4 End the performance measurement.
5 Generate the performance measurement report.
Step 1. Set up the trace command
Before you initialize and run performance measurements, the current trace
command (the last trace command entered) must be properly set up.
1 Increase the trace depth to the maximum number by entering:
display trace depth 512
In general, you want to give the SPMT as many trace states as possible to
post-process to increase statistical accuracy. Also it is important that "time" be
counted by the analyzer; otherwise, the SPMT measurements will not be
correct.
2 Choose to make either activity measurements or duration measurements.
•
To make activity measurements (which measures activity as a percentage of all
activity, the current trace command should be the default), enter:
trace counting time
The default trace command triggers on any state, and all captured states are
stored. Also, since states are stored "after" the trigger state, the maximum
number of captured states appears in each trace list.
You can use trace commands other than the default. You can qualify trace
commands any way you like to obtain specific information. However, when
you qualify the states that get stored in the trace memory, your SPMT results
will be biased by your qualifications; the percentages shown will be of only
those states stored in the trace list.
