Use ISA 2004 to monitor usage

I have installed ISA 2004 for the first time, have just begun using it.  I would like to monitor how much bandwidth we use up and down to try to determine if it's justified to increase the speed of our internet connection.  Can someone run through the steps to create a report that would show us this information?

Couple of steps first....

Are you using isa as a proxy or as a firewall?
Part of the ISA installation includes additional performance counters. Click on start - programs - ISA Server -ISA Server Performance Monitor
In here you will see all of the standard counters already added to review ISA's traffic and process activity.

If you want to 'see' activity,
Open the isa gui, select monitoring - reports.
Sekect create a report, do NOT click on generate a report.
Click add
Give it a name & fill in the criteria you want etc then save.
Click on create a report again and you will see your previous report template. Highlight it and this time you will see the 'run now' button is available. this includes the traffic utilisation for the period. The report will also run automatically as per the times you entered...

If you want real-time viewing, don't use ISA at all for the monitoring of the bandwidth. Something like PRTG will be ideal where you can point it at an interface on your external router or switch. Will be much more accurate, a great utility and fine graphs etc. and the two-interface version can be downloaded directly.

I do not think it can seperate the normal traffic from the voice traffic as it is all just traffic passing through the interface(s) being monitored. We can monitor ours as we use different pipes for voice as those for data. Same links but different channels and as each has its own interface we can select them independently.
