Nagios Support Forum

Hi Team,

We have installed NagiosXI monitoring on a server. Now we are planning to installed Nagios Log Server on the same server. In your installation guide we read the following.

Installation Prerequisites
Important: Nagios Enterprises highly recommends and will only support installing Nagios Log Server on a newly installed, “clean” system (a bare minimal install with nothing else installed or configured).
Attempting to install Nagios Log Server on a pre-existing system with other applications already installed can cause the Nagios Log Server installation process to fail, critical system components and settings (e.g. database servers) to be modified in a way that negatively affects other applications, and previously installed applications to be automatically upgraded or removed. While installing Log Server on a system with other applications is possible, it is not recommended due to the possible interactions and complexity of multiple components that are required for Nagios Log Server to function. If you choose to ignore these warnings, you do so at your own risk.

Can we use the same monitoring server to install the Nagios Log Server?

Regards,
Nilesh

From your quoted text:

Nagios Enterprises highly recommends and will only support installing Nagios Log Server on a newly installed, “clean” system (a bare minimal install with nothing else installed or configured).

If Nagios XI already exists on the system, then from the perspective of Nagios Log Server the system is not "clean" or a "bare minimal install with nothing else installed or configured".

Nagios Log Server should be installed on its own and not with XI.
