NODE SWAP RATE : 2.3 1 CAUSE:MEMORY
(1) CPU TYPE: The type of CPU that is being measured.
(2) CPU COUNT: The total number of processors in the node. The figures in the
illustration show that the node sampled has 4 CPUs and that GPA can handle
up to 16.
(3) TOTAL MEMORY: The total number of megabytes of memory in the node.
The node illustrated has a total of 32 megabytes of memory.
(4) VOLUME COUNT: The total number of disk volumes in the node. The node
has 9 volumes.
(5) STATIC PCBS: The number of static process control blocks on the node.
This figure tells you how many steady-state processes were active on all CPUs
during the measurement period analyzed by GPA.
(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.
