Overview

Circuit Data Metering enables customers to proactively avoid ISP data overage charges by monitoring and enforcing data usage limits on individual WAN circuits. When a configured data threshold is reached, the circuit can be automatically blocked, forcing traffic to route over alternate WAN paths.
 

Key Features

• Enable data metering at the WAN circuit levelConfigure data usage thresholds per billing period
• Automatically block circuits when thresholds are reached
• Manually block or unblock metered circuit
• Generate alerts as usage approaches and reaches limits
• Display circuit usage reporting at single‑site and multi‑site levels

Requirements

• Router firmware 1.2.1+
• Super Admin or Company Admin role

Circuit Configuration

To configure circuit data metering navigate to Site-> Site Configuration -> Circuits
Data metering can be configured on each WAN; however, it is strongly recommended that at least one WAN circuit remains without data metering to ensure continued connectivity if metered circuits are blocked.

Stop all Traffic Toggle

By default, automatic blocking is enabled for data metered circuits. When enabled, the circuit will be automatically blocked once it reaches the configured data threshold within the billing period.

This toggle can be disabled to allow the circuit to continue operating while usage is monitored through the UI and alerts, enabling you to manually block the circuit if and when needed.

Data Threshold

A data usage threshold defined in GB or MB

Once the configured threshold is reached, enforcement actions are applied automatically. It is reccomended

Billing Period / Reset Date

Specify a billing reset date

Reset will occur at 00:00:00 UTC

Circuit Blocking & Unblocking

Automatic Blocking/Unblocking
When a circuit reaches 100% of its configured data threshold, the circuit will enter a new ‘Blocked’ state and traffic will be forced to alternate WAN paths. The circuit will be automatically unblocked when the billing reset date occurs.

Manual Blocking/Unblocking

You may also manually block or unblock a circuit at any time.

Alerting

Circuit Data Metering generates alerts based on usage progression.

• Medium Severity Alert is triggered at 90% of the configured data threshold. 
• High Severity Alert is triggered when the threshold is reached and the circuit is blocked.

Alerts will remain active until the billing period ends or data metering configuration is changed or if the circuit is manually unblocked

Usage Reporting

Multi‑Site Reporting

Circuit table displays total data usage and percentage of threshold used

Included in CSV exports from the circuits table, which allows easy sorting/filtering many circuits

Single‑Site Reporting

Usage displayed directly on the Site Overview circuit widget

Shows total data consumed and percentage of configured threshold

Important Notes 

Bigleaf Cloud Connect (BCC) circuit data monitoring is not guaranteed to exactly match ISP‑reported usage for the same circuit. If data overages are a major concern, it is recommended to conservatively set the data limit threshold to a lower value to account for potential discrepancies.

Bigleaf Cloud Connect (BCC) can only track data usage for circuits that are actively connected to the Bigleaf router WAN port. If a circuit is disconnected from the WAN port, any data consumed outside of the Bigleaf router is not measured or accounted for in Circuit Data Metering.

Automatic circuit blocking is not instantaneous. When usage exceeds the configured threshold, BCC detects the overage and sends a command to the router to block the circuit. This process may take a couple of minutes, during which additional data usage (and potential overages) may occur. If overages are a major concern, it is recommended to conservatively set the data threshold to a lower value.

When a circuit is blocked, all traffic to and from the WAN port is blocked except for the Bigleaf configuration port. This is intentional and ensures the circuit can still be managed and manually unblocked even if it is the only available circuit. Data usage from configuration traffic is minimal and should not materially impact usage totals.
