# Proxmox traffic accounting and limits per VM

NexoVirt counts the incoming and outgoing traffic of every Proxmox guest per month. When a guest reaches its limit, the panel notifies, throttles it to a speed you set or suspends it, and lifts that again at the next month, when you add gigabytes or lift the limit for the month.

## What it does

Monthly traffic per guest, with a warning, then notify, throttle or suspend.

- ### Counted per guest, per month

Received and sent traffic for every guest, from the collected metrics, kept for 13 months. The month follows the guest through a migration.
- ### Limits from guest, plan or default

A guest override wins over its plan, a plan over the global default. Count incoming, outgoing or both.
- ### A warning at 80 percent

One email, an inbox alert and a guest event before the limit is reached.
- ### Notify, throttle or suspend

At the limit the guest is only reported, throttled to a set speed, or shut down. Resellers can set their own throttle speed.
- ### Undone automatically

A new month, "Lift for this month" or extra gigabytes that bring usage under the limit restore the speed or start the guest again.
- ### Visible to customers

Customers see their usage on the server page. A traffic-suspended server cannot be started from the portal, admins and the API still can.

## Why not just use the Proxmox web UI?

Proxmox VE runs the virtualization. NexoVirt adds the layer around it. Traffic limits, task by task:

| Task | Proxmox web UI | NexoVirt |
|---|---|---|
| Monthly traffic of a VM | RRD graphs, no monthly total | A monthly total per guest, 13 months kept |
| Act on a traffic limit | Not available | Notify, throttle or suspend |
| Give a customer more traffic | Not available | Add gigabytes or lift for the month |

## How to use it

Up and running in 3 steps, all in the panel.

1. Set the default limit and action in Settings, Traffic, or per plan.
2. Override a single guest on its Limits pane when needed.
3. Watch the Traffic column in the guest list and the card on each guest page.

## Traffic limits FAQ

Is traffic counted for guests without a plan?Yes. Every guest is counted. The global default limit is 0 (unlimited) until you set one.

How is a throttled guest slowed down?NexoVirt sets a rate limit on the guest's network interface in Proxmox and puts the previous rate back when the throttle ends.
