With traffic charts gone from the console, deploy/grafana/fancy-dns.json is where they live: queries by outcome, transport and client group, latency quantiles, RCODEs, cache hits/misses/stale, the upstream round trips saved by coalescing and early refresh, upstream health and latency, blocklist and zone sizes, and (in a Loki row) the blocked/failed-query access log. A node variable spreads or narrows every panel, and the per-node panel shows whether load is even across pods. A test reads the dashboard and fails if a panel queries a metric the resolver does not export, so a rename cannot silently empty a panel. The ingress no longer needs the SSE buffering/timeout annotations, and the statefulset comments no longer describe a query log on the volume. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
