nProbe has been originally designed as an efficient tool able to capture traffic packets and transform them into flows. Call it network probe or sensor. Over the years we have added the ability to collect flows (i.e. nProbe is both a probe and a collector), so that nProbe can now act as probe, collector, also […]
Clustering Network Devices using ntopng Host Pools
In computer networks, devices are identified by an IP and a MAC. The IP can be dynamically assigned (so it might not be persistent), whereas the MAC is (in theory) unique and persistent for identifying a device. Non-technical users, do not know these low-level details, and in general it makes sense to cluster devices using […]
Flow-Based Monitoring, Troubleshooting and Security using nProbe
nProbe is a tool developed over the last 10 years, and thus it has been extended and improved year by year. However many users, even those who are using it since a long time, might not know all its features. Next week at Flocon 2017, I will give a talk about nProbe. The idea is to […]
Monitoring VoIP Traffic with nProbe and ntopng
VoIP applications usually limit theirs monitoring capabilities to the generation of CDR (Call Data Records) that are used for the generation of billing/consumption data. In essence you know how many calls a certain user/number has made, the duration etc. While this information can be enough for basic monitoring, it is not enough for guaranteeing reliable […]
ntop Users Meeting 2016 Retrospective
Earlier this week we have organised a ntop user’s workshop hosted at Sharkfest EU 2016. For those who have not been able to attend this session, below you can find the slides we have used for presentation. Introduction ntopng: Web-based Traffic Analysis nDPI: Open Source Deep Packet Inspection PF_RING: High-Speed Traffic Processing Hands-On Session Product […]
See You Next Week at the ntop Users Meeting
This is to renew the invitation to meet you next week at the ntop users meeting colocated with Sharkfest Europe. The event is free of charge but seats are limited. More information can be found here. Hope too see you next week at the workshop!
ntop and Kentik bring nProbe to the Cloud
Traditionally nProbe is used as a host-based network monitoring probe able to produce “augmented” flow records including performance monitoring, security and visibility information. We have a common vision with Kentik of how network instrumentation needs to evolve beyond “just” bytes and packets-based NetFlow, and of how that can enable users to understand network performance and […]
You’re Invited to the ntop Users Meeting and (free) Tutorial
Earlier this year we have held a ntop meetup in USA. Now we want to invite you to attend the ntop users meeting that will take place on October 17th (2 PM-5 PM), during the SharkFest Europe 2016 conference. The idea is to meet the ntop community, present our tools, highlight future work items and teach […]
Flow-based Monitoring: nProbe Cento vs Standard/Pro
Since the introduction of nProbe Cento, we receive periodically emails of users wondering what are the differences between these two applications. This post is to clarify the differences, and better position them. The nProbe family is a set of flow-oriented applications, meaning that each packet is not handled individually but as part of a flow (e.g. […]
ntopng 2.6 Roadmap
As we have released 2.4, it is now time to plan for the next release and highlight the list of features we plan to implement so we can start a discussion and get some feedback. The major changes we would like to introduce include: Rework interface views to make them more efficient and not an […]
