Re: Usage Statistics
In our case, our current statistics for locally maintained databases count the number of logins. This of course is only a rough approximation of the number of users, since even with a timeout we often have several users at a public station using the same session. With our web server we haven't come up with an equivalent to a "session", and the one set of statistics we got from an online web vendor was a difficult to read mass of data much like our web statistics. What matters most to us in interpreting the data is consistency. I'd like the same data calculated each month, and I'd like it to match our old figures as much as possible. To most closely approximate the old "session" I'd like to have the number of users who use the resource (retrieve an article or articles) with the understanding that the same user coming back over an hour later would be counted as a new "session". Usually the online providers only have a computer IP number, not a name, for the user, but that parallels our experience with our public terminals that have no password. Of course validation by IP number and domain name is also a great problem for us, since users of our local data bases come in from a great variety of IP numbers and domain names. If we can arrange a different validation method with the vendors cooperation, we'll also have much better ways to count the sessions ourselves.
