HowTo Extend ntopng with new Host/Flow Checks and Alerts
ntopng can be easily extended with new host/flow checks and alerts. They are developed in C++ with a few Lua files used by the UI to configure the check and format the emitted alerts. In order to introduce you to thir development, we have written a short guide that shows you step-by-step how to develop a simple check and alert. If you want you can see a code example of host check that rtiggers an alert when a server contacted a new port after a learning period. If you have …

HowTo Export ntopng Alarms to Checkmk Event Console
Checkmk is a popular platform for monitoring IT infrastructure. ntopng has been integrated in Checkmk some time ago, enabling users to provide traffic visibility in additional to classic bytes/packets metrics. As ntopng is able to produce traffic alerts that, we have decided to extend ntopng in order to export alert information towards Checkmk event console where alerts are received.This guide will walk you through configuring ntopng and Checkmk to enable this functionality. In order to do so, within ntopng, it’s necessary to configure a new Endpoints as well as a …

Advancements in Traffic Processing Using Programmable Hardware Flow Offload
This week we have presented at the IEEE HPSR (IEEE International Conference on High Performance Switching and Routing) our latest work that shows how nProbe can benefit of acceleration provided by modern SmartNICs to achieving multi-100 Gbit traffic processing (both passive and inline) on low-end servers while deep-packet inspecting traffic using nDPI. If you want to know more about it, you can view the presentation slides, or read thw paper. Your feedback is welcome. Enjoy ! …

Howto Build a (Cheaper) 100 Gbit Continuous Packet Recorder using Commodity Hardware
Those who follow this blog probably read a few posts where we described how to build a 100 Gbit continuous packet recorder using n2disk and PF_RING, providing specs for recommended hardware and sample configurations (if you missed them, read part 1, part 2 and part 3). In those posts we recommended the use of FPGA-based adapters (e.g. Napatech) with support for PCAP chunk mode (e.g. ability for the NIC to collapse packets onside the adapter in pcap format without the need to read packet-by-packet as with most network adapters), in addition …

InfluxDB v2 support in ntopng is Now (partially) Available
It’s been 3 years since InfluxDB v.2 was released and until a couple of months ago we didn’t plan to add the support to the InfluxDB v.2 due to many reasons: migration from SQL to Flux query language, v2 performance not better than v1. The in the meantime InfluxData release InfluxDB v3 that is currently only supported on their cloud and not yet packaged as on-prem product. However due to the more pressing requests and suggestions from our customers we finally decided to add the support as follows: as InfluxDB …

ELLIO for ntopng: HowTo Prevent CyberAccidents Using Blacklists
Time is one of the main problems in cybersecurity. Detecting issues after they have happened can cost you money and resources to restore the system. Network traffic monitoring tools have as goal to show what is happening on a network.  Traditionally, monitoring protocols such as IPFIX/NetFlow export monitoring data periodically and often limit their analysis to the protocol header, thus the flow collector is partially blind as it is informed after a certain event happened with limited contextual information. In ntop tools we operate in real-time with pre-labelled information thanks …
