Drill through to the following reports: CPU: MIPS Used - LPAR Level by WLM Importance; CPU: Over/Under Share Weight - CPC by LPAR
Report-specific prompts: cpu serial no; processor type; optimization run

The Optimization Metadata table contains the following information:

OPTIMIZATION RUN: The name that is used for the execution of the LPAR weight optimization.
MODEL VERSION: The version of the optimization model.
HOUR START: The start hour of the dates that are used in the LPAR weight optimization run.
HOUR END: The end hour of the dates that are used in the LPAR weight optimization run.
EXECUTION TIMESTAMP: The execution start time of this optimization run.
EXECUTION DURATION: The length of time that the optimization run took to run.
OBJECTIVE: The total objective value of this optimization model.

The LPAR Weight Optimization Run - LPAR Information table contains the following information:

LPAR NAME

The name of the LPAR.

LPAR PRIORITY

The priority of the LPAR. Higher numbers mean that an LPAR has a higher priority.

FIXED WEIGHT

The fixed weight value for the LPAR, if specified. If the value is "N/A", it means that the weight is not fixed and it is optimized by the LPAR weight optimization run.

TARGET WORKLOAD IMPORTANCE LEVEL

The importance level of the target workload’s boundary of this LPAR.

A NULL value means that the WLM importance level does not need to be considered. The target workload is considered to be the total workload multiplied by the value of the TARGET WORKLOAD IMPORTANCE LEVEL % column.

A value of 0 to 6 means that the workloads under the importance level number are considered as the target workload for this LPAR. Also, it means that a certain percent (the value of the TARGET WORKLOAD IMPORTANCE LEVEL % column) of the importance level is considered as the target workload for this LPAR.

TARGET WORKLOAD IMPORTANCE LEVEL %

The percentage that is used in the target workload calculation.

When TARGET WORKLOAD IMPORTANCE LEVEL is null, then it is the percentage of the total workload that should be considered as the target workload.

When TARGET WORKLOAD IMPORTANCE LEVEL is a number from 0 to 6, then it is the percentage of the TARGET WORKLOAD IMPORTANCE LEVEL workload that should be considered as the target workload.

OBSERVED WEIGHT

The average observed weight of the dates and hour range considered in the optimization run.

OPTIMIZED WEIGHT

The optimized weight that is the result from the LPAR Weight Optimization run.

MAX OVER TARGET WORKLOAD

The maximum value that the target workload is over the optimized weight for this LPAR. The value is a percentage of the capacity of the shared pool of this processor type.

MAX OVER TOTAL WORKLOAD

The maximum value that the total workload is over the optimized weight for this LPAR. The value is a percentage of the capacity of the shared pool of this processor type.

SUM OVER TARGET WORKLOAD

The sum of the amount that the target workload is over the optimized weight for each time interval for this LPAR. The value is a percentage of the capacity of the shared pool of this processor type. Because it is a sum value for each time interval, it is possible that the value can be larger than 100%.

SUM OVER TOTAL WORKLOAD

The sum of the amount that the total workload is over the optimized weight for each time interval for this LPAR. The value is a percentage of the capacity of the shared pool of this processor type. Because it is a sum value for each time interval, it is possible that the value can be larger than 100%.

The LPAR Weight Optimization Run – Dates Information table contains the following information.

DATE: The dates used for the optimization run.

The LPAR Weight Optimization Run – Sub Objectives Information table contains the following information.

SUB OBJECTIVE NAME: The name of each sub objective for the LPAR Weight Optimization model.
SUB OBJECTIVE WEIGHT: The weight or punishment value for each sub objective for the optimization run.
