ManageEngine NetFlow Analyzer

ManageEngine ™ NetFlow Analyzer is a web-based bandwidth monitoring tool that performs in-depth traffic analysis using data exported from Netflow flows.

This data provides granular details about network traffic that has passed through an interface. NetFlow Analyzer processes this information to show you what applications are using bandwidth, who is using them, and when. Extensive graphs and reports make this information easy to analyze, and also help accelerate the troubleshooting process.

The minimum hardware requirements for NetFlow Analyzer to start running are listed below.

  • 2.4GHz, Pentium 4 processor, or equivalent
  • 1GB RAM
  • 10GB disk space for the database

Software Requirements

Platform Requirements

NetFlow Analyzer can be installed and run on the following operating systems and versions:

  • Windows 2000 Server/Professional with SP 4
  • Windows XP with SP 1
  • RedHat Linux 8.0, 9.0
  • SUSE Linux

Supported Web Browsers

NetFlow Analyzer has been tested to support the following web browsers and versions:

  • Internet Explorer 5.5 and later
  • Netscape 7.0 and later
  • Mozilla 1.5 and later

Ports Required

NetFlow Analyzer requires the following ports to be free:

Port Name Default Port Number Usage
Web server port 8080 This is the port on which you will connect to the NetFlow Analyzer server from a web browser. You can change this at any time from the Settings tab.
NetFlow Listener port 9996 This is the port on which NetFlow exports are received from routers. You can change this at any time from the Settings tab.
MySQL port 13310 This is the port used to connect to the MySQL database in NetFlow Analyzer. Changing this port requires configuration level changes.

Recommended System Setup

Apart from the System Requirements, the following setup would ensure optimal performance from NetFlow Analyzer.

  • Run NetFlow Analyzer on a separate, dedicated PC or server. The software is resource-intensive, and a busy processor can cause problems in collecting NetFlow data.
  • Use the MySQL pre-bundled with NetFlow Analyzer that runs on port 13310. You need not start another separate instance of MySQL.

Changing the Default MySQL Port

    1. Edit the database_params.conf file present in the <NetFlowAnalyzer_Home>/conf directory.
    2. Change the port number in the following line to the desired port number:
      url=jdbc:mysql://localhost:13310/netflow

  • Save the file and restart the server.
