Pppoe interface

Hi.
I need to monitor the pppoe interfaces of an rb1100 x4, but I can not get the software to register them, despite using the line unset ($ config ['device_traffic_iftype']); $ config ['device_traffic_iftype'] [] = '/ pppo /';

Any ideas.

Thanks.

I made a debug of Poller.php, and I see what the poller Ignore the interfaces.
How can I do, for the poller.php add this interfaces to the system?

Config.php

$config['device_traffic_iftype'][] = '/ppp/';
$config['device_traffic_iftype'][] = '/mpls/';
$config['device_traffic_iftype'][] = '/pppoe/';
