prometheus
This module enables prometheus metrics for CoreDNS. The default location for the metrics is
localhost:9153. The metrics path is fixed to /metrics.
The following metrics are exported:
- coredns_dns_request_count_total{zone, proto, family}
- coredns_dns_request_duration_milliseconds{zone}
- coredns_dns_request_size_bytes{zone,, proto}
- coredns_dns_request_transfer_size_bytes{zone,, proto}
- coredns_dns_request_do_count_total{zone}
- coredns_dns_request_type_count_total{zone, type}
- coredns_dns_response_size_bytes{zone, proto}
- coredns_dns_response_transfer_size_bytes{zone, proto}
- coredns_dns_response_rcode_count_total{zone, rcode}
Each counter has a label zone which is the zonename used for the request/response.
Extra labels used are:
protowhich holds the transport of the response ("udp" or "tcp")- The address family (
family) of the transport (1 = IP (IP version 4), 2 = IP6 (IP version 6)). typewhich holds the query type. It holds most common types (A, AAAA, MX, SOA, CNAME, PTR, TXT, NS, SRV, DS, DNSKEY, RRSIG, NSEC, NSEC3, IXFR, AXFR and ANY) and "other" which lumps together all other types.- The
response_rcode_count_totalhas an extra labelrcodewhich 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).
Restarting CoreDNS will stop the monitoring. This is a bug. Also this upstream Caddy bug.
Syntax
prometheus
For each zone that you want to see metrics for.
It optionally takes an address to which the metrics are exported; the default
is localhost:9153. The metrics path is fixed to /metrics.
