> What I've found is that the host dependency has the following behavior:
> 
> Nagios goes to check host A
> Nagios sees host A has a dependency on host B
> Nagios checks host B
> If all is good, Nagios checks host A
> 
> With parents:
> 
> Nagios checks host A
> If host A fails, Nagios checks the parents of host A
> ...repeat...(nagios walks up the dependency tree of parents of parents until
> it 
> gets to the top)
> 
> So, for something like a network switch, you want a parent relationship --
> you 
> don't want it to check the switch each time it checks the machine, only if
> the 
> machine fails, then check to see if it's the machine or if it's the switch.
> 
> We don't use host dependencies here, but we use service dependencies and we 
> definitely use parent relationships.
