Query Explanation

The rule calculates, per Thanos‑rule job/instance, the percentage of DNS query failures by dividing the 5‑minute rate of thanos_rule_query_apis_dns_failures_total by the 5‑minute rate of thanos_rule_query_apis_dns_lookups_total and multiplying by 100; it fires when this percentage exceeds 1 %.
