Netflow version

Hi All,

I've turned on Netflow for my 2 WAN interfaces and pointed to my PRTG collector.  I am having a couple of issues that are making me wonder if I'm using different versions of netflow.

On PRTG, I'm using a Netflow 9 collector but I can't find any documentation indicating the version of netflow used by my Fortigate 100e running version 6.0.4

the specific issues I am seeing: bandwidth utilization does not match the numbers reported on the Fortigate dashboard, not even close.  Also, I have created separate channels for wan1 and wan2, but the bandwidth utilization for those channels also doesn't appear accurate.

thanks in advance.
