Distributed Monitoring - Redundancy

[Mike Koponick]

Hello Everyone,

I'm 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 I'm running a distributed environment, how can I add a secondary
"Central-Server" to the picture? I'm 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
