Hey guys,

We have a 100MB fiber line coming in, and an ASA5515 firewall. Looking at our Outside interface on our ASA through ASDM, i see that sometimes it spikes to 80-90MB. How can i figure which user(s) are using the most bandwidth and where they are going to?

In ASDM on the home monitoring window. You can select top usage. Looks something like this:

Not sure what you mean by that, but it's real-time. I had a client complaining that internet access would slow down periodically. Next time they called, I checked the graph, identified the address and informed the IT manager that user at IP address x.x.x. was receiving large amounts of data from Netflix using 75% of the bandwidth.

Problem solved... or at least identifiedSource.jpg.
