bvandeusenandClaude Opus 5.5	bf017e65c2	feat(traefik): scrape every Traefik replica behind the metrics URL and add them up (#5844) ... Through one address Steward read whichever replica answered, and with host-mode ports behind a keepalived VIP that can be the replica serving nothing: since the 18:43 restart every scrape landed on Docker03's idle Traefik, which has no traefik_service_* series, so no router was stored. A metrics_url host name that resolves to several addresses (a swarm service's tasks.<service>, a Kubernetes headless Service, round-robin DNS) is now scraped address by address, with the original Host header and TLS name. Answers from one process are kept once; a replica that doesn't answer is skipped with a warning. Requests, bytes and latency buckets are summed over the replicas that have a baseline, so the sum's rise is the sum of each one's own rise; certificates are listed once; Traefik's own figures add connections and memory and keep the newest reload. A name with one address is one scrape, as before. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-15 14:55:54 -04:00
bvandeusenandClaude Opus 5.5	98440d8de6	fix(traefik): count each Traefik process only against its own last scrape (#5844) ... One metrics URL can reach several Traefik processes: a swarm service's replicas behind the routing mesh or its VIP, a Kubernetes Service's pods, a keepalived pair after failover, or the same Traefik after a restart. Each keeps its own counters, so comparing one with another read the second one's lifetime totals as new traffic: retired routers flashed 100% 502 and an idle router showed 834 req/s whenever the scrape moved to the other replica. Each scrape is now keyed by Traefik's process_start_time_seconds and compared only with the same process's previous scrape. A process seen for the first time (or not in the last hour) sets its baseline and counts nothing. Without a start time every scrape is one process, as before.
