Hi Suzanne, hopefully I am understanding your question properly. 

Performance Analytics (PA) is available included with certain application bundles or across the whole platform (license wise).  In terms of what applications PA supports, as a native part of the platform it can be leveraged on almost any data contained in the platform.  

If your question is about the differences in our products, this page might be a good starting point for understanding which applications are included in each suite (For example, what is in ITBM): https://www.servicenow.com/products-by-category.html

Hopefully that helps?
