ntopng® is a web-based network traffic monitoring application released under GPLv3. It is the new incarnation of the original ntop written in 1998, and is now revamped in terms of performance, usability, and features. ntopng is a network traffic probe that provides 360° Network visibility, with its ability to gather traffic information from traffic mirrors, NetFlow exporters, SNMP devices, Firewall logs, and Intrusion Detection systems. ntopng has been written in a portable way in order to virtually run on every Unix platform, including Linux and FreeBSD, MacOS and on Windows as well. ntopng captures traffic from SPAN/mirror ports or TAP devices using libpcap, or PF_RING (on Linux) for best performance. Or you can use it in combination with nProbe to collect NetFlow/sFlow from routers and switches, or nProbe Cento to analyze 100 Gbit links at full rate.
Features
- Sort network traffic according to many criteria including IP address, port, Layer-7 (L7) application protocols, throughput, Autonomous Systems (ASs)
- Show realtime network traffic and active hosts
- Produce long-term reports for several network metrics including throughput and L7 application protocols
- Top talkers (senders/receivers), top ASs, top L7 application protocols
- 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
