Berigan, Matthew ([EMAIL PROTECTED]):
Hi!
I'm finally past bad log data and I think that I'm getting inconsistencies
between WebTrends and Analog that can't be explained by INCLUDES or
EXCLUDES.
First, here's the summary results:

Most everything (A-D)appears to be close enough that I don't even consider
it worthy of question.
Well, to answer anyway, WT counts some redirects as successful
requests that Analog does not.
Item E, however, bugs me. Can anybody guess why
Distinct Hosts [Analog] and User Sessions [WT] should be so different?
Because they are different quantities.
I think this is supposed to be the same data and my assumption is
that it is the number of distinct IP addresses listed in the log (I
suppose I could count those (ck!!)).
Sessions is something that WT estimates (and by most accounts very
poorly.) It does not represent the number of distinct IP addresses in
the logs. It is meant to represent the number of distinct user
sessions. Read http://www.analog.cx/docs/webworks.html as to why
that's not easily counted and why Analog does not do it.
