IPC Traffic Analysis
For each processor on the node, the diagram shows:
Below this information is data for each disk volume for which the processor is the
primary CPU, including:
This diagram (Example 3-11) shows the same information as the previous one does
except that it displays the GMS information instead of the controller information. This is
because the controller is obsolete on operating system G02 and later.
IPC Traffic Analysis
For ServerNet-based systems, there is one IPC Traffic Analysis report (Example 3-12)
for each CPU in the system, which provides a summary of IPC (Inter-Processor
Communication) traffic to and from each processor. To generate this report, you enter
the following commands at the MEASCOM prompt before you run GPA.
Before you start the measurement, enter:
+ ADD SERVERNET *
(1) CPU: The CPU’s identification number.
(2) TYPE: The processor type.
(3) BUSY: The percentage busy time.
(4) MMGR: Pages of memory owned by the memory manager.
(5) The identification number (in octal) of the volume’s controller with an
arrowhead pointing toward the number of the backup processor.
(6) The name of the volume.
(7) The percentage busy time for the disk processes associated with the volume,
followed after the first slash (/) by the number of memory pages held by the disk
process, and followed after the second slash by the number of cache calls per
second for the volume.
