Does anybody have any recommendation for network monitoring and analyzing tools for an enterprise. I have 1 6509 at the core of my network and work like to monitor, do baselining and trending. I have several VLANS and want to see what's going on. I have looked into nGenius, but seems rather expensive especially after you buy all the probes.

Free demo available at the web site. Give it a try. You can have a map up in about 30 minutes. You can also monitor applications specific applications such as SMTP and HTTP.
