I want to display most active users list ( for ex last 30 min) accessing sharepoint site .

For that I had parsed the log files created by IIS and got the most active users information…..(Checking for every 30 minutes )

For every portal IIS creating logfile in one folder( W3svc………..) in c:\windows\system32\logfiles\ path

(In IIS )When I select website properties ->properties logfolder name is mentioned

My problem is how to know logfolder name of a portal programitically ( from .aspx page )

Sharepoint also use these logfiles for siteusage …….

How sharepoint knows the log folder path ????????

Where that information is stored?????????????????

If I get that folder name I can go directly there and I can parse log file ………..
