Quick question for you all. I am wanting some type of correlation engine that will take input from various monitoring programs such as Nagios, OSSEC, Nessus, Snort, Cacti, etc. and put them in a pretty graph and all that good stuff. I have found some products such as OSSIM and PreludeIDS, but I didn't know if anyone had any other good solutions. And of course I am looking for the price to = $0. Thanks!
