We are using PRTG version 18.104.22.16852 x64 . After I've restarted our Cisco ASA 5515-X software version 9.4(4)17 , no data is showing to on the Netflow sensor.
I used the Netflow Tester but it shows up only Unassigned Flows. I've also doubled checked our ASA's Netflow configuration and it 's proper configured. Any idea what's causing the No data issue?
