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. … Continue reading
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 … Continue reading
Stream That Flow: How to Publish nProbe/Cento Flows in a Kafka Cluster
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
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 … Continue reading
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 … Continue reading
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, … Continue reading
Introducing nProbe Cento: a 1/10/40/100 Gbit NetFlow/IPFIX Probe, Traffic Classifier, and Packet Shunter
Traditionally ntop has focused on passive traffic analysis. However we have realized that the traffic monitoring world has changed and looking at network flows is no longer enough: People want to enforce policies: if the network is hit by a security threat you need to … Continue reading
Introducing nProbe 7.4
This to announce the release of nProbe 7.4. We have worked hard in this version to improve it in several way by better integrating it with ntopng, improving network performance metrics computation, ability to export data to big-data systems, make … Continue reading
Advanced Flow Collection with ntopng and nProbe
In flow-based monitoring there are two main components: the probe (a.k.a. flow exporter) and the flow collector/analyser. Usually NetFlow/sFlow is a push mode paradigm as network devices have almost no memory/storage and thus they send out data as soon as possible … Continue reading
How to Build a 100$/€ “Augmented” NetFlow/IPFIX Probe
One of main problems of flow-based devices is their high cost or poor monitoring capabilities (nothing beyond IPv4 packets and bytes). At ntop we believe that network visibility is much more than this, as people in 2016 want application performance, … Continue reading
