[Observium] PPPoE Interfaces Deleted

Hi guys,

Please if anyone could offer some advice or guidance I would really appreciate it.

I recently deployed Observium in my network for monitoring purposes, everything is working great, better than ever expected, except for the following:

Each time a PPPoE client interfaces reconnects, the previous data is deleted, interface is deleted and the graphs and usage data start fresh from the time of the new connection.

Is there any way of setting up the Observium installation to retain previous session data and usage and just have it "carry on" recording data each time the PPPoE session reconnects?

Any assistance will be appreciated.

Thanking you in advance

Shaun
