2. ManageEngine NetFlow Analyzer (FREE TRIAL)

ManageEngine NetFlow Analyzer

ManageEngine NetFlow Analyzer is a bandwidth monitor that identifies the capacity of each link on your network and then watches traffic flows to see whether any stretches are approaching overloading.

Key Features

  • On-premises system for Windows Server and Linux
  • Uses NetFlow, sFlow, J-Flow, IPFIX, NetStream, AppFlow, and FNF protocols
  • Displays traffic problems
  • Alerts to attract technicians

This tool doesn’t look at the cable – network cable can’t provide feedback. Instead, it examines the interfaces of the switches on the network. Each switch logs all of its throughput capacity as it copies data from one port to another. The NetFlow Analyzer extracts this data as it gets recorded on the switch.

Switches communicate their traffic statistics through a built-in query language and different manufacturers use different standards for this function. NetFlow Analyzer can communicate with the NetFlow, sFlow, J-Flow, IPFIX, NetStream, AppFlow, and FNF protocols. Those statistics break down by source and destination and also protocol, so the NetFlow Analyzer dashboard is able to show segmented data as well as overall traffic statistics.

The traffic analysis protocols used by switches also enable the NetFlow Analyzer to extract passing packet headers, either as a flow or as samples. The NetFlow Analyzer includes packet analysis screens that enable you to sort and filer packet headers to identify traffic from specific sources or applications. It can also highlight the exchanges in conversations between two endpoints.


  • Supports multiple protocols like NetFlow, great for monitoring Cisco equipment
  • Both tools work well alongside each other to help view traffic patterns and bandwidth usage
  • Easy to use interface automatically highlights bandwidth hogs and other network traffic outliers
  • Can proactively monitor switch port status to identify failing ports and misconfigurations


  • Built for enterprise use, not designed for small home networks

The NetFlow Analyzer is a software package that installs on Windows Server and Linux. It is available in three editions: Free, Essential, and Enterprise. The Free edition is limited to monitoring only two interfaces. The Essential edition is designed to monitor a single site and multi-site businesses should opt for the Enterprise edition because that has distributed monitoring capabilities. You can get a 30-day free trial of ManageEngine NetFlow Analyzer.
