[quote=“luca”]If a parent host is down, the “child” hosts get marked as unreachable and are NOT checked anymore, and so are their services.
So i’d say that yes, the “parents” directive is what you are looking for, at least staying to what i can understand from your first request.[/quote]
Yes this is correct, we were looking to add this stuff in to eliminate unwanted alerts. So I didn’t think the parent directive was going to offer that solution but you can add in the option to not alert on unreachable. That being said, Nagios does alert unreachable by default.
[quote]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.
