user traffic

Somebody knows how can I get user traffic to built a graphic? . My intention is to create an applications in Java to check on line user traffic (like hotspot active traffic graphics).
Thanks in avance for your help.

Well you can use the Tool, Graphing and give the IP of the machine doing the java script access to ALL queues, if the user has a queue, he will start graphing once you add this. Now another way is to enable SNMP and use a program like MRTG (free, easy to find on the web) to pull the data to a folder, then graph it for you, but you could also then use the Java Applet to pull the data file and do what you want with the data.

Thank you so much, I´ll work about your sugestion.
