Database error occured
Re: Database error occured
What version of CentOS or Red Hat was NNA installed on, and are these 'clean' systems with nothing else installed or configured?
Also, the Nagios Network Analyzer requires PHP version 5.3 or higher - refer to our install doc is you haven't already:
https://assets.nagios.com/downloads/nag ... ctions.pdf
If everything checks out, then lets gather some info. Please provide the following with your next reply, thanks!

Re: Database error occured
Thanks for that info, the problem is you've installed NNA on a server already running Nagios XI. This is not supported and each must be installed on their own server. Hopefully you have another server available on which to install NNA and more importantly, this will not cause problems with your existing XI installation. To avoid the latter, definitely remove anything NNA related from this server.

Re: Database error occured
Can you detail to me how to uninstall Network Analyzer from the server please?
Re: Database error occured
Here you go --
1) delete the nagiosna directory and all of it's sub directories
.../usr/local/nagiosna
2) delete nagiosna from init.d
.../etc/rc.d/init.d/nagiosna
3) in /tmp delete all 'nagiosna' items
Afterwards, check if anything else remains, run:
find -name nagiosna
