ntop (stylized as ntop) is computer software that probes a computer network to show network use in a way similar to what the program top does for processes. In interactive mode, it displays the network status on the user's terminal. In Web mode, it acts as a web server, creating a HTML dump of the network status. It supports a NetFlow-sFlow emitter-collector, a Hypertext Transfer Protocol (HTTP) based client interface for creating ntop-centric monitoring applications, and RRDtool (RRD) for persistently storing traffic statistics.
ntop is available for both Unix and Win32-based platforms. It has been developed by Luca Deri, an Italian research scientist and network manager at University of Pisa.
Common usage on a GNU/Linux system is to start the ntop daemon (/etc/init.d/ntopd start), then one can use the web interface to ntop via visiting http://127.0.0.1:3000 provided the loopback device has been started (/etc/init.d/net.lo start) and the listening port for ntop is 3000 (look out for the -w option in ps aux | grep ntop).
