The Historical Observations Report provides a summary of the
historical values contained in the Capacity Planning database
file. You define the structure of this report using the
Profile and Trending Analysis control screen shown in Figure
5-6.
While the principal application of these reports is intended
to be the presentation of historical data, you can also use
them to examine the behavior of the data before applying the
more detailed statistical analysis procedures provided in the
remaining chapters.
Figure 5-1 shows a sample Historical Observations Report. The
following information is shown:
SYSID: The SYSID specified by the SYSID control
parameter.
ZONE: The ZONE specified by the LVL control
parameter.
For each historical observation, the following data elements
appear in the report columns:
MONTH: The MONTH and YEAR of the historical
observation. If you specify the WEEKS timespan
when the Capacity Planning database file is
created, then the title for this column is WEEK
ENDING and the week ending dates appear in the
report. If you specify the DAYS timespan when
the Capacity Planning database file is created,
then the title for this column is DAY ENDING
and the day ending dates appear in the report.
You specify the remaining columns of the report through
parameters on the Profile and Trending Analysis control
screen. For example, the first column of the report shown in
Figure 5-1 is:
CHANNEL 1 The historical observations for the average
BUSY (%): monthly channel 1 busy values computed for ZONE
1.
