[Observium] global template settings

Hi,

first time user of observium and i like the info that i can get with it.

The documentation is probably behind the "client-area" @ observium.org?

I have no idea if it matters whenever i change the type from "server" to "firewall", does it apply other MIB's to the device?

I am trying to figure out how i can minimize the amount of polling bandwidth. I see there is a "global-setting" or "device-setting" but how to modify those globally @ template?

Regards,

Martijn
