The below information is data for each disk volume for which the processor is the
primary CPU, including:
(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.
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 *
After the measurement is taken, enter:
+ LIST SERVERNET *
The latter command creates a structured data file named SVNET for GPA to analyze.
The IPC Traffic Analysis reports the ServerNet IPC information. This information points
out which processors create (send) and which consume (receive) messages. By
moving processes that create messages to the consuming CPUs, you can reduce
interprocess message traffic costs.
