[Observium] How to exclude some network interfaces?

Hi,

I deployed Observium over the weekend to try out. Reading through documents, I figured out how to exclude specific interface types. However trying to figure out how to exclude a specific interface? E.g. The list might be Fa0/30, Fa0/37, Gig0/9, Gig0/42. No contiguous interface.

Thanks in advance, Sam
