Hello.
The reason that the interface is deleted and reappear as a new interface is probably beacuse your server change the ifindex for the interface each time. If you could configure your server to always use the same ifindex for this vpn then Observium would use the same rrd file and it will comeback with its traffic history as any other interface that goes down and then up.

Hallo,
i have the following problem.
I server of mine a VPN-Service.
This vpn-service restart some times (and with it it recreate a network
interface with the same name "vpn-interface").
Observium delete the interface and create a new one (with the same name).

The Question, is it possible to detect it and make a down up event out
of it (and a mac change)?
So it will use the same rrds, graphs and so on.



Nice Wishes
 Geno
