Netflow Sensor - Connection-Report for 1 Day




I need a list of all the connections of a day reported by the Netflow sensor.

When I open the Netflow Sensor -> Top-Connections -> I can see a list of connections containing the following information: Sender-IP, Sender-Port, Destination-IP, Destination-Port, Protocol, Bytes...

However, only for 15 minutes at a time.

I need a list with of this information for the periode of one day. How can I get this information? When I build a report, I can only get the information about the protocol usage. But not about the single connections.

Hello Udo,

you can adjust the time interval for the Toplist by clicking the gears on the bottom of the of the specific overview.
Here you could adjust the time interval up to 1440 Minutes (1 day), even though it is possible we wouldn't recommend it in every day use.
This is because the top list will only be generated after the set time interval has been passed, therefore a more granular time interval is advised.
How the Toplist work and what all the options do, you can read this up in our manual.

If you run into the error "Data incomplete, memory limit was exceeded" then the time interval is too large for the memory that is allocated to the Toplist. The maximum size allocatable is 100 MB and is also set in the settings for each overview.
If this continues to happen even with the maximum of 100 MB please lower the time interval.

I'm afraid that PRTG does not support reporting for flow information. If you want more Insights in your Netflow statistics than PRTG alone can offer, we would recommend a solution from our Uptime Alliance Partner Plixer.

Kind regards,
Johannes Beyerlein, Technical Support Team
