* coredns_dns_request_count_total
* coredns_dns_request_duration_seconds
* coredns_dns_request_size_bytes
* coredns_dns_request_do_count_total
* coredns_dns_response_size_bytes

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 an extra label `proto` which
holds the transport of the response ("udp" or "tcp"). The `response_rcode_count_total` has an extra
label `rcode` which holds the rcode of the response.
`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)).
The `response_rcode_count_total` has an extra label `rcode` which holds the rcode of the response.
If monitoring is enabled queries that do not enter the middleware chain are exported under the fake
domain "dropped" (without a closing dot).
