Regardless of how the debugging information is accessed (through any of the options just listed) you’ll have access to the same information:
Execution time, so you can locate poorly performing code.
Database activity, so you can determine exactly what was passed to the database drivers (post any dynamic processing) and what was returned.
Tracing information (explained below).
Variables and their values.
As you move from page to page within your application, the debug output will provide insight into what’s actually going on within your code.
The exact information displayed in debug output is managed by options in the ColdFusion Administrator.
