4> MEASCOM
When the MEASCOM prompt appears, enter the following commands line by line:
+ 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. The new version of GPA does not require you to create the entity files. It takes the
measure collection as an input parameter and generates the necessary entity files.
