Using the CPU Processor Activity Instrumentation Facility
The PAI facility was introduced with IBM®
z16® and IBM® LinuxONE Emperor 4.
Use the PAI facility to obtain counter data, by CPU, for specific instructions.
The PAI facility provides the following counter sets:
- Cryptography counters, see Cryptographic counters and events.
- Analytics counters, see Analytic counters and events.
You can use the counters in counting mode or in sampling mode.
- For counting mode, see Collecting data in counting mode.
- For sampling mode, see pai - Record and report PAI counters.
