Hmmm... I don't know of any way of generating a number saying that at
time X virtual host www.foo.com was transmitting Y bits/s directly
from apache.

However, you can simply put TransferLog, ErrorLog and/or CustomLog
directives into each of your <VirtualHost></VirtualHost> sections in
your httpd.conf to generate virtual host specific log files.  Or you
can define a LogFormat that includes the %v directive (see
http://httpd.apache.org/docs/mod/mod_log_config.html), to include the
ServerName into the log data.

Then just use a standard WWW server logfile analysis tool like analog
(http://www.analog.cx/, ports: www/analog) to generate graphs of
traffic vs. time.

	Cheers,
