Monitor draws CPU, memory, GPUs, requests, tokens, latency, network and disk as Braille charts over 5m/1h/24h/7d, then per node, card and model sparklines; node and model pages have their own. History is read from monitoring.prometheus through POST /api/v1/metrics/range, or without it from what the console saw. The control plane serves the cluster's machines for Prometheus http_sd at /prometheus/targets on its metrics port, and node add installs prometheus-node-exporter.
