To assess the performance affect or attributes of a particular function in the program that you are monitoring, use the Health Center to remove all currently analyzed data from the views.
The Health Center provides information about a monitored application. To concentrate on specific details, you can isolate some data. For example, if you want to assess the most active method during a file load operation, you can isolate the data recorded for program actions that take place when you use the application GUI to load a file
Health Center provides this ability through a menu option Data and Reset data, duplicated on the toolbar. Reset data immediately deletes the data stored in the data model in all views. You see data collected only after the time that you start the Reset data function.
