If I understand this right, the "parents" option is used for Nagios itself (prehaps better re-worded as "internally") to define the network topology for the core host check. If the switch is down, it won't mark a host as Down, only as Unreachable. For a "host dependency", I have to define something like this: define hostdependency{ host_name Host A dependent_host_name Host C notification_failure_criteria d } define hostdependency{ host_name Host B dependent_host_name Host C notification_failure_criteria d,u } Am I understanding this right? What gets me is that what Nagios seems to call a parent is, to me anyway, a network/host dependency. Hosts are dependent on the network and services are dependent on hosts. I guess I'm missing where a "host dependency" would actually be of any value... <pre class="moz-signature" cols="72"> A.
