Partition Data Section for PR/SM environments

The Partition Data Section shows logical and physical processor utilization by partition.

The partitions are grouped by the type of physical processors that they use: standard CP, ICF (Internal Coupling Facility), IFL(Integrated Facility for Linux), zAAP (zSeries Application Assist Processor), zIIP (zSeries Integrated Information Processor), and so on.

CPU-Utilization-Report

A partition having multiple processor types appears multiple times, once for each processor type that it has. The last partition reported for each processor type is always PHYSICAL. PHYSICAL is the PR/SM overhead that cannot be attributed to any individual partition.

Important

If a partition has a mixture of shared and dedicated processors, in addition to an existing line for each partition, two additional lines show data similar to the partition level line but separately for shared and dedicated processors.

An example of the Partition Data Section of the CPU Utilization Report for a PR/SM environment is shown in the following figure:

Partition Data Section field descriptions

The table below describes each field in the Partition Data section of the CPU Utilization Report:

Field	Description
MVS PARTITION NAME	Name of the home partition
NO OF PARTITIONS	Number of PR/SM partitions that are defined for this processor complex
CAPPING	Capping options that are active on the home partition INITIAL—whether initial capping is active LPAR HW—whether LPAR absolute capping is active GROUP HW—whether hardware group absolute capping is active ABS MSU—whether absolute MSU capping is active
IMAGE CAPACITY	CPU capacity in millions of service units (MSU) per hour
DISPATCH INTERVAL	Time slice interval in milliseconds The word DYNAMIC indicates a variable time slice interval.
CAPACITY GROUP NAME	Name of the LPAR capacity group if the home partition belongs to one
CAPACITY GROUP LIMIT	MSU limit for the capacity group Warning Important An asterisk (*) immediately following the value in this field indicates that the partition was a member of the capacity group for less than four hours, with respect to the end of the interval. That is, a complete four-hour history of MSU consumption was not available to WLM, and the group limit could not be guaranteed.
PHYSICAL PROCESSORS	Number of physical processors in this processor complex If processor types are identified by hardware (CP, ICF, IFL, ...), the next lines list the \| number of physical processors of each type.
CAPACITY AVAILABLE	Presents the capacity that is available to the partition during the reporting interval This field represents the long-term average of CPU service in MSUs per hour, which would have been allowed by the capacity group limit but was not used by its members. If the value shown is negative, the group is capped.
PARTITION	Up to eight-character partition name Warning Important Partition PHYSICAL, if present, is actually not a logical partition; rather, it is a placeholder for PR/SM overhead that cannot be attributed to any individual partition.
STATUS	State of the partition, either ACTIVE or INACTIVE, at the end of the report interval If the partition was inactive at the end of the report interval but had been previously active, the rest of the line is blank except for the AVG % DISPATCHED columns.
WEIGHT	Average weight of the partition; possible values are: nnn —all logical processors not dedicated DED—all logical processors dedicated DNE—a mixture of dedicated and nondedicated processors; nondedicated processors have equal weights DNN—a mixture of dedicated and nondedicated processors; nondedicated processors do not have equal weights TOTAL—sum of the weights of the shared LPARS
BT	Boost type that was active for the interval Possible values for this field are as follows: Z—zIIP Boost S—Speed Boost — N/A
LOG PRCR	CNT—if partition is managed by WLM, the average number of online processors; if partition is not managed, the number of logical processors defined for the partition TYPE —processor types displayed if identified by hardware Warning Important zAAPs are displayed as ZAAP (on IBM z9 or later CPUs) or ICF (on pre-z9 CPUs). zIIPs are displayed as ZIIP.
MSU	The following columns are applicable only for standard CPs: DEF— defined capacity of the partition in MSU/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 defined capacity. Warning Important If an asterisk (*) immediately follows the value in this field, it indicates that the defined capacity changed during the reporting interval. USED—MSU per hour actually used %DEF—percentage of used MSU/hour over defined capacity Three dashes (---) appear if the partition does not have defined capacity.
CAPPING	%WLM—percentage of time that WLM capped the partition Three dashes (---) appear if the partition does not have defined capacity. Warning Important This column is applicable only for standard CPs. DEF: YES—indicates that hard cap was specified for the partition; NO indicates that the partition was not hard capped I—1st position - whether initial capping is active L—2nd position - whether LPAR absolute capping is active G—3rd position - whether hardware group absolute capping is active nnn—LPAR absolute capping limit Warning Important If LPAR absolute capping is the only form of capping active on the partition (-L-), then the capping limit value is displayed in number of CPUs.
%DISP LOG	TOTAL—percentage of dispatch time over online time, for all logical processors of an LPAR The dispatch time includes LPAR management time. EFFTV—percentage of effective dispatch time over online time, for all logical processors of an LPAR The effective dispatch time is the total dispatch time minus PR/SM management time.
%DISP PHY	EFFTV—percentage of effective dispatch time of all logical processors of an LPAR over online time of all physical processors The effective dispatch time is the total dispatch time minus PR/SM management time. OVH—percentage of PR/SM management time of all logical processors of an LPAR over online time of all physical processors The PR/SM management time is commonly referred to as PR/SM overhead. TOTAL—percentage of dispatch time of all logical processors of an LPAR over online time of all physical processors The dispatch time includes PR/SM management time. Warning Important The TOTAL column is the sum of the EFFTV and OVH columns.
CPU DISPATCH PERCENT	A graphic representation of the logical and physical processor dispatched percentage, where L shows the logical value and P shows the physical value
