In accordance to let capman_da & ibmvm_rest collect maximum amount of configuration data:
It is for
Number_of_CPU_Cores Total_Memory hardware_family (<-not working for me or I don't know how to enable) power_state
Physical_Host Partition_Name Partition_Type partition_mode Maximum_Virtual_CPUs Minimum_Virtual_CPUs Maximum_Memory Minimum_Memory Minimum_Capacity Maximum_Capacity power_state Active_Virtual_CPUs Online_Memory
you need to enable appropriate monitors at ibmvm_rest via Infrastructure Manager GUI. Insert attached template into ibmvm_rest.cfg section <template>, restart probe and apply by drag&drop included monitors to Auto Cofigurations under each HMC.
You don't need to enable QOS or alarms. Monitor need be just enabled.
