When you start the NetFlow Analyzer for the first time, you need to set NetFlow collection port before you can see traffic statistics.
NetFlow collection port is a port on the NetVizura Server (computer on which the NetVizura with NetFlow Analyzer enabled is installed) to which your network devices are exporting the netflow data to. You need to set this port number to match the port number on all your network devices that are exporting netflow data. Default value is 2055.
To set the NetFlow collection port:
Now is a good time to check if the system is working properly.
To do so, follow these steps:
Check the system for warnings or errors.
Click on the Show log arrow (in the bottom right corner). Any warnings or errors will be displayed as well as the instruction to resolve them.
Finally, check if the network statistics are available
Go to TopN > All Exporters tab. Network statistics should be shown on the graphs, this is a verification that the network statistic data has been collected by the NetFlow Collector and that the data has been processed by NetFlow Aggregator.
Note that it may take up to 5 minutes to see traffic from an new exporter. This is the minimum time needed for the application to create the finest sample of traffic statistic
To learn more about system settings in general, go to chapter NetFlow Module Settings. |
All other settings you do not need to set right away. However, you should get back to them once you get to know NetFlow Analyzer a little better and fine-tune the behaviour of your system. |
Besides general network traffic (Exporters, Traffic Patterns and Subnets Sets), it is also possible to setup viewing of the traffic made by organization end users (Windows domain usernames).
To setup this traffic:
Add new End User filter for syslog messages (if needed)
If filter for your Syslog agent is not provided with NetVizura by default, you should create your own in order to successfully authenticate users (map username to an IP address at specific time). It is done at Settings > NetFlow Settings > End Users tab.
