Capacity Group Section
The CPU Utilization Report provides a Capacity Group Section that lists each LPAR capacity group with its respective capacity limit, names the LPARs making up the group, and lists certain attributes and counts for the LPARs.
An example of the Capacity Group Section of the CPU Utilization Report is shown in the following figure.

Capacity Group Section field descriptions
The table below describes each field in the Capacity Group Section of the CPU Utilization Report.
Field | Description | |
|---|---|---|
CAPACITY GROUP | name of the LPAR capacity group | |
CAPACITY LIMIT | MSU limit for the LPAR capacity group | |
PARTITION NAME | name of the LPAR, a member of the capacity group | |
SYSTEM NAME | MVS system name | |
MSU | DEF | defined capacity of the partition, expressed as MSU per hour Defined capacity can be specified for a partition running z/OS on a z900 machine. Three dashes (---) appear if the partition does not have a defined capacity specified. |
USED | MSU per hour that was actually used | |
% DEF | percentage of defined capacity for this partition that was actually used This field is calculated as follows: (MSU_USED * 100) / MSU_DEF Three dashes (---) appear if the partition does not have a defined capacity specified, and this calculation is not performed. | |
WGT | average weight that is assigned to this partition Possible values for this field are as follows: | |
nnn | all logical processors are not dedicated and have the same weight of nnn | |
DED | all logical processors are dedicated | |
DNE | a combination of dedicated and nondedicated processors; nondedicated processors have equal weights | |
DNN | a combination of dedicated and nondedicated processors; nondedicated processors do not have equal weights | |
CAPPING | HARD | capping option specified for the partition, YES or NO
|
WLM% | percentage of time that WLM considers capping the partition usage of the processor resources | |
ACT% | percentage of time when capping actually limited the usage of processor resources for the partition | |
GUARANTEED | MINIMUM | guaranteed MSU share that the LPAR gets, if necessary, when other LPAR group members are competing with this LPAR because the group is running at the MSU limit If absolute capping is turned on for all LPARs in the group, this field is calculated as follows: MIN((Initial WGT * Group_Capacity_Limit / SUM(Initital WGT_of_All_LPARs_in_Group)),Defined_Capacity) Otherwise, this field is calculated as follows: MIN((Current WGT * Group_Capacity_Limit / SUM(Current WGT_of_All_LPARs_in_Group)),Defined_Capacity) |
MAXIMUM | maximum MSU share that an LPAR can get when other LPAR group members are not competing with this LPAR because the group is running below the MSU limit This field is calculated as follows: MIN(Defined_Capacity, Group_Capacity_Limit) | |
SUMMARY | MSU DEF | total of the MSU capacity limits for all partitions in the capacity group |
MSU USED | total actual MSU consumption by all partitions in the capacity group | |
MSU %DEF | percent of the total MSU-defined capacity that was consumed by all partitions in the capacity group | |
TOTAL WGT | total weighting of the shared-processor resources of all partitions in the capacity group | |
