You are right, but disabling the alarm would mean i get no alarms at all.
For example the "Device Down" alarm:
If i disable the alarm for the time of maintenance, i get no alarms at all from no device except,
if i create a seperate alarm group for every single device.
Than your suggestion would work, so tha i disable the alarms processing only for a selected device.
But this is only for one alarm on one device, so this scales alittle bit bad.
Any mor esuggestions ??
