"In-depth"?  How deep would you like to go?  I think there's
enough light to read the documentation down to a depth of
about 30 ft in clear water.  Anything beyond that is too
deep for read.  Be sure to de-compress properly after reading
the docs.

For land-lubbers documentation (not quite as deep), see the
list of links at:

Easy:
   Byte count 5 minutes ago
     minus
   Current byte count
     divided by
   300 seconds.
If the counter wraps, then add 2^32 (for a 32 bit counter)
to the difference in byte counts.

Also see:
   http://faq.mrtg.org/information.html
for how MRTG deals with various types of data.
