Design question

[Hoot, Joseph]

I've implemented both solutions here.  I ran the failover model first
and ran it for about 2 years.  Now, I run both redundantly checking but
just without notifications on the secondary.  I do this so that in the
event that I want to check that my performance metrics (ala rrd graphs)
are seeing the same information, I cant easily just go to my secondary
and check what it looks like there.

But yeah... read up in the documentation because there are good examples
of setting it up either way.

Check out the documentation on Redundant and Failover Network Monitoring

(http://nagios.sourceforge.net/docs/3_0/redundancy.html).

Both examples will do what you want, but the underlying behavior is 
drastically different between the two so make sure you read carefully.
