#5254 "Traefik — Routers: current routers only, header row, certs on the router they serve". - Router hosts come from Traefik's API (/api/http|tcp/routers), read best-effort on each scrape. An optional api_url overrides it; the default is /api on the metrics host. A certificate's expiry then shows in a TLS column on the router whose host it covers. An expiring one makes that router a problem, graded by Settings → Thresholds. - Only current: routers and certificates must have appeared in the last three scrapes. Certificates are upserted by serial and never deleted, so renewed or retired ones lingered on the widget. - Widget order: verdict, problem routers with the reason, then the busiest healthy routers under one header (Router / Req/s / Bandwidth / p95 / TLS). A missing value shows "—". - If the API is unreachable, expiring certificates are listed after the routers, not above them. - The page splits certificates into served (with the routers using each, plus SANs) and "No longer served". - Latest row per router: an index walk (recursive CTE + LATERAL) replaces DISTINCT plus a query per router.
