I have Nagios installed on a RHEL 4 64bit server and it has been running great. I want to install NagVis so I can create my own views. I installed Mysql successfully, but am having an issue getting the NDO2DB daemon to start. I run the command "/usr/local/nagios/bin/ndo2db-2x -c /usr/local/nagios/etc/ndo2db.cfg" and it gives a message "Support for the specified databaseserver is either not yet supported, or was found on your system." Not sure where to go from here. I tried reinstalling Mysql-devel rpm, but still no luck. The ndo2db.cfg file appears to be configured correctly. Any suggestions?
