What is the best NetFlow Analyzer?
In a product comparison, SolarWinds NTA ranks as the best NetFlow analyzer. Windows compatible, supportive of multiple alternative flow technologies, and extremely user-friendly, this tool has a real edge.
How does SolarWinds NetFlow traffic Analyzer work?
SolarWinds® NetFlow Traffic Analyzer (NTA) allows you to capture data from continuous streams of network traffic, and convert those raw numbers into easy-to-interpret charts and tables that quantify exactly how the corporate network is being used, by whom, and for what purpose.
What is a NetFlow analyzer?
A NetFlow analyzer is a tool deployed to perform monitoring, troubleshooting and in-depth inspection, interpretation, and synthesis of traffic flow data. Analyzing NetFlow facilitates more accurate capacity planning and ensures that resources are used appropriately in support of organizational goals.
Is NetFlow Analyzer free?
Analyze real-time network traffic – Free NetFlow traffic analyzer. NetFlow Analyzer is a free NetFlow network traffic analyzer and its customizable dashboard enables you to view widgets grouped by devices, interfaces, interface groups, or IP groups, and can also detect network anomalies at a glance.
What is NetFlow traffic?
NetFlow is a network protocol system created by Cisco that collects active IP network traffic as it flows in or out of an interface. The NetFlow data is then analyzed to create a picture of network traffic flow and volume — hence the name: NetFlow.
Does NetFlow affect performance?
NetFlow generation has a performance impact on the devices where it is turned on. To reduce that impact on performance, networking devices often rely on packet sampling to generate NetFlow statistics.
Does SolarWinds use NetFlow?
SolarWinds NetFlow Traffic Analyzer is built to be used with SolarWinds Network Performance Monitor (NPM) to allow flow data to be quickly compared against other network performance metrics for easier data correlation.
What tools are used for traffic analysis?

What can NetFlow tell you?
NetFlow is a network protocol developed by Cisco for collecting IP traffic information and monitoring network flow. By analyzing NetFlow data, you can get a picture of network traffic flow and volume.
How much traffic does NetFlow?
This depends on the number of conversations that are being summarized by NetFlow. According to Cisco, v9 and v5 exporters will use about 1.5% to 3% of the monitored interfaces bandwidth. The traffic will be proportional to the number of active conversations and the interface bandwidth.
Is NetFlow free?
The NetFlow Traffic Analyzer can communicate with network devices using the NetFlow, sFlow, J-Flow, NetStream, and IPFIX protocols. Although this tool is not free forever, however, you can start with a 30-day free trial.
How would you tell the difference between full PCAP and NetFlow?
In essence, with PCAP you need a more precise and focused query to achieve an optimal return, while NetFlow enables you to find out the “what and where” to query with. Plus, with flow data, you can easily and quickly query for everything gavin.
How do I convert PCAP to NetFlow?
How to run it?
- First download the tool from the link above.
- Do the usual Linux ./configure, then make followed by make install as root.
- The command pcap2flow mycapturefile.pcap 192.168.1.88 12055 will play out all Netflow packets in the capture file to the collector at 192.168.1.88 listening on port 12055.
How does ManageEngine NetFlow analyzer perform free network traffic analysis?
ManageEngine NetFlow Analyzer performs free network traffic analysis is by leveraging leading flow technologies such as NetFlow, sFlow, IPFIX, Netstream, J-Flow.
What is the Cisco NetFlow Protocol?
In 1996, Cisco released NetFlow as a network protocol to offer insight into all these areas within a cohesive operating environment. Used to collect information about your network IP traffic and to monitor network traffic activity, NetFlow generates insights into application flows.
What are the best NetFlow monitoring open source tools?
Another NetFlow monitoring open source tool, ntopng is a traffic analysis solution that captures packets to monitor flow data. To get the data, it relies on an open-source NetFlow collector called nProbe. The web-based interface consolidates packet data into flows.
What is the difference between NetFlow and SFlow?
If we think of network traffic as traffic on a highway, NetFlow is a wide-lens camera capturing all the lanes, whereas sFlow takes pictures of isolated vehicles as they pass. Only NetFlow will give you a clear and all-inclusive view of your data.
