Function: This facility allows the storage administrator to
monitor key storage indicators on a day-by-day
basis. These indicators enable the user to
project short-term storage needs, both at the
application level and the system level. The
indicators reported by this facility are also
useful for detecting problems with storage
resources that are not being used efficiently.
These reports, along with the Monthly Application
Resource Usage reports, provide both a short view
and a long view of storage capacity and
performance problems.
The ability to process data from multiple sources
makes the reports produced even more valuable.
Options allow the user to target a single storage
media, such as real DASD or HSM backup storage, or
to group data from multiple media on the same
chart. This second type of reporting is useful
when analyzing the flow of data across multiple
types of storage media.
The types of data that can be selected for
reporting include the number of data sets, amount
of space being allocated, percentages of data sets
and space in certain categories, and the amount of
allocated versus used space.
Features: Summarization options allow you to analyze the
data based on its owner (using one or more of the
CA MICS accounting fields), its SMS storage class,
its SMS management class, or its location (such as
real DASD, or HSM level 1 migration).
Data filtering allows you to include data from
selected summary groups. For example, you could
choose to report on specific departments, groups
or individuals, or on a specific SMS class.
Output reports from this facility include tabular
reports, printer plots, or color graphic plots.
When plots are requested, up to nine different
elements can be plotted on the same chart.
SMS
Issues: The ability to summarize by an SMS storage or
management class makes it easy to monitor the
short-term activity within each of your defined
classes. Many of the elements you can select for
reporting are useful for monitoring an SMS
migration effort, or to make sure SMS is operating
correctly after migration is complete.
ELEMENT DESCRIPTIONS
SYSID
This value appears at the top of each page and
identifies the System Identifier (system) to which
this data applies.
Media
Storage Class
Management Class
Group
The top line of each page also indicates the
summary group to which the values on this plot
apply. Depending on the report option chosen,
this summarization will be done by media (DASD,
VSAM, MIGRATE, or BACKUP), SMS storage class, SMS
management class, or based on the CA MICS
accounting codes in the data. The label to the
left of the summary value will be one of the
values shown above, depending on the summarization
option chosen.
Vertical Axis (Value)
The numeric values distributed vertically down the
left side of each page represent the scale of the
numeric values being plotted on that page. When
requesting color graphics plots, you can specify
the values that will appear on this axis. This
should be done with care, because all plots and
groups will have to adapt to the values you
specify. For printer plots, or when values are
not specified, SAS will generate the values
automatically, based on the content of the plotted
data. We suggest that these SAS defaults be used
whenever possible, as they will avoid many
potential problems. Care should also be taken
when specifying multiple elements on one plot,
that the elements chosen will have a similar range
of values.
Horizontal Axis (Date)
Plots on the horizontal axis represent the date
corresponding to the value being plotted. Each
date is presented in the format 'ddmmmyy'. The
number of entries appearing on the horizontal axis
is determined by the number of cycles of CA MICS
data specified as input to the inquiry.
Footnotes
The footnote(s) section of each graph is
important, as it indicates the names of the data
element(s) that are plotted on the graph. Up to
nine elements can be plotted on the same graph, in
which case 9 footnotes will appear at the bottom
of each page. For printer plots, an alphabetic
character A-I will appear to the left of each
description, identifying the character used on the
plot to represent that particular element. On
color graphic plots, the letter does not appear,
as the color of the footnote should correspond
with the color of the plot point/line on the
graph. If different colors do not appear for each
point and footnote, your MICF options should be
modified to specify different colors. A brief
description of the possible values in the footnote
section, and what those values represent, is given
below:
