NetVizura NetFlow - Raw Data Table (flow records)


Clicking on Names button provides IP address resolution. If you move your mouse cursor over specific IP address you can see WhoIs information about that host.


On this page:































In order to enable IP address resolution, your NetVizura server should have local or remote communication with DNS server (for Hostname) and Internet access (for Whois information).

Exporting Raw Data  

Raw Data table can be exported as a CSV file in order to present captured netflow records as a report to a third party or for further analysis.

To export Raw Data, click on the the Export button in the upper right corner of the Raw Data Table.

NetVizura NF - Raw Data Export


Depending on the amount of data, export can last a couple of minutes

Depending on your browser settings, browser may ask you were to save the file or it will save the file to a default folder (usually Downloads folder). Some spreadsheet software may ask you which separator to use when opening the file - select Comma.





Grouping, filtering and sorting the raw data table will affect the CSV as well. This will also make a CSV file much smaller.
