Negative Contributing Factors to CPU Score
The CPU Subsystem Score is based on CPU utilization, load balancing, and performance
of the processors on the node. Example 4-35 is a detailed report displaying the
negative factors that contribute to the CPU subsystem score.

NEGATIVE CONTRIBUTING FACTORS:
Hi Swap - Swap Rate Greater Than Limit Memory - Memory Shortage
Mem/Tr. - Memory and Transient Problem Trans. - Transient Problem
Disp. - Dispatch Problem OofBal - CPU Out of Balance
Overbsy - CPU Overbusy Problem
Notes on CPU Subsystem Score: Good = 90% thru 100%
Fair = 75% thru 89%
Poor = 1% thru 74%
(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.
