High-speed web-based traffic analysis and flow collection using ntopng. Persistent traffic statistics in RRD format. Layer 7 analysis by leveraging on nDPI, an Open Source DPI framework.
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 … Continue reading →
Apache Kafka can be used across an organization to collect data from multiple sources and make them available in standard format to multiple consumers, including Hadoop, Apache HBase, and Apache Solr. nProbe — and it’s ultra-high-speed sibling nProbe cento — integration with the Kafka … Continue reading →
ntopng uses partitioned MySQL tables when storing flows. As MySQL needs a file handle for each partition and its index, it is important to make sure that the open_files_limit is large enough to allow the process to keep all these files … Continue reading →
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 … Continue reading →
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 … Continue reading →
In a previous post we introduced our new nBPF library that able to convert a BPF filter to hardware rules for offloading traffic filtering to the network card. We did not mention that the same engine can be used for accelerating traffic extraction from … Continue reading →
Modern network adapters such as Exablaze, Napatech and Silicom’s Intel FM10K, support hardware filters. Unfortunately every company has its own way to set filters, no unified API, and no support of any BPF-like filters. Most of the network monitoring community … Continue reading →
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 … Continue reading →
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 … Continue reading →
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, … Continue reading →
