I was looking at the RRD Graphs and it has some great stats, BUT since my isp has monthly caps, I'm wondering how can I track "per calendar month usage" or "per calendar week usage". My old retired Tomato & DD-WRT & OpenWRT routers all has this feature, but RRD does not show any dates.
Is there a way to make RRD Graph present the bandwidth with dates? Does RRD Graph use RRDTool, if so I believe the latest version has this feature...
I need dates to better gauge my usage, to prevent me from going over the ISP cap & determine whether I need to upgrade or downgrade service based on needed usage.
Any help would be greatly appreciated!
