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, videos & playlista on: nmon and njmon Beginner and Advanced, Power10 Best Performance, Power10 server introduction, fly past and fast facts, HMC Enhanced+ GUI, PowerVC, and Shared Storage Pool.
Other sources of good information for POWER processor based computers is the two online Virtual User Groups, which have monthly Webinars on many topics
