High-Speed Web-based Traffic Analysis and Flow Collection. ntopng is the next generation version of the original ntop, a network traffic probe that monitors network usage. 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.
Main Features Sort network traffic according to many criteria including IP address, port, L7 protocol, throughput, Autonomous Systems (ASs) Show realtime network traffic and active hosts Produce long-term reports for several network metrics including throughput and application protocols Top talkers (senders/receivers), top ASs, top L7 applications Monitor and report live throughput, network and application latencies, Round Trip Time (RTT), TCP statistics (retransmissions, out of order packets, packet lost), and bytes and packets transmitted Store on disk persistent traffic statistics to allow future explorations and post-mortem analyses Geolocate and overlay hosts in a geographical map Discover application protocols (Facebook, YouTube, BitTorrent, etc) by leveraging on nDPI, ntop Deep Packet Inspection (DPI) technology Characterise HTTP traffic by leveraging on characterisation services provided by Google and HTTP Blacklist. Analyse IP traffic and sort it according to the source/destination. Report IP protocol usage sorted by protocol type Produce HTML5/AJAX network traffic statistics. Full support for IPv4 and IPv6 Full Layer-2 support (including ARP statistics) GTP/GRE detunnelling Support for MySQL, ElasticSearch and LogStash export of monitored data Interactive historical exploration of monitored data exported to MySQL Alerts engine to capture anomalous and suspicious hosts SNMP v1/v2c support and continuous monitoring of SNMP devices
