tracking down excessive bandwidth usage




I have a content packet sniffer in place trying to track down excessive bandwidth usage going to my provider. I've set up an exclude filter of sourceip[] and destinationip[] so I don't get intra-lan ip traffic.

So far the two protocol classifications using the most bandwidth are the www and 'various' groups. How do I determine which URLs are in the www group and a breakdown of the protocols in the various classification? Would also like to see which IP addresses they're going to/coming from as well.

Dear Ben,

have you checked the TopLists of the Packet Sniffer Sensor yet?

Best regards.

I have; the results show high 'other' usage or high web traffic. Knowing what constitutes 'other' is a mystery for me. As well as determining within the web traffic, which intranet servers are generating it, and within those, which sites. I understand there is no site (ie domain) level tracking mechanism available.

How would I break down the other category?

Where exactly do you see the "Other"-entry? In the sensor results? Or in the Toplists. Because that would be two different things. Other in Toplists means a summery beyond the limit of entries for a toplist: What does the 'other'-entry in my TopConnections/TopTalkers mean?
Whereas Other in the sensor results itself means traffic type(s) unknown to PRTG.
