The rate on some of the netflow interface charts are higher than the bandwidth configured on the interface. When i check the events log for the device i am seeing any high interface utilization alerts. The "Min/Max/Average bits per second" chart for the interface does not show high utilization.
For example when i look at the top 5 application chart for netflow interface i am seeing a maximum rate of 58 Mbps however the bandwidth on the interface is 20Mb (see attachment "Fig1"). When i select one of the top 5 application on particular the netflow interface (Netflow application page loads) the rate is far below than the max on the netflow interface page.see attachment "Fig2"
It appears that the chart data is accurate when you enter a absolute time period instead of selecting a named time period.
