The bulk of my systems are behind one of three switches. I just went
through my hosts.cfg file and added the "parents" line and appropriate
switch name for each, but the host dependencies aren't showing up. I do
use a host template for most of the servers and then other specifics.
Below is a sample of what's defined. Initially I thought the issue was
the Nagios server being in the same switch as one of the switches, but
the last entry below shows a switch defined as a parent and the Nagios
server is not behind the switch (Nagios is behind flscrb234srvsw5, the
last host is behind flscrb234srvsw6). The VLAN is the same for all the
hosts in the three switches... all hosts operate on 10.1.1.x/16 or
10.1.80.x/16 which is all a single VLAN. I'd appreciate any thoughts on
why it might not be working:
