SolarWinds NetFlow Traffic Analyzer EDITOR’S CHOICE This companion to the Network Performance Monitor collects traffic data from any network device using a range of protocols, including Cisco’s NetFlow.

Here is our list of the four best NetFlow analyzers: In other words, using NetFlow is a great way to monitor and troubleshoot your network.

Identifying abnormal levels of traffic is useful for diagnosing cyber attacks like DDoS attacks so the user can take steps to mitigate it ASAP.

For example, if there is an unusual spike in traffic then a NetFlow Analyzer will send you an alert. Devices compatible with NetFlow produce data that can be exported to a NetFlow collector/software agent.Īfter exporting NetFlow data, an administrator can use a NetFlow traffic analyzer to view visual representations of this flow data to gauge the performance of the network. NetFlow is a network protocol and Cisco IOS application that was developed by Cisco to collect and monitor traffic data generated by routers and switches (many routers have a NetFlow feature that automatically records NetFlow data). Yet for all these changes, NetFlow, a technology developed in the 1990s has remained a staple for network security and quality of service monitoring. Modern enterprises are using technology that is more complex and faster-pace. Under the disruptive influence of cloud computing and containerized technology, networks have become increasingly opaque.
