This report quantifies the total VM service provided on a
zone basis for a period of months, for each computing system.
The management objective to be tracked for evaluating the
speed and consistency for all VM activity is an absolute
measure of the number of VM Q1 drops that occurred within a
specified number of seconds.
The only user option that applies to this report is the Total
Service Objective, which is the average over all VM users
that entered queue one and were subsequently dropped within
the installation's service objective (e.g., average Q1
service within three seconds).
&VMCMSECX defines the vertical axis of the Q1 service time
report. &VMCMSEC defines the target Q1 service time.
Therefore, to measure the number of VM Q1 drops that occur
within each three-second period, code:
%LET VMCMSECX = 3.0;
%LET VMCMSEC = 1.0;
A full description of the user options is provided in Section
3.3.4.1, VM Report Options.
Figure 3-60 illustrates the Monthly VM Service Report based
on a management objective of maintaining an average VM Q1
service interval time of less than one second. The sample
report shown here quantifies the service provided with the
horizontal axis representing the zones of each month in the
report and the vertical axis charting the average VM Q1
service time in seconds, as identified in the title.
The management objective for total VM service is shown by the
dashed horizontal reference line printed across the chart.
In Figure 3-60 , the reference line is shown at the three-
second level of the vertical axis. Therefore, any zone for
which the vertical bar exceeds this reference line signals
that the VM service objective was missed for that zone of
that month.
