Parent/child config

[Scott Whitney]

It was my understanding that if a HOST was down, no services would be
checked.

I've got:

Nagios -> NAT Router -> Cisco Router -> Rack Router -> Host -> a slew of
services

What's the purpose of having parent/child relationships with hosts if the
service checks are not suspended if a host is down?

That is, I thought the flowthrough was:

Let us assume I'm checking a service on MyHost:

1) Check the NAT Router host.  If he's up, continue.
2) Check Cisco Router host...
n) etc.
n+1) Check MyHost.  Is he up?  If so, check the service.

This, I thought, was all controlled from 2 places:
1) Definition of service on MyHost.cfg in services
2) Definition of host on MyHost.cfg in hosts.

The host entry has parents, and if any of those hosts are down, aren't
service checks suspended?

I think you're looking for dependencies and not parent/child...

Actually, Skip, I was just thinking about reposting, since, no, I did
not
get anything back.

Anyone?

Scott,

Did you get any feedback on this problem?  I'd like to set up something
similar, but based upon your report I'm skeptical it will be of any use.

Thx,

Today, my local Cisco router went down.  Call it hw-router. :)  Well, I
have
a bunch of machines defined as "coloc-host".  Here's what the foo.cfg
file
says:
------------------
define host {
  use                             coloc-host

  host_name                  foo
  alias                           foo
  address                      vvv.xxx.yyy.zzz
}
-----------------

Here's what the hosts.cfg file says:

------------------
define host {
  name                            coloc-host
  notifications_enabled           1
  event_handler_enabled           1
  flap_detection_enabled          1
  process_perf_data               1
  retain_status_information       1
  retain_nonstatus_information    1

  check_command                   check-host-alive
  max_check_attempts              3
  notification_interval           1
  notification_period             24x7
  notification_options            d,u,r

  parents                         sw-router, hw-router, coloc-router
  register                        0
}
--------------------------

Well, when hw-router went down, when it came back up, I got about a
dozen
pages telling me that each of the coloc hosts was down, and then back
up. I
thought it wasn't supposed to do this to me, based on the config above.
Any
help would be appreciated.
