HMC Performance Dashboard shows different calculated graphs depending if the LPAR is in Shared-Pool and Dedicated Mode

At the moment the HMC Performance Dashboard is using a different calculation method - depending on the LPAR using Shared-Pool or Dedicated-Donating Mode - to display the CPU utilization graph without any hint of these differences.

Both graphs are useful. The problem is the different calculation depending on LPAR mode without proper naming and differentiation in the HMC Performance Dashboard.

Therefor please make both graphs available in Shared-Pool and Dedicated Mode so customers can use them according to their use-case. Please provide clear naming and documentation for both graphs so customer can better understand which metrics the graphs are referring to.

    Hi Peter,

    To clarify further on the enhancement, there are 2 aspects mentioned in this request

    1. Difference between utilization computation for dedicated donate & Shared processor partitions - this is being fixed as a defect in the upcoming updates for HMC V10 and HMC V9. The change is to show what might be actual capacity available after subtracting the idle cycles for both dedicated donate and shared proc partitions.
    2. Show 2 different views in HMC PCM dashboard one for Physical Processor time consumed by the partitions and another for what might be actual capacity available after subtracting the idle cycles and ability to switch between views -- this is being considered as a future enhancement.
