Ansible roles: - node_exporter : déploie node_exporter v1.9.1 sur storage-01 et gpu-01 avec textfile collector + services systemd. ROCm activé sur gpu-01 uniquement via group_vars. Collecte métriques GPU via sysfs (temp, VRAM, utilisation) — pas de dépendance rocm-smi (remplacé dans ROCm 7.x) - alertmanager_webhook : service Python sur storage-01 (:9093/webhook) reçoit alertes AlertManager et les route vers ask-agent monitor → Hermes Playbooks: node_exporter + alertmanager_webhook ajoutés à storage-01 et gpu-01 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
