of rejected dynamic update requests.
UpdateReqFwd This indicates the number of forwarded update requests.
UpdateRespFwd This indicates the number of forwarded update responses.
UpdateDone This indicates the number of completed dynamic updates.
UpdateFail This indicates the number of failed dynamic updates.
UpdateBadPrereq This indicates the number of dynamic updates rejected due to a prerequisite failure.
Nameserver Statistics: Statistics related to nameservers (requests, responses, resolutions) over the reporting interval (frequency).
Data Type Definition
Requestv4 This indicates the number of IPv4 requests received. Note: this also counts non-query requests.
ReqEdns0 This indicates the number of requests received with EDNS(0).
RPZRewrites This indicates the number of response policy zone rewrites.
ReqBadEDNSVer This indicates the number of requests received with an unsupported EDNS version.
ReqTCP This indicates the number of TCP requests received.
AuthQryRej This indicates the number of rejected authoritative (non-recursive) queries.
RecQryRej This indicates the number of rejected recursive queries.
Response This indicates the number of responses sent.
RespTruncated This indicates the number of truncated responses sent.
RespEDNS0 This indicates the number of responses sent with EDNS(0).
QrySuccess This indicates the number of queries that resulted in a successful answer, meaning queries which return a NOERROR response with at least one answer RR. This corresponds to the success counter of previous versions of BIND 9.
QryAuthAns This indicates the number of queries that resulted in an authoritative answer.
QryNoauthAns This indicates the number of queries that resulted in a non-authoritative answer.
QryReferral This indicates the number of queries that resulted in a referral answer. This corresponds to the referral counter of previous versions of BIND 9.
QryNxrrset This indicates the number of queries that resulted in NOERROR responses with no data. This corresponds to the nxrrset counter of previous versions of BIND 9.
QrySERVFAIL This indicates the number of queries that resulted in SERVFAIL.
QryFORMERR This indicates the number of queries that resulted in FORMERR.
QryNXDOMAIN This indicates the number of queries that resulted in NXDOMAIN. This corresponds to the nxdomain counter of previous versions of BIND 9.
QryRecursion This indicates the number of queries that caused the server to perform recursion in order to find the final answer. This corresponds to the recursion counter of previous versions of BIND 9.
QryDuplicate This indicates the number of queries which the server attempted to recurse but for which it discovered an existing query with the same IP address, port, query ID, name, type, and class already being processed. This corresponds to the duplicate counter of previous versions of BIND 9.
QryDropped This indicates the number of recursive queries for which the server discovered an excessive number of existing recursive queries for the same name, type, and class, and which were subsequently dropped. This is the number of dropped queries due to the reason explained with the clients-per-query and max-clients-per-query options (see the description about clients-per-query in the BIND 9 Administrator Reference Manual.) This corresponds to the dropped counter of previous versions of BIND 9.
RateDropped This indicates the number of responses dropped due to rate limits.
Zone Maintenance: Statistics related to zone transfers (notifies, requests, completion statuses) over the reporting interval (frequency).
Data Type Definition
NotifyOutv4 This indicates the number of IPv4 notifies sent.
NotifyOutv6 This indicates the number of IPv6 notifies sent.
NotifyInv4 This indicates the number of IPv4 notifies received.
NotifyInv6 This indicates the number of IPv6 notifies received.
AXFRReqv4 This indicates the number of requested IPv4 AXFRs
AXFRReqv6 This indicates the number of requested IPv6 AXFRs.
IXFRReqv4 This indicates the number of requested IPv4 IXFRs.
IXFRReqv6 This indicates the number of requested IPv6 IXFRs.
XfrSuccess This indicates the number of successful zone transfer requests.
XfrFail This indicates the number of failed zone transfer requests.

DNS Operations: The number of DNS QUERY, DNS UPDATE, and DNS NOTIFY operations processed, measured in operations per reporting interval (frequency).

Active Connections: The number of active TCP/UDP IPv4/IPv6 connections registered per reporting interval (frequency).
