Best practices for running Nagios across multiple data centers

Thanks much for the suggestions!

I'll give Merlin and Multisite some thought.  Neither one of them seems 
to be in the CentOS (or EPEL) repos though, which makes me a little 
reluctant.

I also read up a bit on the Nagios NSCA option too, and it may not be as 
bad to configure as I thought, so I might wind up going with that.  Will 
run some experiments later today.

Thanks again for the pointers!

Installation's a snap, and flexible recovery options mean your data is safe,
secure and there when you need it. Data protection magic?
