- metrics table + Metric model; metrics:sample command (scheduled every minute,
pruned to 24h) records MQTT throughput (a Redis counter the ingest jobs bump)
and host CPU load + memory% from /proc.
- Chart.js line-chart Alpine island (themed from CSS tokens, dual axis) on the
Host page shows MQTT/min, CPU load and memory %. wire:ignore so the 10s health
poll doesn't re-init it. Nav check 10/10 clean (0 console errors).
