A few months ago, with ntopng 3.8, we introduced support for continuous traffic recording, that allows you to drill down historical data from the timeseries level up to raw packets. This is useful when troubleshooting a network issue or analysing a … Continue reading
New Challenges in DPI Protocol Detection
In the early Internet days, each network protocol was designed for a specific purpose: SMTP for sending emails, HTTP for the web and so on. In order to make sure that implementations where compliant with the specification, there was an … Continue reading
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 … Continue reading
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 … Continue reading
Building a (Cheap) Continuous Packet Recorder using n2disk and PF_RING [Part 2]
Continuous packet recorders are devices that capture raw traffic to disk, providing a window into network history, that allows you to go back in time when a network event occurs, and analyse traffic up to the packet level to find … Continue reading
Introducing PF_RING Configuration Wizard
Getting started with PF_RING can be a bit tricky as it requires the creation of a few configuration files in order to setup the service, especially when ZC drivers need to be used. First of all it requires packages installation: … Continue reading
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 … Continue reading
Introducing nProbe Agent: Packetless, System-Introspected Network Visibility
A few months ago at FOSDEM we introduced the concept of network and container visibility through system introspection and we released an opensource library based on eBPF that can be used for this scope. Based on this technology, we created a lightweight … Continue reading
Talking about Network, Service, and Container Monitoring at InfluxDays
Later this week the ntop team will attend InfluxDays, June 13-14, London, UK. We’ll be talking about traffic monitoring in containerised environments, and give you an outlook of our roadmap. If you are attending this event (we’ll have a … Continue reading
