Why

The TUI only shows configured resources. To see which guest needs more CPU, RAM or disk before it becomes a problem, you need what is actually in use.

Proposal

Main table: CPU % and memory used (MiB or %), from the data get guests already returns (cpu, mem, maxmem, disk).
Info screen, Resources section: "in use" next to each configured value, from status/current.
Optional: a short trend over the last hour from rrddata.

cv4pve-cli (2.4.0)

get guests -o json. It already has cpu, mem, disk, maxmem and maxdisk.
api get /nodes/<node>/<qemu|lxc>/<vmid>/status/current -o json
get guest rrddata <node> <vmtype> <vmid> hour

Notes

For VMs, disk is usually 0 unless the guest agent reports it, so show "-" rather than a misleading 0.
/cluster/resources lags a few seconds behind.

Done when

Usage is shown in the table and on the info screen.
Tests are written first.
A read-only live check passes.
