Dears, I use netflow to monitor my network. And I want to report about top talker and top connection. By default the result is resume of toptalker on each 15 minutes. How can I have the result of 1 day or 1 week? Thank you very much!

You can change the setting "Period (Minutes)" under Channel settings, but the maximum you can set it to is 1440 (one day).

Hello doquocuy285,

Actually, it is not possible to generate details reports of NetFlow-Sensors with customized time intervals. This is still on the wishlist, as there haven't been further requests to it. I've counted yours, it's still not scheduled for a certain future version. Please bear with us.

If you edit the default settings as suggested by Robert Poljak, please be aware because this will cause higher utilization on your system. If you encounter any performance issues, please roll back to the original settings.

Kind regards, Sven

Dears, By default, PRTG monitor and display all data pass an interface. But I want to display traffic of certain ranges IP ( such as: traffic of only ranges 210.211.0.0/16, 115.110.0.0/16). Can PRTG do that? Thank you very much.

Hello doquocuy285,

you can filter for specific IP ranges in the sensor settings as you can see in the picture below. https://media.paessler.com/kb/2016/netFlow_filter.png

For details, please refer to: NetFlow Filter Rules

Kind regards, Sven
