Best practices for running Nagios across multiple data centers

[David Rosenstrauch]

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!

Simplify data backup and recovery for your virtual environment with vRanger.
Installation's a snap, and flexible recovery options mean your data is safe,
secure and there when you need it. Data protection magic?
