NTOPNG - NETWORK TRAFFIC MONITER & USAGE

NTOPNG - NETWORK TRAFFIC MONITER & USAGE

ntopng is the next generation version of the original ntop, a network traffic probe that shows the network usage, similar to what the popular top Unix command does. ntopng is based on libpcap and it has been written in a portable way in order to virtually run on every Unix platform, MacOSX and on Windows as well.
ntopng users can use a a web browser to navigate through ntop (that acts as a web server) traffic information and get a dump of the network status. In the latter case, ntopng can be seen as a simple RMON-like agent with an embedded web interface. The use of:
  • a web interface.
  • limited configuration and administration via the web interface.
  • reduced CPU and memory usage (they vary according to network size and traffic).

What ntopng can do for me?
  • Sort network traffic according to many criteria including IP address, port, L7 protocol, throughput, AS.
  • Show network traffic and IPv4/v6 active hosts.
  • Produce long-term reports about various network metrics such as throughput, application protocols
  • Top X talkers/listeners, top ASs, top L7 applications.
  • For each communication flow report network/application latency/RTT, TCP stats (retransmissions, packets OOO, packet lost), bytes/packets
  • Store on disk persistent traffic statistics in RRD format.
  • Geolocate hosts and display reports according to host location.
  • Discover application protocols by leveraging on nDPI, ntop’s DPI framework.
  • Characterise HTTP traffic by leveraging on characterisation services provided by Google and HTTP Blacklist.
  • Show IP traffic distribution among the various protocols.
  • Analyse IP traffic and sort it according to the source/destination.
  • Display IP Traffic Subnet matrix (who’s talking to who?)
  • Report IP protocol usage sorted by protocol type.
  • Produce HTML5/AJAX network traffic statistics.
