Webtrends Parameters Sent by the Mobile SDK

Each data collection event sent by the Webtrends Library automatically includes a collection of parameters, described here.

Understanding Webtrends Parameters

Webtrends parameters are the basis of many Webtrends reports. Many of these parameters are populated automatically when you use the methods supported by the Mobile Library. Although you do not need these parameters to implement the Webtrends Mobile Library and instrument your application, they can help you understand the report output generated by the data you collect and to create reports and profiles in Webtrends. For information about how each query parameter is used in Webtrends reporting and the values it supports, see the Query Parameter Reference.

Parameters Sent for Every Event

Every event type sends different values for a set of Webtrends Parameters. These are set either manually (using manual events) or automatically (when using automatics).

In addition to these, all events contain the following Webtrends parameters:
