Nagios Support Forum

Hello,

I was reading some of the documentations but was a little confused. Right now we have a single Nagios XI server in a VM that is monitoring our environment. I am wanting to see what a proper way to setup Nagios in a HA Cluster.

Should we spin up a new VM, install the Nagios XI software on there and have separate disks between them, or should we create a new VM and share the disks between the two VMs with clustering software with RHEL?

For a step by step guide, check out https://www.linbit.com/en/576-ha-nagios ... -on-rhel7/. There are however otherway to setup HA:

I think the majority of people set up separate disks and rely on replicating the data between machines instead of using a shared disk.
