    • Central Server Host Name - You have to enter the Central Server Host name or the IP address of the Machine where the Central Server is installed so that Collector can contact Central Server.
      Note - Make sure that the value specified for the above field is reachable from the Collector.
    • Https Port - This is the port through which the collector communicates with the Central Server
      Note - Please specify the same Https port that you gave while installing the Central Server so that collector communicates with the Central Server Properly.
  6. Proxy server details - If the collector is behind a proxy please specify the necessary details.
  7. Once the above steps are followed, NetFlow Analyzer Collector gets successfully installed under the folder that you specified.
  8. Before starting the collector, please tune the java and mysql parameters according to your machine configuration. For your convenience we have already added various configurations for java and mysql parameters.
  9. run.bat/sh file contains the Java parameters which is present under the /bin directory of the collector installation. startDB.bat/sh file contains the mysql parameters which is present under the /bin directory of the collector installation. You can tune them by uncommenting the required and commenting the others. run.bat tuning will not take effect while starting a service.

  1. What are the core components of the Enterprise Edition ?
    A typical Enterprise Edition deployment consists of a single Central Server installation on a dedicated machine & multiple collector installations.
    The Central Server
    • manages the collectors
    • does data management
    • generates scheduled reports
    • provides a centralized web console
    The Collector
    • is deployed  near the routers
    • collects the NetFlow data from routers
    • processes NetFlow
    • compresses the resultant and sends to Central Server

  2. Can I install the Central Server and Collector on the same machine?
  3. There is no technical reason to not install them on the same machine. But, it is recommended to install them in dedicated machines to get better performance in production environment. However, you can install them on the same machine for evaluation purposes. Make sure that the web server port is different for both.

  4. Can I run Central Server and Collector in different OS?
    Yes. We have successfully tested NetFlow Analyzer Enterprise Edition in Windows 2000 server, Windows XP, Windows Vista, Windows 2003 server and in popular Linux flavors like Redhat Linux 8, 9 etc. We don't support FreeBSD yet. Also you could run the Central Server on a 64-bit machine and Collector on a 32-bit machine and vice-versa.

  5. Which one should I start first - Central Server or Collector?
    For the first time, Central Server must be started before the Collectors are started. However, later on they can be started and shutdown independent of each other/in any order.

  6. What are the default ports that the Enterprise Edition uses ?
    The default ports used by Central Server are as follows:
    • Web server port : 80
    • Https port used for enabling communication with collectors: 443
    • MySQL port: 33306
    The default ports used by Collectors are as follows:
    • Web server port : 80
    • NetFlow Listener port : 9996 (max of five ports can be given. E.g. 9995,9996,9997,9998,9999 )
    • MySQL port: 33307
  7. What are the installation steps for the Central Server and the Collector ?
    Central Server and Collector are two separate installations. You need to download Central Server & collector separately. Central Server can be installed on any OS & any machine (32 bit / 64 bit) and collector can be installed on any OS & any machine(32 bit / 64 bit). It is recommended to install Central Server & collector in two different machines to extract better performance.

    The communication between Central Server & collector is one way communication, i.e. only collector can communicate with the Central Server. Collector communicates through the https port of Central Server. Hence you should specify the same https port given for Central Server installation, while installing the collector. If the collectors are spread across geographically, it is advised to install the Central Server in a public IP address machine or NAT the machine & https port. Make sure that no firewall is blocking the collector from communicating with the Central Server and also please check if any firewall is blocking the NetFlow packets from reaching the collector. In case the collector is deployed behind a proxy server, please provide the proxy server details, while installing the collector.
  8. Can Central Server & Collectors be in different time zones?
    Yes. But the data can be viewed only at Central Server time zone.

  9. Should the time in Central Server and all Collectors be the same?
    No, but ensure that Central Server shows the correct time, since the Collectors adopts the Central Server time.

  10. Can I use a separate external database server for Central Server?
    The database bundled with our product is tuned for best performance. Hence we don't recommend external database.

  11. What should I do if Collector/Central Server is behind a proxy?
    If the collector is behind a proxy, then enter the proxy settings either in Collector's Installation screen or in the Settings page in web client. If the Central Server is behind the proxy, please NAT the name & https port and provide the NATed values in Collector's Installation screen.

  12. How is the licensing based ?
    The licensing is based on the number of interfaces. It is totally independent of the number of Collectors. The licensing cost is independent of the number of NetFlow collectors that are used.
