How to totally uninstall nagios ?

What is the procedure to totally uninstall XI and start with a fresh install??

If you are going to start totally fresh, it would be best to re-install the OS to a clean minimal install then follow the manual install instructions.

Wow, that answer just made my decision to not purchase Nagios.

Starting with a fresh system is not so difficult and it's not unreasonable - after all we do require that you install Nagios on a "clean" system. Ideally, you shouldn't have anything else installed on this system anyway:

Important: Nagios Enterprises highly recommends and will only support installing Nagios XI on a newly installed, "clean" system. Attempting to install Nagios XI on a pre-existing system with other applications already installed can cause the Nagios XI 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 XI 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 XI to function. If you choose to ignore these warnings, you do so at your own risk.

We do have an uninstall script but it hasn't been updated lately and to be honest, I am not sure how well it works. There is not much interest in uninstalling nagios, so we put our priorities on different projects. Here is the document you need:

Hope this helps.
