Greg.. thats how i have it I pretty much every single module in cc plus ntop, dolphin, email, 3 websites ftp server vpn and also nagios. anyhow, nagios does not run with cc or intergrate with it at all but you are able to run it on the same box. but you just use the gui to access it localhost/nagios
or whatever you want to have it set as. Its also not setup like ntop although it can be which is what im working on now, and it still using less resources compared to ntop.
