Hello Guys,

I would like some advice on free monitoring tools that you are using to monitor your WAN.Specifically,I have several sites whose internet connections is terminated on Cisco ASA

5510,Cisco 1941/1841,Catalyst Switches and Cisco AP's.I would like to be able to capture traffic from this sites and analyze this so that i can determine 

                                                        I.            Who are our Top Talkers and who are they "talking" to in this sites

                                                        II.          What websites are routinely being visited and what is being downloaded

                                                      III.          If there are any  signs of rogue network applications or malicious activity on the network

                                                     IV.            Determine Top applications in use in a particular site and bandwidth requirements

Any ideas are appreciated!.



Regards!
