Data Plan Throttling Data Plan Throttling
Design Design
This creates a rudimentary, but stable, data plan throttle that will disable any/all LAN traffic on a
device if it detects that it has gone over its monthly data usage limit. This is achieved by
leveraging the data usage API available on aView. The main benefit is the API tracks data usage
across reboots, so we can accurately measure the data usage over time.
This feature is implemented using a custom script. See example setup below. Note that the
user must specify their API token in the custom script. They can also adjust the data limit
(default is 100MB) and the rollover day for the data plan (default is the first day of the month).
If the data plan limit is reached for the month, this script will disable the LAN interface by
default (you can change script to disable passthrough mode instead). Similarly, when the
device is within/under its data plan limit for the month, this script will ensure the LAN (or
passthrough, if specified) interface is disabled.
Config Setup Config Setup
Create a new custom script under System -> Scheduled tasks -> custom scripts System -> Scheduled tasks -> custom scripts , and enter in the
following. The top three lines should be adjusted to put in the users API token from aView, the
desired data plan limit in bytes, and the rollover day of the month.
Keep in mind that each user in aView only gets 100 API requests every 15 minutes, so don't
adjust this interval down so low to the point that the user runs out of API queries (e.g. running
this script on 100 devices every 5 minutes equals 300 requests per 15-min, which is more than
the API limit).
