Hi
because a Hardware failure of our Nagios Server, i used the chance to upgrade vom Nagios 3 too 4
Since then Nagios Parents behavior is a bit strange
We check around 800 Hosts with 1200 Services.
I would love to add more but my couriosity with Notifications from Child objects, stops me there
To tell you what is going on
Lets say we habe 3 Hosts and one Host has 2 Services
Firewall
!
!
Switch1 (Parent of FW)
!
Switch2 (Parent of Switch1)
+
++Switch2 Service1
++Switch2 Service2
If the Firewall goes down and up again
I still will get EMails that Switch1 and 2 are offline
If Switch2 goes Offline
I still get E-Mails that Service1 and 2 is not reachable
It seems like my "Parent" setting doesnt work
OR Host and Service wont cross check
Lets say like
Host is down but Nagios will check in 5 minutes and THEN changes from ON too down
But in the meantime Service check happens and it sends e-mail about not reachable
Is there a way too fix that?
Or was i even able to make myself clear

Re: Nagios 4.3.1 Parents
I think I understand what you are saying, and based on that I think you have the "parents" backwards. You should setup the parents base on looking at the network through the eyes ogf the nagios server.
Here is a doc that outlines with pictures and config snippets how to set this up

The key is putting your nagios server in your diagram, to see what things should look like.
One thing of note, is that if a parent is down you will still get unreachable notices if you have them turned on, but unreachable is a different message than down, implying that a parent, grandparent, etc is down.

Hey
thank you i wil read your link and check my settings.
The most reasonable part could be the unreachable mails
