Upsetting the Old School with NetFlow Innovation in Application Performance Monitoring

EMA's new report on Application-Aware Network Performance Management (ANPM) highlights a few newcomers to the space.

A note on double counting SPAN port traffic on the Cat6k

The Flow Table screenshot below shows the problem in action... At first I thought it was an issue with the retransmission detection algorithm, but on further inspection realized the issue was a misconfiguration in a Cisco SPAN session's directionality. If we log into the FlowSensor that was seeing the retranmissions and run a tcpdump we… READ MORE
