This is to announce that the registration for the ntop Conference 2023, 25 years since the first release of ntop, is now open. Similar to past conferences, this event is divided into two days: the first day will be allocated for training on ntop products, the second day for the main conference and workshop. You […]
Deploying nEdge with Multiple (Virtual) LANs (and WANs)
Exactly 3 years elapsed from the introduction of nEdge (ntopng Edge), and despite the fact we haven’t posted much about it in our blog, this tool continued to grow, many features have been added over time, and we see that every time new users have the chance to try it, they are amazed about the capabilities it provides. […]
Using Traffic Rules To Supervise Network Traffic
The Problem Let’s assume that you have a Network where local hosts generate a constant amount of traffic. How do you find if they are misbehaving? It happens that some local host starts behaving strangely, by having an abnormal amount of traffic (sent or received) with respect to their recent past: how can you spot […]

Monitoring Microsoft Teams Performance and Video/Call Quality
Months ago we have talked how ntopng identifies ad monitors Zoom calls quality. Today we show how call monitoring has been now seamlessly extended to Microsoft Teams. Thanks to nDPI, ntopng is now able to detect Teams calls and to label them according to the stream type: Video Audio Screen Sharing. For each call it […]

Scaling Up ntopng Flow and Packet Processing
As traffic rate increases, it is important to tune packet processing in order to avoid drops and thus educe visibility. This post will show you a few tricks for improving the overall performance and better exploit modern multicore systems. The Problem ntopng packet processing performance depends on the number of ingress pps (packets per second) […]
Introducing Modbus Traffic Monitoring in ntopng
Modbus is an industrial protocol used to communicate with automation devices. The initial protocol version was implemented over a serial layer, whereas the current version named ModbusTCP is a variant of the original protocol running over TCP/IP. This blog post describes how ntopng monitors ModbusTCP traffic: it detects Modbus flows via nDPI and dissects them […]
Enabling Zeek and Suricata On-Demand at 40/100 Gbit using PF_RING
Overview Those of you who have some experience with IDS or IPS systems, like Zeek and Suricata, are probably aware of how CPU intensive and memory consuming those applications are due to the nature of the activities they carry on (e.g. signatures matching). This leads to high system load and packet loss when the packet […]
OpenAPI: ntopng REST API for Software Developers
Maybe not all of you know that ntopng powers in some popular monitoring systems such as CheckMK and Centreon. The integration is made possible through the ntopng REST API (REST stands for REpresentational State Transfer) that allows developers to manipulate ntopng configuration and query monitored information including hosts, flows, alerts and historical data. Recently we […]
