I have been looking at all of the reports and have yet to find one that I deem appropriate for what I am looking to do.

What I am looking for is a report that can give me the usage of a particular interface over a timeframe (ex. Last Month) with a decent bar graph.

Say that I have an internet connection on a router (10MB) and I would like to see it's usage over the course of a month to see how many times it spiked at 100% usage or something like that.  This would help me see if we are utilizing it at capacity or if I need to look at getting a bigger pipe.

I love the real time graphs that I can assign to an interface so I am thinking of something along that line accept for a controlled time.

If there is another report that I can use to generate this please let me know and I will gladly learn how to use that instead.

Thanks,

Joe
