SAS page
tag logs are those logs collected by a clickstream collection server
(Apache HTTP server with the SAS Data Surveyor for Clickstream Data
Mid-Tier Components installed). The content of these logs is generated
by JavaScript page code that is inserted into the pages of interest
on a Web site. SAS page tag log files are created in a custom log
format supporting richer information than the information contained
in a standard Web log.
When initially
deploying the SAS Data Surveyor for Clickstream Data for a site, you
will likely already have standard Web log data. As you incorporate
the SAS page tag into your Web sites, you begin collecting richer
data.
Identifying
and understanding the data source that needs to be processed helps
you to decide which tutorial or template jobs to select in the chapters
to come. If you intend to collect SAS page tag data, then you need
to perform extra tasks for inserting JavaScript page tag code into
your Web pages. You also need to prepare one or more clickstream collection
servers. (These tasks are described in Chapter 5: Preparing SAS Page
Tag Data.) You do not have to perform these tasks if your data source
is a standard Web log.
