The collection levels are:
This choice would be useful if you want to capture information on all routines. Use this option when you know that all the programs called by your application were compiled with either the *PEP, *ENTRYEXIT or *FULL option. Otherwise, if your application calls other programs that are not enabled for performance measurement, the performance tool will charge their use of resources against your application. This would make it difficult for you to determine where resources are actually being used.
Use this option when you think that your application will call other programs that were not compiled with either *PEP, *ENTRYEXIT or *FULL. This option allows the performance tools to distinguish between resources that are used by your application and those used by programs it calls (even if those programs are not enabled for performance measurement). This option is the most expensive but allows for selectively analyzing various programs in an application.
