Uninstall NagiosXI

[anasal]

I have installed Nagios Core and also NagiosXI on ubuntu 18.04. How to remove NagioxXI only?

Hello, @anasal. Nagios XI installation comes with the Nagios Core as well. I'm not sure whether you have 2 Core instances running at the same time, or whether XI started using the existing Core installation. But either way, running the uninstallation script is too risky in your case because it will most likely uninstall Core as well, thinking that its a part of the XI.

/usr/local/nagiosxi/scripts/uninstall_xi.sh

My recommendation is to copy the configs from the:

/usr/local/nagios/etc/

Wipe the server, install a new Nagios core from scratch and then import the old configs.
