Summary
ntopng is a network traffic probe for monitoring and exploring network activity. It collects traffic information from traffic mirrors, NetFlow exporters, SNMP devices, firewall logs, and intrusion detection systems. An encrypted web interface provides real-time and historical traffic exploration, while nDPI-powered detection identifies more than 450 Layer-7 application protocols. Performance metrics include application latency, round-trip time, throughput, TCP retransmissions, packet loss, and VoIP jitter and MOS. The software captures packets with libpcap or PF_RING and gathers flows from nProbe, NetFlow, and sFlow exporters. Its HTTP-based REST API and Lua scriptability support integration and customization. The free Community edition is suggested for up to 256 live local hosts, 128K live flows, and eight monitored interfaces. Paid licenses are perpetual and include one year of maintenance; Pro is 299.00 EUR per once. LDAP and OpenID Connect login, multiple-interface aggregation, and specified alert integrations are for Pro and higher editions.
