In nagios we can configure parents of hosts, so that if parent is down the childrens which depend on it are not checked. This is useful so that if switch is down the switches and machines behind it are not checked. This also helps in generating good graphical map of dependencies in nagios GUI
To configure parent just one line in host definition stating parents of the host is enough. Example config is
define host{
use generic-switch ; Inherit default values from a template
host_name 10.4.4.251 ; The name we're giving to this switch
alias Linksys SGE 2000 switch kept in GH ground floor, This is distribution switch for GH. ; A longer name associated with the switch
address 10.4.4.251 ; IP address of the switch
hostgroups switches,linksys-switches ; Host groups this switch is associated with
parents 172.16.30.1
}
Here 172.16.30.1 is treated as parent for 10.4.4.251, so that if 172.16.30.1 is down then 10.4.4.251 is not checked and assumed to be down.
