How can I view traffic with the parameters "Source IP, Source Port, Destination IP, Destination Port



I'm using a trial version PRTG ( I added a network device (router Cisco) and created a netflow v9 sensor. The "Top Connections" dashboard show a traffic with parameters "Source IP, Source Port, Destination IP, Destination Port" but only for fifteen-minute intervals. Can i see a traffic with parameters "Source IP, Source Port, Destination IP, Destination Port" for different time intervals? For example today i need report about five-minute interval and tomorrow about a two-hour.

Or is there another way?

Hello there,

By default toplists are drilled down to "Top 15", this can be changed in the settings of the toplist (--> gearwheel icon next to each toplist on "Overview" tab), but don't overdo it, because depending on how many flow sensors you have running and how much data is coming in, you might run into memory issues (probe service that processes the flows is a 32bit service).

Kind regards,

Thanks for you reply. And i can monitor only one time interval? if i need report about other time interval, i must manually calculate this (sum or divide)?

You could as well create an additional NetFlow sensor that is configured differently regarding the amount of toplist entries.
