Understanding CoreDNS Performance Metrics
Monitoring CoreDNS involves a suite of key metrics that help track the health and performance of your DNS servers:
DNS Request Metrics
- coredns.dns_request_count_total: Number of DNS requests processed per second.
- coredns.dns_request_count_total_per_status: Differentiates between processed and dropped DNS requests.
DNS Response Metrics
- coredns.dns_responses_count_total: Number of DNS responses issued per second.
- coredns.dns_responses_count_total_per_rcode: Breakdown of responses by response code, such as
NOERRORorNXDOMAIN.
Performance and Stability Metrics
- coredns.dns_no_matching_zone_dropped_total: DNS requests dropped due to no matching zone.
- coredns.dns_panic_count_total: Number of server panics due to internal errors.
| 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 |
