+## Node-дашборды (диски/память/сеть/доступность) — этап 7, РЕШЕНО ✅
+
+На каждую ноду (vps01, vps02, vps03, bigbox) — **отдельный дашборд**,
+`grafana/dashboards/node-<host>.json` (uid `node-<host>`, title "Node <host>").
+Генерируются скриптом `/tmp/gen_nodes_dash.py` (в git не хранится; при желании
+перенести — в EXPERIENCE.md).
+
+Панели (все по `{host="<host>"}`, job=node):
+1. **Availability** — stat-панель `up{job="node",host=...}` (UP/DOWN)
+2. **Disk free (GB)** — `node_filesystem_avail_bytes` (без tmpfs/overlay/squashfs)
+3. **Memory available (GB)** — `node_memory_MemAvailable_bytes`
+4. **Load** — `node_load1/5/15`
+5. **Net <iface> RX/TX (bytes/s)** — `rate(node_network_{receive,transmit}_bytes_total[5m])`
+6. **Net <iface> utilization (%)** — `(rx+tx)*8/speed*100`
+
+Физические интерфейсы: vps01=eth0, vps02=enp3s0, vps03=ens1, bigbox=eno1.
+Контейнерные (docker0/veth*/br-*) не включены.
+
+Тонкость node-exporter 1.9: на виртуалках vps01/vps02 `node_network_speed_bytes`
+= **-125000** (sysfs speed=-1 → умножается на 125000), поэтому для них скорость
+линка захардкожена **125000000 Б/с (1 Gbit/s)** в формуле утилизации. На физических
+(vps03/bigbox) используется сама метрика `node_network_speed_bytes` (=1.25e+08).
