If your log file has requests from several virtual domains, but there
is nothing in the log file to distinguish them, there is no way for
Analog to do that either.

You need to change your log file format (in OmniHTTPD) to include the
virtual domain in a field on each line of the log.

Then you can use Analog's LOGFORMAT command to create a custome log
file format for Analog using the '%v" to indicate where the vitual
domain field is. Analog can then generate the Virtual Hosts report
which will give you a comparision of each site. See
http://analog.cx/docs/logfmt.html.

To generate a report for all hosts and one for each host, you will
have to run Analog once for each report you run. Use the VHOSTINCLUDE
command to limit the report to a particular virtual host. See
http://analog.cx/docs/include.html.
