Like most beginner's questions, the answer is a bit complicated.

Sync speed and noise margin figures can be read off the ADSL router,
by any of the methods which it supports, at any time.
Real upload and download speeds aren't evident from the router: you
have to pass some traffic. Typically it's done by one of the
browser-invoked speed testers, e.g the one at ADSLguide, or the ISP
may have one of their own. Some folks run their favourite FTP
application, or a browser download, if they don't trust the speed
testers. You wouldn't do that continually - only now and again.

Routers typically support several methods of reading out their
statistics. Mine has a web interface, telnet, or snmp. Your choice,
really.
There are applications that you can set up, which would read out the
values at appropriate intervals and plot them on pretty graphs.
Or one could write a little script that did wget to the appropriate
web page on a schedule, and append the answer to a log file.
Lots of different ways. Hope that's vaguely useful. What have you
actually got? Have you seen this page?
