I discoverd PRTG a few weeks ago and found it played will with ePMP1000 so I've set up some monitoring...but there's something I can't figure out:
While monitoring the ethernet port of any SM, it is constantly showing ~350kbits/second of usage. When I set up a test link I found that, even when I'm not pushing data through the connection, it still shows ~350kbits/second of data - Traffic out of the ethernet port.
The thing is, even if I have it plugged into a switch, with nothing else plugged in, it shows the same data out from the ethernet port.
So I did some math and found that ~350kbits/second over a month is a LOT of data, and it's totally messing with my ability to see how much data my clients are actaully using.
I used wireshark to see what was going on and it showed just a few discovery packets, nothing to justify the displayed usage. Can anyone enlighten me on what is going on and maybe how can I correct or compensate for it?
