May 17th 2010 Press Release Plixer International, Inc., a leading global provider of network traffic monitoring and analysis tools, today announced that it has partnered with NTOP of Italy to launch Scrutinizer 7.7 with nProbe™ support for advanced flow-based monitoring to analyze client, server and application latency. If the flow involves HTTP, the URL information […]
Extending ntop using Python
ntop was designed to be self-contained in order to avoid people configuration and usage headache. Unfortunately the drawback is that extending ntop has always been a difficult activity as users had to code in C and know ntop’s internals. Recently thanks to the integration of ntop with Python, it is possible to script the application […]
Meet ntop @ Florence (May 9th): Opening-up ntop using Python
Pycon Conference Florence, May 7-9 2010 ntop (https://www.ntop.org) is an open-source project aimed at monitoring network traffic. Recently, in order to make the tool even more flexible than before this for letting people adapt it to their needs, the python interpreter has been embedded into ntop. The result is that users can now use python […]
Meet ntop @ Zürich (June 23rd): Large-scale Flow Monitoring Through Open Source Software
AIMS 2010 Conference Tutorial Zürich, June 21-25, 2010 Large and high-speed networks produce a large number of flows that need to be collected and analyzed. Most collectors are unable to keep up with the flow export rate, and also have severe speed limitations when creating reports, due to the amount of data that needs to […]
10 Gbit PF_RING-based Hardware Packet Filtering and Balancing Previewed at the Intel Europe Conference
Intel Research Europe Conference, Bruxelles, May 4th 2010 Luca Deri and Joseph Gasparakis, senior Intel engineer, have previewed a new PF_RING-based technology they have co-developed that allows Linux users to fully exploit the hardware capabilities of the newest Intel X520 10 Gbit adapter (based on Intel 82599 controller). This technology that is close to public […]
Meet ntop @ Bolzano (May 20th): Conference on Nagios, NTOP @ OSS Monitoring featuring Ethan Galstad an Luca Deri
Following the great interest in 2009, the successful series of an international Conferences on Nagios, NTOP and OSS Monitoring will continue also in 2010. Therefore the organization team of Würth Phoenix spared no efforts to top last year’s agenda and bring international Nagios and OSS Monitoring experts to Bolzano/Italy. This way, next to Nagios founder […]
IANA Assigned a PEN to ntop
Internet Assigned Numbers Authority (IANA) has assigned to ntop the 35632 PEN (Private Enterprise Number) number. This means for instance that nProbe extensions (e.g. HTTP and VoIP traffic monitoring) will be exported using IPFIX using a valid template that will be recognized by all flow collectors available in the market. A side effect is that […]
Collection and Exploration of Large Data Monitoring Sets Using nProbe
Collecting and exploring monitoring data is becoming increasingly challenging as networks become larger and faster. Solutions based on both SQL-databases and specialized binary formats do not scale well as the amount of monitoring information increases. This paper presents a novel approach to the problem by using a bitmap database that allowed the authors to implement […]
ZDNet.de: ntop: ein bedeutsames Tool fuer die Netzwerkanalyse
ZDNet.de speaks about ntop.
PF_RING and Transparent Mode
PF_RING has been designed for enhancing packet capture performance. This means that the RX path must be accelerated, and in particular a way to accelerate this is by reducing the journey of the packet from the adapter to userland. This is obtained by allowing the driver to push the packet from the NIC to PF_RING […]
