[Ntop] Using ntop to Track Traffic Over an Extended Period, sticky-hosts

What is "ntop host name"? Ntop "sniffs" name res requests, but I don't think it looks in http headers for url connects, does it?
If you have the right detail enabled in the rrd plugin, there's a basic gui graph function in ntop to get at said data. Perhaps if you compile with sql it will give you more options?

Gary, basically bytesSent and bytesRcvd accumulated over a period of at least a week. Also the ntop hostname, which for HTTP sites is often more useful than the nslookup information. With the hostname I can consolidate traffic from sites that show up with different IPs.
I see where the RRD data is being stored. I have read Burton Strauss' 2003 paper but am not much further in figuring out how to get useful summary information out of the XML dump. I think I need to look at the AVERAGE (300 seconds) section, convert bits/second into bytes and sum across the period I am interested in. I assume the other AVERAGE seconds are 'rollups' of the data.
