Netflow 2 hour graph shows higher bandwidth than possible




I am collecting netflow information. When i look at the 2 hour graph for any of our sites the reported stats always show higher than the bandwidth configured on the interface.

for example one of the graphs averages 120000kbits/s yet the interface is configured for 100MB. Am i reading the graph incorrectly?

Regards Ian

Pretty sure both values are in BITs - right?

I see the same thing - I personally always explained it to my self with okay - this is telling me about sessions that happened, it is not a accurate traffic for this one point in time picture. Netflow shows you sessions, it at one point gives you data about how much was send/received on this session - this is not a load on the interface rather then a load-indicator for various traffic groups (web/media/etc.) and who talked with whom.

If you want to see the load on the interface, you would look at a specific monitor for the interface.

But out of curiosity, let's see if my initial assumption is correct and what the support has to say about it :-)

To allow us a better overview of what is going on, please send us the following screenshots of the affected sensor (out of the PRTG AJAX Webinterface), with an email and referring to this KB-Thread please:

  • the "Overview" tab,
  • the "Log" tab,
  • the "Settings" tab (multiple screenshots if necessary to cover all options).

Please make sure the screenshots show the entire user interface, and aren't cropped.

Best regards.
