CPU, memory, disk, load, network, processes — collected by the agent every second, charted with proper p50 / p95 lines, kept for two years. Sparklines on every list, full charts on every host.
The metrics arrive because the agent is installed, not because someone wired up a node exporter and a scrape config.
An average CPU of 40% hides one core pinned at 100%. A total disk figure hides the one device with a queue.
Raw samples for the recent window, hourly aggregates beyond it, daily kept indefinitely — so last year is still answerable.
Free tier includes 7 days of native-res data; longer retention from Starter.
