I have setup sFlow on a FortiGate 60C to send data to PRTG, I am receiving data however the amount of traffic reported is about double what it should be. I have reduced the number of interfaces sampled to just one WAN interface and it is still reporting double the traffic (on average). What can I do about this?

If you use our sFlow Tester, do you get the same results?

I have just tried the sFlow tester. I don't really understand the results it is showing. It is receiving several sFlow's a second though I set the polling-interval to 60 seconds.

The results show a source and destination IP and port, timestamp. Is the number at the end the size of the packet sampled in bytes?

Please forward us the test results to support@paessler.com, so that we can have a look at them. Please refer to this thread, in order to be able to associate the ticket with this case.
