Nagios Failover system with state sync - possible?

[Fred]

I would bet if you replicate your nagios configuration to another
node and have your status.sav file on common highly available storage
and the main monitoring node fails, a backup node could start nagios
using the same configuration and pick right up more or less ...

You don't need replication, but even if you did, you could probably just
sync out the status.sav file (assuming you have nagios configured to
flush it out in a reasonable interval, the default is 15seconds I think)
and then copy the status.sav file to the backup node just in case.
