I am working with Nagios 4.0.7 on two servers to monitor my network. Recently I developed the third one in order to have more redundancy so I start reading information about failover redundancy mostly with NSCA. Has anyone a little bit of experience in this domain that could tell me which is the most efficient and easy way to do it. I read this slides that already helped me a lot but of course the issue is still the time synchronization between the master and the slaves:
Is NSCA the best option?Is failover, redundancy or the use of both the best choice?
