Proxmox exposes canonical rrddata streams. Pick a horizon, choose average vs peak smoothing, and export any series as CSV for offline math.
rrddata
CPU pane: Shows guest CPU share as a percent of entitlement; CSV lists ISO timestamps with load.
Network pane: Plots ingress, egress, and a dashed P95 envelope of combined throughput.
Memory pane: Bytes in use; axis caps at provisioned RAM when the API reports it.
Disk pane: Read/write throughput—pair with the job console when chasing spikes.
Four synchronized canvases fed straight from the node RRD cache.
Auto-refresh every two minutes while this screen stays mounted.
