[Observium] scaling graphs through variable

Hi,

in our WAN we have multiple 100's ALIX boards connected through VPN. On eth1 we can scan all the info on the sublocations. On eth0 & eth2 we have various internet (local breakouts) connections with sometimes async ADSL modems.

Is it somehow possible to retrieve a variable (that i have to insert manually / firewall) like ifAlias? It would be ideal to have up & download links per eth0 / eth2 parsed into scaling graphs on the ports tab.

This way i can make alerts as we have no bandwidth throttling

Regards, Martijn
