Browse code skydick/monitoring: drop InfluxDB zpool_io, add Prometheus pool-member map The Grafana dashboards (skynet-web on door1) query Prometheus, not InfluxDB — nothing queries skydick's InfluxDB — so the zpool_io telegraf collector fed nothing. Replace it with a node-exporter textfile metric skyw_zpool_member{pool, device}, refreshed from live `zpool status` each run. Grafana joins it onto node_disk__completed_total to get honest physical* per-pool IOPS, drift-proof against kernel device renames (unlike a hardcoded device regex).

The Grafana dashboards (skynet-web on door1) query Prometheus, not InfluxDB —
nothing queries skydick's InfluxDB — so the zpool_io telegraf collector fed
nothing. Replace it with a node-exporter textfile metric skyw_zpool_member{pool,
device}, refreshed from live `zpool status` each run. Grafana joins it onto
node_disk_*_completed_total to get honest *physical* per-pool IOPS, drift-proof
against kernel device renames (unlike a hardcoded device regex).
