Hi;
I'm not sure what I'm doing wrong.
Running nagios 2.5 on debian-stable. I have the nagios server in one
data center monitoring 30ish servers in another data center.
In the hosts.cfg file I have a gateway (firewall) defined:
define host {
use generic-host ; Name of host template
to use
host_name pix
alias PIX
address x.y.z.2
check_command check-host-alive
max_check_attempts 1
notification_interval 1
notification_period 24x7
notification_options d,u,r
}
I then use that as a parent to all the hosts I want to monitor in the
remote data center. Those have host entries like this;
define host {
use generic-host ; Name of host template
to use
host_name logweb1
alias Logweb1
address logweb1.foo.com
parents pix
max_check_attempts 1
active_checks_enabled 0
notification_interval 1
notification_period 24x7
notification_options d,r
}
As I read the documentation, when nagios detects that host "pix" is down
that it won't check or report on host logweb1.
If the network connection is broken, however, by deleting the default
route, I get three messages that the pix is down that look like this:
Subject:** PROBLEM alert 1 - PIX host is DOWN **
***** Nagios *****
Notification Type: PROBLEM
Host: PIX
State: DOWN for 0d 0h 0m 0s
Address: 66.151.232.2
Info:
CRITICAL - Network unreachable (x.y.z.2)

And a few minutes later I get notice on the child server:
Subject: ** PROBLEM alert 1 - Logweb1/Check Simple Webservers is CRITICAL **
***** Nagios *****
Notification Type: PROBLEM
Service: Check Simple Webservers
Host: Logweb1
State: CRITICAL for 0d 0h 8m 6s
Address: logweb1.foo.com
Info:
Network is unreachable

Thanks in advance,
