Import Web Log File Data

The Web server log import DTS task imports Web log file data generated by your Web site into the Data Warehouse.

The configuration of your application and Web servers will affect the log file data imported during the Web server log import DTS task. You use the Web server log import DTS task to specify which log files to import into the Data Warehouse, and where they are located. Web server log files stores data that is obtained when users visit your site and click links to site pages. The data includes the length of time a user spent visiting your site, referring site, ad clicks, ad reach, click frequency, and the path the user takes through the site, including entry and exit pages.

Imported Data

Use the Import Web Server Logs Dialog Box to specify basic and advanced properties governing the Web server log import DTS task. You specify what log files to import and where they are located.

The following tables list the columns extracted from the W3C log file, the transformation made, and the tables the data is saved to in the Data Warehouse.

Most Data Warehouse tables also contain a SiteName column. This column, just as TableID and TableInternalFlag, is also not listed in the tables in the following sections because the SiteName is always extracted from the same location for all DTS tasks.
