NagiosXI Parent Child relationship

[itutd]

Can some on help me understand the Parent/Child relationship for Nagios. Is it something that I should use as I start to implement Nagios. Can you provide some examples of how this pertains to host and service monitoring

Thank You

On top of the added benefit of seting up the basis for most of the mapping utilities, parent child relationships are important in Nagios because it can establish if a host or service is reachable .

UNREACHABLE States and Notifications

By default, Nagios will notify contacts about both DOWN and UNREACHABLE host states. As an admin/tech, you might not want to get notifications about hosts that are UNREACHABLE. You know your network structure, and if Nagios notifies you that your router/firewall is down, you know that everything behind it is unreachable.

If you want to spare yourself from a flood of UNREACHABLE notifications during network outages, you can exclude the unreachable (u) option from the notification_options directive in your host definitions and/or the host_notification_options directive in your contact definitions.
