I am looking for services or tools that allow me to monitor our web
servers traffic on our site (we are an ASP). We are running W2K,IIS
and MS Site server. The user traffic information is already in the log
files but it is very cumbersome to generate and read the reports.

I am looking for services such as webstat.com - but it is quite costly
and also it requires us to insert code on every page (I will do that
if I have to).

I hope someone could point me to the right direction. I expect the
answer to be e.g.
- xxxx.com provides the services and is much cheaper or
- you can use xxx software (or service) which costs yyy which can read
the data from your log files, or
- etc.

you can try out MRTG, this programcan be used on unix and windows
based system. many people use it the link is

MRTG seems to provide only the chart for network traffic - correct me
if I am wrong.

What I need are pageview for monitored pages, who/from where access
it, etc.
