I hate it when this happens...
So, now the full story...
I did that, and then I see two links on the Status Map page. That is
OK. Now the question is: what is the result of this? What will happen
if one of the two parents goes down?
You see, what I have is this:
Nagios box:
IF A: 172.20.200.109
IF B: 10.30.66.66
Server:
IF A: 172.20.200.40
IF B: 10.30.66.10
10. goes to a router
172.20. goes to a switch
This server has the 10.30.66.10 IP as host_address. This is the IP of
the private GigaBit backbone that both this server and the nagios box
share.
Now, some service checks are done over the 10. network, and some are
done over the 172.20. network. However, since the server is defined
with its 10. IP, Nagios will only see this host as being down when it
receives no reply from that interface. It doesn't care about the other
one. So what would be the advantage of adding the switch on the
172.20. network as a parent, if you know that if that interface fails,
Nagios will not see it as a down host?
I hope you know what I mean...
