ntopng, high speed web based network traffic monitoring with per host and per flow visibility, ready on first boot.
ntopng is a web based network traffic monitor that shows what is happening on your network in real time. It captures traffic from a network interface, identifies applications and protocols with deep packet inspection, and presents per host and per flow statistics, talkers, alerts and historical trends through an interactive dashboard, with support for collecting NetFlow, sFlow and IPFIX flows from other devices.
cloudimg ships ntopng community edition fully patched with its redis backing store already wired up, so the dashboard is serving traffic the moment the VM boots. No known password is baked into the image: a unique admin password is generated on this VM's first boot, and every image comes with a paired deployment guide and 24/7 support.
