Also consider using SVC 109, which calls another module based on the value R15. Like 'direct' SVCs, numbers 200 - 255 are reserved for customer use. One advantage of this SVC is that you're less likely to bump into another exploiter because the 109 mechanism is relatively new(er).
I assume you have studied "MVS Diagnosis: Reference" , GA22-7588 in my z/OS 1.8 library.

Several tools have been mentioned, but they all have the limitation that they can only show you what is currently in effect - on the system looked at.
