[Observium] Checkpoint Firewall Support?

I'm just starting to look at observium for some monitoring. I see that it supports cisco based firewalls (ASA/PIX) but it does not currently support checkpoint.

Checkpoint mainly runs on top of redhat linux. I'm able to get the general linux stats but not the firewall specific stats (connections/vpn/etc) similar to what's available with the cisco asa support.

Basically, I'm asking if anyone has managed to get this to work. Or barring that, any information as to how to add support?
