+ ADD MEASUREMENT file-name
+ LIST CPU *
+ ADD PLOT CPU-BUSY-TIME
+ LIST PLOT
The plot that Measure displays shows the busy time for each CPU on the node
at each of the specified measurement intervals over the entire measurement
period. (For a detailed discussion of Measure plots, see the Measure User’s
Guide.)
b. From the Measure plot, determine the busiest one- to three-hour period for the
system. This is the period for which you should run the GPA analysis.
Note
For a valid analysis, the GPA analysis period should be at least one hour long.
5. If you plan to run GPA on a system other than the one being analyzed, copy the
active MEASFH file to the Measure data subvolume. You can then move the
MEASFH file along with the Measure data files to the system on which you will be
running GPA.
To find the active Measure files, enter:
5> STATUS $XM00
The system responds with status information showing the subvolume in which the active
files are located. For example, the following shows that the active Measure files are in
the subvolume SYS00:
Process Pri PFR %WT Userid Program file Hometerm
$XM00 0,50 199 P 001 255,255 $SYSTEM.SYS00.MEASCTL $BMTP.#TERM2
6. Create the three structured data files GPA uses for its analysis as follows:
a. At the TACL prompt, enter:
6> MEASCOM
b. When the MEASCOM prompt (+) appears, enter the following commands line
by line:
+ ADD measfile, [MEASFH, measfh]
+ SET REPORT FORMAT STRUCTURED, ZERO-REPORTS INCLUDE,
FROM xx:xx, TO yy:yy
+ LIST CPU *
+ LIST PROCESS *
+ LIST DISC *
+ LIST SERVERNET * (Optional, used only if the operating
system is G02 or later.)
Note that the inclusion of MEASFH, measfh on the ADD measfile line above
is required only if the version of the MEASFH file you are using to create the
