Sondes actives ICMP/HTTP/DNS qui complètent le monitoring passif
(node_exporter + up{}) : joignabilité hôtes/passerelle, accès internet,
santé DNS *.lab.local + forwarding, latence LAN, services de bout en
bout via Traefik.
- blackbox_exporter (chart 11.13.0, ArgoCD, ns monitoring) — ICMP via
NET_RAW, DNS du pod = dnsmasq (chemin réel lab → Traefik)
- 3 jobs blackbox-icmp/-http/-dns (additionalScrapeConfigs)
- alerts-network.yaml : internet, DNS, passerelle, hôtes, services,
latence, exporter (→ pipeline AlertManager existant)
- Asa : outil network_status + contexte présélectionnable reseau
- doc admin/infra/reseau.md + CLAUDE.md + progress
