I'd probably suggest vnstat or something similar as a log of activity and speed rating at your endhttp://humdi.net/vnstat/

You will only really be able to see your side (client connection ) directly
--there are some ISP bandwidth traffic monitors available (mainly for ISPs'); which is probably what they match their rating against, it will just be an average rate, and as we know average doesn't mean much with large-low user spreads; it distorts the rating speed, so that it will look better than it really is..http://www.ispgeeks.com/wild/--you can either get a speed test when it is slow for you or get an overall rating by logging the connections with any/.some of the tools linked..
The standard tools are mrtg and nagios/nmaphttp://oss.oetiker.ch/mrtg/http://www.nagios.org/http://www.netmrg.net/http://www.ntop.org/overview.html
Others are available, which probably use parts of mrtg (for graphs)http://bandwidthd.sourceforge.net/http://cacti.net/http://etherape.sourceforge.net/
Or just leave an IP monitor runninghttp://humdi.net/vnstat/http://www.ex-parrot.com/pdw/iftop/http://robert.cheramy.net/ipfm/http://ibmonitor.sourceforge.net/
