Summary Section field descriptions

The table below describes each field in the Summary Section of the CPU Utilization Report.

Field

Description

CPU FAMILY

CPU family or machine type

HARDWARE MODEL

Hardware model identifier

This field applies to IBM z/OS version 1.7 and later. For an identifier formatted as xyy, yy is the maximum number of physical processors of all types (standard CP, zAAP, and so on) that can be installed on the central electronics complex (CEC).

HARDWARE CAPACITY

CPC model capacity rating

NOMINAL MODEL

CPC model identifier

For an identifier formatted as xyy, yy is the number of standard CPs on the CEC; therefore, the identifier indicates the capacity of the CEC.

NOMINAL CAPACITY

Model temporary capacity rating

HIPERDISPATCH ENABLED

Indicates whether the HiperDispatch mode is enabled (YES), disabled (NO), or not applicable (---)

CHANGE REASON

The reason for a capacity change:

  • NONE: The CPC is running at normal capacity (100% effective capacity). No capacity change occurred.
  • POWERSAVE: The CPC is running in a power-saving mode. The user initiated the capacity change.
  • MACHINE: The CPC is running in cycle-steering mode. The system initiated the capacity change.
  • N/A: The system did not report a reason for the capacity change.

BOOST CLASS/TYPE

(PTF BQM1631 applied)

Boost class and type that was active for the interval

Possible values for boost type:

  • Z—zIIP Boost
  • S—Speed Boost
  • B—Both zIIP Boost and Speed Boost
  • N —None of the above boost types

Possible values for boost class:

  • SHDN—Shut Down Boost
  • IPL—IPL Boost
  • NONE—None of the above classes, or no boost type is active

A CPU QUEUE EXISTED

Percentage of time that address spaces were found dispatchable and waiting for CPU

AVERAGE QUEUE DEPTH

Average number of dispatchable address spaces that were waiting for CPU

MAXIMUM QUEUE SIZE

Maximum number of dispatchable address spaces that were waiting for CPU

LPAR CPU UTILIZATION PERCENTAGE

LPAR CPU busy percentage of standard CPs, zAAPs, and zIIPs

The formula is the percentage of busy time / online time.

MVS CPU UTILIZATION PERCENTAGE

MVS CPU busy percentage of standard CPs, zAAPs, and zIIPs

The formula is as follows:

  • LPAR mode: (online time - wait time - parked time) / (online time - parked time)
  • Under VM: (interval - wait time) / interval

PROC SHARE (% OF PHYSICAL PROC)

Percentage of a physical processor that this logical partition is guaranteed

This value can exceed 100% and is calculated based upon the weight of the logical partition.

CPU UTILIZATION DISTRIBUTION

Distribution of CPU busy time among batch, TSO, and Started Task address spaces, totaling 100%

BLOCKED WORKLOAD ANALYSIS 1

OPT PARAMETERS

Lists the OPT parameters that define the workload promotion:

  • BLWLTRPCT(%)—specifies how much of the CPU capacity is to be used to promote blocked workloads
    This parameter does not influence the amount of CPU service that a single blocked address space or enclave is given. Instead, it influences how many different address spaces or enclaves can be promoted at the same point in time. If the value that is specified with this parameter is not large enough, blocked workloads might need to wait longer than the time interval defined by BLWLINTHD.
    This value can be a number between 0 and 200, where 200 represents 20.0%. 2
  • BLWLINTHD—specifies the threshold time interval in seconds for which a swapped-in address space or enclave must wait before being considered to be blocked and eligible for promotion 2

PROMOTE RATE

Lists the rate per second of blocked dispatchable work units:

  • DEFINED—defined rate per second of blocked dispatchable work units that might get promoted in their dispatching priority; calculated as follows:
    SUM(SMF70PMI)/SUM(SMF70SAM)
  • ACTUAL—actual rate per second of blocked dispatchable work units promoted in their dispatching priority during the reporting interval; calculated as follows:
    SUM(SMF70PMU)/SUM(SMF70SAM)

WAITERS FOR PROMOTE

Number of address spaces and enclaves found blocked according to OPT parameter BLWLINTHD:

  • AVG—average number found blocked during the reporting interval; calculated as follows:
    SUM(SMF70PMW)/SUM(SMF70SAM)
  • PEAK—highest number found blocked during the reporting interval; calculated as follows:
    MAX(SMF70PMP)

1 For all of the fields in this section, N/A will print if data is not available for a given field.

2 An asterisk (*) following the parameter indicates that the value changed during the reporting interval.

Processor summary field descriptions

The table below describes each field in the Processor Summary section of the CPU Utilization Report.

Field

Description

PROCESSOR

  • CORE—core ID if LOADxx PROCVIEW CORE parameter is specified or CPU ID if LOADxx PROVIEW CPU parameter is specified
  • THREAD—Id of the thread running on the core.
    This field is blank if the LOADxx PROCVIEW CPU parameter is specified.
  • TYPE—type of CPU

PERCENT OF TOTAL TIME

  • ONLINE—time that the CPU was online
  • LPAR BUSY—LPAR CPU utilization
  • MVS BUSY—MVS CPU utilization
  • PARKED—CPU was parked

SMT

  • PROD %—core productivity %: the capacity in use relative to the maximum capacity during core busy time

    Note

    When the % is equal to 100%, all threads on the logical core are executing (for the processor type that has MT Mode = 1, this % is always 100%). If it is less than 100%, at least one thread on a logical core is in wait state some of the time.

  • UTIL %—core utilization %: the percentage of the maximum core capacity that is used during the interval

    Note

    This equals SMT PROD % multiplied by LPAR BUSY %.

LOG PRCR SHARE %

Percentage of a physical processor the logical processor is entitled to, calculated based on the processor's weight relative to the weights of all LPARs and the number of shared physical processors

HIPRDISP PRIORITY

The HiperDispatch priority at the end of the reporting interval /* drop presents for consistency of other field description */

Values show can be HIGH, MEDIUM, LOW, or N/A. If the priority changed during the reporting interval, an asterisk (*) is printed immediately to the right of the value.

I/O INTERRUPTS

  • RATE—I/O interrupt rate per second of the CPU
  • % TPI—percentage of I/O interrupts handled by the Test Pending Interrupt instruction

TOTAL/AVERAGE

Total or average value of several fields for each CPU type

SIMULTANEOUS MULTITHREADING

  • CPU TYPE—type of processor (CP or zIIP)
  • MODE— maximum active threads per logical core

  • AVG MAX CF— average maximum capacity factor, which represents the amount of work a multithreading core (MT = 2) can complete, relative to a non-multithreading core (MT = 1)

    Note

    When MT=2, the theoretical highest max capacity factor is 2. However, the realistic value is workload dependent and varies over time. For batch workload, the value could be as low as 1.0; for Online Transaction Processing (OLTP) workload, the value could be up to 1.4.

  • AVG CF—average capacity factor, which represents the amount of work a multithreading core (MT = 2) actually completed relative to a non-multithreading core (MT = 1)
  • AVG THREAD DENSITY—average number of threads executing during the core busy time
