Webtrends Analytics 9 Adminstration Guide, November 2012
Webtrends Analytics Reports data captures provide the most complete data possible from Webtrends Analytics 9. To ensure efficient reporting and surface the data of greatest interest, Webtrends reports are limited so that they include a large portion of the analysis data.
Because very large web sites can generate millions of unique URLs, for example, the processing time required to transform all these URLs can be prohibitive. Data captures make analyzed data available before it is prepared for reports, enabling you to work with a potentially much larger and more complete data set.
Analytics Report data captures save this more complete data in CSV format after each analysis runs, and make the data available on a Webtrends SFTP server. You can then download this more complete data and import it into your own storage and reporting solutions.
