[Observium] Disable Monitoring of Linux Interfaces

Good Evening,

I was able to get Observium up and running with no issues, but I do have a bit of an odd situation. I happen to have a server that I wish to monitor that has over 300 PPP interfaces. Observium is attempting to poll them, and its hammering the server hard, and Observium. Is there a way to remove polling of interfaces (or maybe just ppp interfaces) on that server?

Thanks!
