One of the greatest strengths of ntopng is its ability to correlate data originating at different layers and at multiple sources together. For example, ntopng can look at IP packets, Ethernet frames and, at the same time, poll SNMP devices. This enables ntopng to effectively perform correlations and observe: The behavior of IP addresses (e.g., […]
ntopng 4.0: A Refreshed Look with Dark Themes!
The latest ntopng 4.0 has a renewed look. The main changes we have introduced are: An always-on-top status bar. Key information on the health and status of the network is essential for the analyst and it must be always visible and easily accessible. This is why we have introduced an always-on-top fixed status bar with […]
Active Monitoring in ntopng 4.0: ICMP, ICMPv6, HTTP and HTTPS pings with RTT
The latest stable ntopng 4.0 features a Round Trip Time (RTT) monitor which is capable of pinging hosts on a minute-by-minute basis to check: IP reachability with ICMP and ICMPv6 pings Web servers functionality with HTTP and HTTPS pings Checks account for the RTT, that is, the time it takes to reach a certain host […]
Say Hello To ntopng 4.0: Cybersecurity, Scripting… and a New User Interface
After over one year of work, we’re proud to announce you that ntopng 4.0 is finally out. In this time we have redesigned ntopng for speed and openness, by breaking apart the existing monolithic C++ engine into a Lua-scriptable micro-engine. This is to enable people to contribute to the project without them being scared of […]
Important Geolocation Changes in ntop Products
ntop products have been using geolocation databases provided by MaxMind for a long time, to augment network IP addresses with geographical coordinates (cities, countries) and information on the Autonomous Systems. ntop have been freely packaging and redistributing such databases in ntopng-data. Unfortunately, new privacy regulations, such as GDPR and CCPA, place restrictions that impact our […]
Merging Infrastructure and Traffic Monitoring: Integrating ntopng with Icinga
Icinga2 is an open source monitoring system which checks the availability of hosts and services, notifies users of outages and generates performance data for reporting. Thanks to its scalability and extensibility, it has become very popular (as Nagios successor) and suitable to monitor complex environments, even across multiple locations. Although popular, it falls short when […]
Containers and Networks Visibility with ntopng and InfluxDB
For a while we have investigated how to combine system and network monitoring in a simple and effective way. In 2014 we have done a few experiments with Sysdig, and recently thanks to eBPF we have revamped our work to exploit this technology as well to be able to monitoring containerised environments. Months ago we […]
Measuring nProbe ElasticSearch Flow Export Performance
nProbe (via its export plugin) supports ElasticSearch flows export. Setting up nProbe for the ElasticSearch export is a breeze, it just boils down to specifying option –elastic. For example, to export NetFlow flows collected on port 2058 (–collector-port 2058) to an ElasticSearch cluster running on localhost port 9200, one can use the following nprobe -i […]
System-Introspected Network and Container Visibility: A Quick Start Guide
Recently, we have introduced the concept of network and container visibility through system introspection and also demonstrated its feasibility with an opensource library libebpfflow. In other words, by leveraging certain functionalities of the linux operating system, we are able to detect, count and measure the network activity that is taking place on a certain host. […]
Telemetry Data in ntopng: Giving Back to the Community
The latest ntopng 3.9 dev gives you the possibility to choose whether to send telemetry data back to ntop. We collect and analyze telemetry data to diagnose ntopng issues and make sure it’s functioning properly. In other words, telemetry data help us in finding and fixing certain bugs that may affect certain versions of ntopng. […]
