Yeah, I've done that. Just does seem to be pretty redundant to send out UNREACHABLE alerts when a parent is DOWN, imo... :-) It has it's benefits. That's why it can be enabled and disabled, just like all the other notification types. -- Marc - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

[Nagios-users] Nested notifications; parent vis-a-vis parent_host
Hey nagios people,
Assume I have a happy system of a hypervisor and virtual machines.
Further, there's a neat system of when a machine goes down an SMS and
email is sent to the responsible person.
However, when the parent machine goes down, all the VMs (for obvious
reasons) send out a Oh Noes! message as well. This is not wanted.
Now the nagios documentation, dating back from the netsaint days, says
the system to walk a dependency path using parent_host... however the
hosts.cfg has entries like the following:
define host{
use generic-host; Name of host
template to use
host_name guestvm1
alias guestvm1
address xxx.xxx.xxx.xxx
parents xendom0
check_command check-host-alive
}
Now presumably, cgis like statusmap.cgi is built from this information.
Would changing 'parents' to 'parent_map' in the above fix the dependency
walk and notifications? And would it break statusmap.cgi?
Thanks in advance,
Lev
