Processor Performance Chart
This chart (Example 3-6) gives the following physical and performance data for each
processor on the node analyzed:
(1)
CPU NUM
: The processor‟s identification number.
(2)
CPU TYPE
: The processor‟s type designation. All of the processors
in the example are TXPs.
(3)
MB MEMORY
: The processor‟s total memory in megabytes. Each
processor on this node has 8 megabytes of memory.
(4)
PCT BUSY: Percentage of time the processor is busy. These figures
are the basis for the levels indicated on the Processor Load Balance
Chart.
(5)
DISK PRIME: The number of volumes for which the processor is the
primary CPU.
(6)
DISK RATE: Number of disk I/O operations per second performed
on the CPU. Notice that the chart shows no disk I/Os for CPUs 1 and
3, since no volumes are primaried on these processors (see Item 5
above).
(7)
CHIT RATE: Number of cache hits per second. Here again, CPUs 1
and 3, with no volumes primaried, show no cache hits.
(8)
MSG RATE: Number of messages per second sent or received by
the processes on the CPU.
(9)
DISP RATE: Number of dispatches per second occurring on the
processor.
(10)
SWAP RATE: Number of page swaps per second taking place on
the processor. Notice in the example that CPUs 0 and 1 with their
high swap rates are contributing to the excessive swap rate for the
node (refer to Example 3-1).
(11)
MMGR PAGES: Number of 2048-byte pages in memory owned by
the memory manager. A portion of this is used to calculate cache.
(12)
PCB COUNT: Number of processes active on the CPU during the
measurement period analyzed by GPA.
(13)
TRANSIENTS: Number of processes on the CPU that were started
and stopped during the measurement period analyzed by GPA.
