Yes, I have a program that already traverses the logfiles directory and
processes the logfiels to produce just the summary report for each log. What
I asked was, "What is the closest approximation to use to get total users."
I know that this number is not really obtainable but, in my fellow analog
users opinions, I was wondersing what the consensus is for the closest
approximation of total users. I understand that everything is relative.
It looks to me like "Distinct hosts served" may be the closest approximation
to what I would want.
