You select any of them, configure its specifics properties and add it to the report.
Almost every widget shares some common characteristics:
Title / Add to TOCTable of Contents
Every widget will be presented as a page of the report.
Title lets you provide a string (a title) that will identify the report page.
You will then decide either this title appears or not in the Table of Contents of the report.
Depending on the widget, you can select additional properties to decide the degree of detailed information that will be printed.
These properties will be included in final reports as the next image shows.
Summary widgets allow to represent global (aggregated) information about application metrics.
