Unfortunately, the RMF Crypto Hardware Activity report will be focused on the utilization of the crypto cards (the Crypto Express cards), not the CPACF. The CPACF simply provides some additional instructions that perform crypto operations (Cipher Message, Compute Message Digest, etc.). And just as you can't break out the CPU utilization of a single Move Character or Shift Logical instruction, you can't break out the CPU utilization of these instructions either.
That said, starting with the z10 machines we did make the CPU Measurement Facility available. This facility gives you the ability to 'count' instructions and that includes many of the crypto instructions. John Burg has done presentations on the use of the Measurement Facility at Share and zExpo/zTech University. You can access at least one version of the presentation on the IBM ATS TechDocs website (http://www.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/TC000005). I should point out that the Measurement Facility captures data at the LPAR level. In contrast, the RMF Crypto Hardware Activity report is for the entire CEC, and thus the entire crypto card. The point being that you have to be careful how you interpret the reports (both of them). John has experimented with using the data from the counters to calculate the CPU consumption of the various instructions. If nothing else, you should probably monitor these counters (at least for the crypto instructions) so you can develop trend lines and monitor the use of crypto at that level.
