Setting passive fail over for primary Nagios XI

[nagiosfan]

I have one Nagios XI inside our LAN network and another XI that I just built and did not configure anything yet on AWS. There is already a tunnel between LAN network and AWS. I want to set up the Nagios XI on AWS as a passive failover so if the primary is down, the one on AWS is up and serves the monitoring job. I searched around but there is no official guidance that shows user how to do this task. I know [eople have different way to do this but those are for clusters in LAN network and I do not see anyone does with one in AWS and one in LAN network. I assume the setup should be alternatively same but I want to have a detailed guidance. I think Nagios should publish one guidance eventually.

Hello, @nagiosfan. That's a good idea. Although, I'm not sure if XI running on top of the AWS server bridged to the network would be different from a regular XI running locally on a network? Do you have any specific concerns?

There are well-documented ways of distributing traffic amongst machines so that a single XI machine does not have to do all of the work:

Or if you're looking to have multiple machines running the same configuration for failover purposes there are:
