Thanks for that.

My problem is : 

	I've lot of services/hosts under nagios (~1500) and when some
	building is out of power (so lots of host/services going down), the
	nagios go wrong because of the charge on the server. 

The first thing I think about is the parents/children but as you say that's
not going to change anything.

The second idea is to : 

	Use dependencies and put a set (like all servers in a building) of
	host/servers in dependence of top of switch. 

	And when the power come out, I put manually the top of the switch
	to down.

	What's do you think ? 

Regards.
