Getting the DNS zone expiration time

Hello :)

Thanks for the suggestion. Could you clarify what you mean by "DNS zone expiration time"?

1. The SOA expire field : the duration a secondary nameserver keeps serving the zone if it loses contact with the primary (a DNS protocol-level value), or
2. The domain name registration expiration date (from the registrar), which is already covered by our separate Protocol WHOIS connector, exposing a domain.expires.seconds metric with configurable thresholds.

The DNS Service connector's request mode already supports querying SOA records (--search-type=SOA), but it currently only extracts the primary nameserver field (mname), not the other SOA fields like expire, refresh, retry or serial. If it's option 1, this would require extending the connector to expose additional SOA fields as metrics.

Best regards.
