It’s important to know a CPU capacity used by a system. In IBM i world, we have a licpgm – 5761PT1 Performance tools. But what if you run other OS’s than IBM i, on the same POWER box. Or you run LPARs in different shared processor pools ? The most efficient might be tracking CPU cycles dispatched by the POWER Hypervisor. In this post I show you, how to interpret performance data collected by a HMC, and how to allow IBM i collects and display dispatched CPU cycles.
