The first important step to start with network monitoring is to analyze what we want to monitor and how to deploy the monitoring solution in the existing network. Here are some important questions to ask ourselves before starting the actual monitoring: Do we need to monitor the entire network or just a specific segment? Do […]
nProbe 8.2 stable is out – A Wink At Next-Gen ASA Firewalls
We are pleased to announce that the new 8.2 release of nProbe is out. This release features full Cisco ASA NetFlow support. ASA are industry’s first threat-focused next-generation firewalls that export a rich set of information through NetFlow. Being able to collect ASA data using nProbe will give you an advantage over collectors that only interpret […]
When Live is not Enough: Connecting ntopng and nProbe via MySQL for Historical Flows Exploration
Using nProbe in combination with ntopng is a common practice. The benefits of this combination are manyfold and include: A complete decoupling of monitoring activities (taking place on the nProbe) from visualization tasks (taking place on ntopng); The capability of building distributed deployments where multiple (remote) nProbe instances send monitored data towards one or more […]
Introducing nProbe 8.0, the ntopng flow companion
The current nProbe 8.0 release contains many changes with respect to the 7.x series. We have optimised the code, added the ability to collect non standard fields (e.g. Cisco AVC), improved Kafka export, and reworked many tiny details to make the tool a stable solution for all those looking for a flexible and versatile flow […]
Webinar: Security Monitoring with 1:1 NetFlow and 100% Packet Capture
Latest news: Napatech has decided to reschedule the webinar. A new date will be announced when available. Thu May 23rd and 25th together with Napatech we have organised two webinars about monitoring network traffic using flow-based technologies. We will be talking about 100 Gbit network traffic monitoring. Flow-based monitoring including nProbe Cento. 100% packet capture […]
Collecting Proprietary Flows with nProbe
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 […]
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 […]
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 messaging system makes them good candidates source of network data. The delivery of network data to a […]
