[Observium] Alert Checker options

Hi All

Is there a way of removing a subset of device names from the alert checker configs, i.e.

!somename.* *

or NOT EQUAL somename.* *

or similar so if there are devices that I want to graph, but dont care if they are up or down.

Which brings me to another point I guess, is there a way of not showing certain things on the dashboard or diminishing the value / time of a notified device,

I dont need to know about a rebooted device for 24 hours,

also is there are 2 or 3 errors on an interface I may not need to know about them, and as per above I may only want to graph traffic on a device if it is up, and dont need to know if it isnt up
