Measure Reference Manual

The first line starts MEASCOM, the Measure command interface. The plus sign (+) is the MEASCOM
command prompt. The next two lines configure the measurement, instructing Measure to take
measurements on CPUs 5 and 6. In these commands, CPU is the entity type, and 5 and 6 are
entity specifications.
Step 2. Take the Measurement
To start the sample measurement:
3+ START MEASUREMENT MYDATA
The file name MYDATA identifies the output file—that is, the file in which the Measure performance
monitor is to save the measurement data. Each time you start a measurement, you must identify a
new or existing measurement file.
This measurement uses many defaults. You can specify options such as a starting time for the
measurement, a duration, and a measurement interval. The measurement interval causes Measure
to write counters to the data file at a specified interval rather than just at the beginning and end
of the measurement. For example, you might have counter values recorded at 30-minute intervals.
When you examine the measurement, you can see results for successive time periods, as well as
the totals.
Step 3. Examine the Measurement
To stop the sample measurement and display the results of the measurement:
4+ STOP MEASUREMENT MYDATA

The LIST command displays the results of the measurement on the screen. Each measured CPU has
its own report. The counter values appear as percentages or totals.
