Let me start off saying that I am
sorry this is so long but I wanted to include all of the necessary information:
OK. I am going absolutley crazy at
this point. I am getting "no
output" as a result of the following configuration for Nagios “failover”
as defined in the manual.
The following is a file I have created called
failover.cfg

In the nagios.log I have the following:

Here is what I get from the GUI for the service

hope that this helps someone point
me in the right direction.
