Network Traffic Analysis
What is the best option for analyzing network usage from a Cisco 3560 which does not support netflow? I've tried different tools from solarwinds. Wireshark just gives me tons of packet information. I need something simple that will show me what percentage of my bandwidth is being used by what service/port.

For one machine, DU Meter (dumeter.com) does that. The new version (7) has a networking reporting tool. It is for one computer (in terms of traffic) but is inexpensive and very nicely summarized. It might give you some clues.

I need it for the entire network. I have a computer with a connection to a mirrored port.
Solar Winds does that but entire network tools that summarize well are expensive, so be ready for that. It does not come cheap.
A good option for analyzing network usage is OpManager

nagios, naemon, prtg, mrtg, netflow
Observium is also very good

These will all break down the traffic by type? What is like to find out is how much bandwidth is being consumed by certain applications such as Netflix, YouTube, streaming radio, etc.
You will then need data mining tool on servers using the traffic so you can do analysis
From the firewall you should be able to get all this information
