Customers can now see what they have used and what is left, and the service
slows down rather than stopping when the allowance is gone — a slow Nextcloud
gets a top-up, a dead one gets a cancellation.
- instance_traffic keeps one row per instance per month. Proxmox counters are
cumulative since the VM last started, so usage is the difference between two
samples, and a counter that went backwards means a restart, not a refund.
- Outbound is what counts: inbound is free at our providers and egress is what
Hetzner's 20 TB per server applies to.
- CollectInstanceTraffic samples every 15 minutes, warns once per threshold
(80/95 %) rather than on every run, and at 100 % limits the VM's NIC via
Proxmox — released again as soon as the customer tops up or the month rolls
over.
- The dashboard gets a full-width band (it throttles the service, so it is not
a tile among tiles) with the top-up offer right next to the warning.
- Bytes are formatted in SI units now: allowances are computed in SI, so
dividing by 1024 made a 1000 GB plan read as "931 GB".
