Negative Contributing Factors to Memory Subsystem Score

Example 4-37 is a detailed report displaying the negative factors that contribute to the

memory subsystem score.

The negative contributing factors to the Memory Score are the following:

(1) Detail Negative Contributing Factors to CPU Score: Shows how the CPU

subsystem score is degraded from 100% to the final resulting score due to the

problems detected. These problems are represented by the following negative

factors:

(2) Hi Swap: CPUs that have a swap rate greater than the limit swap rate for this

CPU type. A negative score gets added to the score according to how high above

the limit the swap rate is.

(3) Memory, Mem/Tr., or Trans: Based on the swap rate and the transient rate of

the CPU, memory shortage and/or transient problems are detected. The score is

subtracted according to how severe the problems are.

(4) Disp: The dispatch rate of a CPU is over the dispatch rate limit for this CPU

type.

(5) OofBal: The difference of a processor percentage busy time from the average

percentage busy time of all processors on the node is greater than the tolerance

level.

(6) Overbsy: This is a problem when the percentage busy time of a processor is

above the maximum percentage busy time suggested for this type of processor.

Notes on Memory Subsystem Score: Good = 90% thru 100%

Fair = 76% thru 89%

Poor = 1% thru 75%

(1) Hi Swap: A processor with swap rate higher than the swap rate limit.

(2) Memory: A processor that experiences memory shortage.

(3) Tr/Swap: A processor that has high transient rate and high swap rate.
