@@ -9,13 +9,17 @@ The following metrics are exported:
* coredns_dns_request_duration_seconds
* coredns_dns_request_size_bytes
* coredns_dns_request_do_count_total
* coredns_dns_request_type_count_total
* coredns_dns_response_size_bytes
* coredns_dns_response_rcode_count_total
Each counter has a label `zone` which is the zonename used for the request/response. and a label
`qtype` which old the query type. The `dns_request_count_total` has extra labels: `proto` which
holds the transport of the response ("udp" or "tcp") and the address family of the transport (1
= IP (IP version 4), 2 = IP6 (IP version 6)).
= IP (IP version 4), 2 = IP6 (IP version 6)). And `type_count_total` hold a per RR type counter, it
holds the most common ones (A, AAAA, MX, SOA, CNAME, PTR, TXT, NS, SRV, DS, DNSKEY, RRSIG, NSEC,
NSEC3) and "other" which lumps together all other types.
The `response_rcode_count_total` has an extra label `rcode` which holds the rcode of the response.
The `*_size_bytes` counters also hold the protocol in the `proto` label ("udp" or "tcp").
