Net Flow: IT Monitoring Service

Posted in Cisco NetFlow, Flexible NetFlow, Flow Analytics, Network Traffic Monitor on March 9th, 2012 by James FT
net-flow-it-monitoring-service

First of all, Net Flow  is spelled NetFlow, and today, we’re going to talk about an IT Monitoring Service that provides Network Traffic Monitoring.  Specifically, we want to monitor BYOD Traffic.  The modern workplace is often being assaulted by these devices.  Why? Androids and iPhones are constantly searching for a Network to connect to.  Once attached, some employees are so ‘connected’ with friends that these smart phones start flooding the network and pestering the user to participate in Facebook, Farmville or even Scrabble.  How can you find out when, what and where they are doing?

Posted in IPFIX on December 1st, 2011 by Aaron
juniper-junos-ipfix-support

Move over JFlow, Juniper is now has supporting IPFIX.  Juniper IPFIX exports include some neat stuff that we didn’t see in JFlow.  If you are not aware, JFlow is basically a rename of NetFlow.  IPFIX is the proposed standard for NetFlow and is supported by vendors such as Cisco, Citrix, Extreme, nBox, Plixer and SonicWALL. How do you get IPFIX from your Juniper hardware?

Vyatta: NetFlow Support

Posted in NetFlow, NetFlow Analyzer, Network Monitoring, Network Traffic Analysis, Network Traffic Monitor, sFlow on September 1st, 2011 by danny
vyatta-netflow-support

Vyatta Logo ImageVyatta NetFlow has been improved in some of the latest VC 6.x releases. I worked on a NetFlow reporting issue with a VC 6.0 user in the past trying to figure out why his NetFlow Analyzer was not showing the expected amount of traffic. We used Wireshark and found that a large number of flow packets were being exported without flow data, therefore were useless and discarded by the collector. Since he upgraded to VC 6.2, he was able to see all his traffic. Vyatta now supports MAC addresses, as seen in the image below! Read more »

NetFlow: Monitoring Network Behavior

Posted in NetFlow Analyzer, Network Monitoring, Network Traffic Analysis on August 3rd, 2011 by danny
netflow-monitoring-network-behavior
NetFlow data provides great insight into network traffic; however, due to its volume, if the right analysis tool is not being used, some critical network health information can stay hidden. I’ve seen NetFlow collectors that receive over 3000 flows per second from dozens and sometimes hundreds of devices. With this kind of flow volume you need an application that goes beyond reporting so that you don’t spend time staring at utilization graphs, protocols and thousands of IP addresses.

netflow-data-analysis-dissecting-traffic-flows

I personnally believe NetFlow v9 and now IPFIX are two of the greatest, if not the greatest, revolution in network traffic monitoring. It makes a substantial amount of usefull traffic information available to the network administrator. However,  to truly take advantage of  NetFlow, a software with powerful reporting capabilities is required. Today, I would like to talk about our NetFlow Analyzer data filtering capability.
