Even though Flow data has different names, they all provide mostly the same information and work in similar ways.

HP and Fortinet use “ sFlow” standard which we've covered here. NetFlow software collects and analyzes this flow data generated by routers, and presents it in a user-friendly format.Ī few other network vendors have their own protocols for network traffic data monitoring and collecting.įor example, Juniper, another highly respected network device vendor, calls their protocol “J-Flow.” The term “ NetFlow” refers to a Cisco proprietary protocol for collecting information about IP traffic and for monitoring network traffic NetFlow has become the industry standard protocol for flow technologies.

nProbe A NetFlow probe and collector that is usually partnered with a separate front-end data analyzer.

Runs on Linux, Windows, macOS, and Solaris.

Wireshark A widely-used free network packet sniffer that includes a packet viewer with a protocol analyzer.

Installs as a virtual machine or can be taken as a cloud service.

Plixer Scrutinizer A traffic analyzer with strong intrusion detection features.

Noction Flow Analyzer This package of network traffic monitoring and capacity planning services by focusing on data extracted from switches and routers with a range of communications protocols, including NetFlow.

Here is our list of the Top Free NetFlow Analyzers and Collectors: NetFlow analyzers allow you to pinpoint machines and devices that are hogging bandwidth, to find bottlenecks in your system, and, ultimately, to improve your network’s overall efficiency. NetFlow Analyzers and Collectors are very useful tools to assist in monitoring and analyzing network traffic data to help you manage these issues and potentially stop them before they become major problems. So the question then comes: what is NetFlow and what are Network Analyzers? This is where analyzing network traffic comes in handy using packet sniffing techniques. As Network engineers and Administrators, many of us are consistently dealing with issues that aren't always as apparent as they seem.
