(6)
DYNAMIC PCBS: The number of dynamic process control blocks on the
node. This figure represents processes that were started and
stopped during the measurement period analyzed by GPA. (These
processes are also known as transients).
(7)
OUT OF BALANCE CPU COUNT: The number of processors on the
node that GPA has found to be relatively over- or underutilized,
hence out of balance.
(8)
MOST BUSY CPU: The most utilized processor on the node, that is, the
one with the highest percentage busy time.
(9)
LEAST BUSY CPU: The least utilized processor on the node.
(10)
AVG CPU BUSY: The average percentage busy time of all processors
on the node. The maximum value expected is the recommended
target utilization for this type of processor.
(11)
AVG DISK VOLUME BUSY: The average percentage busy time of all disk
volumes on the node.
(12)
AVG DISK PROCESS BUSY: The average of the percentage busy times
of all disk processes running on the node.
(13)
% - RECOMMENDED RESOURCES: The extent to which the node is
being utilized in relation to the maximum recommended (100 percent)
level. The value for this parameter is derived by dividing the AVG CPU
BUSY time (Item 10 above) by the maximum recommended utilization
level. For most CPUs, the maximum recommended utilization level is
60 to 75 percent busy, depending on the CPU type.
(14)
NODE SWAP RATE: The total number of page swaps per second for all
of the processors on the node. Each page swap represents a page
(2048 bytes) of data or code that a processor is forced to transfer
from disk to memory. GPA considers a node swap rate greater than 1
to be excessive and indicates on this line the cause for such a
condition (memory shortage or load imbalance).
