CPU (Report control statements)

The CPU control statement requests the CPU Utilization Report.

CPU
[MSUDIST=YES|NO]
[MSUDTAIL=4HOURMSU|INTVLMSU|INTVLWLM|TIME]
[MSUDTPCT=10|nnn]
[PRSMCHNG=MANYRPTS|ONERPT]
[MAXLPARS=256|nnnn]

The CPU Analyzer statement uses data collected by the CPU Extractor control statement.

Parameters

The parameters for the CPU control statement are as follows:

MSUDIST=

specifies whether the Rolling 4-Hour MSU Usage Distribution section is produced; the default is YES

MSUDTAIL=

specifies that the MSU Usage Detail section and the sorting order of the recording intervals are produced

  • 4HOURMSU—The recording intervals are sorted in decreasing 4-hour MSU/hour (MSU/hour consumed in the four-hour period up to the end of the recording interval).
  • INTVLMSU—The recording intervals are sorted in decreasing interval MSU/hour (MSU/hour consumed during the recording interval).
  • INTVLWLM—The recording intervals are sorted in decreasing % capped by WLM during the recording interval.
  • TIME—The recording intervals are sorted in chronological order.

MSUDTPCT=

specifies that the topnnn % of recording intervals are formatted in the MSU Usage Detail section when 4HOURMSU, INTVLMSU, or INTVLWLM is specified for the MSUDTAIL parameter;nnn is in the range 1 to 100; the default is 10

MSUDTPCT is ignored when MSUDTAIL is not specified or when MSUDTAIL=TIME is specified.

PRSMCHNG=

specifies whether one or many reports are produced if changes are detected in PR/SM configuration

  • MANYRPTS—If changes are detected in PR/SM configuration, multiple reports are produced, one for each configuration. Examples of PR/SM configuration attributes include number of partitions, weight (share) of any partition, number of logical processors of any partition, and number of physical processors.
  • ONERPT—A single report is produced, ignoring all PR/SM configuration changes; the default.

MAXLPARS=

specifies the maximum number of LPAR entries in the LPAR sections of the report

  • 129—Up to 129 LPAR entries can appear in the LPAR sections of the report.
  • 256— Default value.
  • nnnn—Any number in the range 129 to 1024.

Examples

The following examples illustrate the use of the CPU control statement.

Example
CPU MSUDTAIL=4HOURMSU

This example produces one CPU Utilization Report with MSU Usage Detail section containing the top 10% busiest of recording intervals sorted by four -hour MSU/hour consumed in the four-hour period up to the end of the recording interval.

Example
CPU PRSMCHNG=MANYRPTS

This example produces multiple CPU Utilization Reports if changes are detected in PR/SM configuration.

Example
CPU

This example produces one CPU Utilization Report, even if changes are detected in PR/SM configuration.
