Nagios Support Forum

I am having trouble finding a comprehensive guide on setting up redundant Nagios servers.
The closest I've found is:
https://allmybase.com/2010/10/04/settin ... s-servers/
But this does not seem to cater to non-Linux experts. He makes a lot of assumptions that I'm not able to follow.
There are easier to follow guides out there but they all make it clear that they have shortfalls and are not the ideal way to go about it.
Could anyone provide a link to a better quide on setting up redundant Nagios servers?
Thanks!

It's certainly a non-trivial problem to solve that will require some Linux expertise. We don't have much documentation on HA setups. Linbit is who we usually guide people towards when they have such questions.

There have been a few speakers at past conferences that have discussed the topic:
