Analyzing Log Files

Applies To: Windows Server 2003, Windows Server 2003 with SP1

Internet Information Services (IIS) 6.0 offers a number of ways to record the activity of your Web sites, File Transfer Protocol (FTP) sites, Network News Transfer Protocol (NNTP) service, and Simple Mail Transfer Protocol (SMTP) service and allows you to choose the log file format that works best for your environment. IIS logging is designed to be more detailed than the event logging or performance monitoring features of the Microsoft® Windows®  Server 2003, Standard Edition, Windows®  Server 2003, Enterprise Edition, and Windows® Server 2003, Datacenter Edition, operating systems. IIS log files can include information such as who has visited your site, what was viewed, and when the information was last viewed. You can monitor attempts to access your sites, virtual folders, or files and determine whether attempts were made to read or write to your files. IIS log file formats allow you to record events independently for any site, virtual folder, or file.
