Andrews & Arnold have different usage rates for peak vs. off-peak times.

Since I started working from home, my Internet usage during the day has sky-rocketed. I would, therefore, like to generate some pretty charts / reports that show me which HTTP / SSH / whatever connections are contributing the most to my usage total, so that I can better understand my usage.

My router is running OpenWRT, so all of that information should be available somewhere, but I'm looking for software recommendations.

Thoughts?
