Distributed Nagios Setup

[uaslam]

What we have...
Two NagiosXI enterprise servers at two different locations. Both locations have a site to site VPN in between. Both servers monitor exactly the same hosts/services across the two locations. Currently only one server sends out notifications.
What we want (ideally)
Have a redundant setup.
If possible, we would like for each server to run checks local to it and send notifications but if one server goes down, the other should take on its responsibilities.
At the very least, If the server sending notifications goes down we would like the other to do its job.

We do have experience setting up mod_gearman for check distribution. Just looking for basic idea on how to approach this...

Thanks!

Hello uaslam,

I'd take a look at this document for a overview of options that can get you started in a "HA" environment:

I am going to steal a quote from Andy on this one:

Most of our high availability (HA) clients implement failover on a lower level than the XI software - usually db replication and HW/OS level clustering like DRDB or Linux HA.

This was really helpful to me. Posting here if anyone else comes across this thread.
