I've ended up having to write my own each time I've approached this. It's not hard. Cacti can produce graphs with a 95th percentile line / legend suitable for giving customers an *idea* of what they're going to be billed, but you can't use that directly for billing because the RRD will probably not keep all results for a month. Usually the weekly, monthly, yearly graphs are generated by summarising and averaging out the info from the 5-minute data, so you are losing info and that isn't acceptable when you're billing someone from it. For example, a typical RRD will keep 24 hours of 5 minutes results but prior to that the results will be 30 minute averages of the 5 minute ones. So personally I just make sure I have an RRD or other database that will hold a month of unaltered 5 minute or 1 minute samples and then keep that updated and bill from that. Regards, Andy
