CPU Subsystem Score : 76%
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.
(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.
