I'm not sure if I compiled Nagios with MYSQL support or not and need to find out if I did before I install a plug-in. Is there a way to determine if I did?
Also, if it turns out that I didn't what must I do to enable MYSQL support? My Nagios install is configured and already monitoring several servers so I don't want to lose all that work I put into it (this was my first time installing it). Will I need to uninstall Nagios and re-compile it with MYSQL support if I failed to do so the first time? If I end up having to go that route, what steps must I take to ensure the new install will work properly as before? And will I need to change anything in Apache etc?
(this is on a Slackware 12.1 box by the way)
