Title: Distributed Monitoring - Redundancy

Hello Everyone,

Im running Nagios is a distributed environment which is working very well. I would like to add a little redundancy to the picture now that I have everything working. ;-)

Since Im running a distributed environment, how can I add a secondary Central-Server to the picture? Im not worried about the sensors or remote Nagios servers, just the central portion of the network. The problems that I see are as follows:

The remote servers send data via NSCA to the central server. Would they also have to send a second connection to the secondary server?

NDO now sends data to my MySQL server, will the secondary server also need to send data? This opens a can of worms in terms of duplicate data, etc.

It seems that a secondary cold spare might be the best solution. Then there are maintenance issues with keeping software up to data, etc.

So many problems, so little beer.

Thanks in advance,

Mike
