Packets Monitoring graphs are being incorrectly scaled
It looks like the data used for the packets logging is being incorrectly multiplied by 8 as though it is assuming a Bytes value that shouldn't be be applied to PPS.
Whilst running an iperf3 test the monitoring graphs show a pps value of 644.22 kpps but the switch port logs a 5s average of 80600 pps for the same connection.
