Nigel also called "Mr nmon" due to his Twitter handle @mr_nmon as the developer of nmon & njmon programs among other performance-related tools for AIX, Linux on Power and Linux generally.
Note: I cover many POWER and AIX topics in my ~210 videos:  www.youtube.com/nigelargriffiths
For example, single video & video playlist on: nmon and njmon Beginner and Advanced, the new IC922 POWER9 server, POWER9 Best Performance, POWER9 server introduction, fly past and fast facts, HMC Enhanced+ GUI, PowerVC, and Shared Storage Pool.
Another source of good material for POWER base computing is the two online Virtual User Groups, which have monthly Webinars or many topics
