Monitoring CoreDNS involves a suite of key metrics that help track the health and performance of your DNS servers:
NOERROR or NXDOMAIN.| Metric Name | Description |
|---|---|
| coredns.dns_request_count_total | Number of DNS Requests processed per second |
| coredns.dns_responses_count_total | Number of DNS Responses issued per second |
| coredns.dns_request_count_total_per_status | Processed vs. Dropped DNS Requests |
| coredns.dns_responses_count_total_per_rcode | DNS Responses per Rcode, indicating response success or failure |
| coredns.dns_no_matching_zone_dropped_total | Requests dropped due to no matching DNS zone |
| coredns.dns_panic_count_total | Server panics due to internal errors |
