I've configured a PRTG NetFlow v9 monitor to generate a list of Top Talkers over a 24 hour period on a Cisco 3850. Its working brilliantly in PRTG and is generating beautiful charts and tables. However, due to the ebb and flow of traffic flows, I need to be able to capture over longer period. The max in PRTG appears to be 24 hour (1440 minutes) so I started looking at the API feature in some hope I'll be able to collect and later render in Python:
But I always get the response "Not enough monitoring data". Any suggestions?
