1.3 Reporting and Inquiry Facilities
The CA MICS Analyzer Option for VM/CMS provides management
reports, standard analysis reports, and exception reports
that you can either use as delivered or tailor to your
specific requirements. In addition, you may use the MICF and
standard SAS language interface to create ad hoc reports.
The standard reports and online inquiries provide concise,
comprehensive information to help you manage the VM
environment. Each type of report and reporting facility is
described on the following pages.
Management Reports
The management reports provide a concise graphical or tabular
representation of the site's processing objectives and how
well they have been met.
You define the objectives through a series of parameters,
then produce the reports during normal daily, weekly, or
monthly CA MICS processing. You can activate or deactivate
the reports for any of these timespans (daily, weekly, or
monthly).
The management objective reports described in the chart below
are delivered with the CA MICS Analyzer Option for VM/CMS.
-------------------------------------------------------------
Report Function
-------------------------------------------------------------
VM Resource Quantifies the total VM resource consumption
Consumption in seconds per hour averaged across all
processor engines in the supporting com-
puting system. The management objective to
be tracked is the average CPU time (in
seconds) consumed per day.
VM Service Quantifies the total VM service provided for
each computing system. The management
objective to be tracked is an absolute
measure of the number of VM Q1 drops that
occurred within a user-specified number of
seconds. This is represented by a chart
depicting the average Q1 service interval
time.
VM Availability Shows the availability of a VM system for
the identified time period and computing
system. The management objective to be
tracked is either the number of minutes of
uptime per hour (daily and weekly) or the
percentage uptime for the total time
available in user-defined shifts (zones) in
each month.
VM Throughput Quantifies total VM throughput in terms of
the number of scheduled interactions
processed on an hourly basis for the
identified time period and computing system
over a day, week, or several months. The
management objective to be tracked is an
average of the number of scheduled
interactions processed per hour.
Standard Analysis Reports
You can also produce a standard analysis report on VM
activity. This report provides a one page summary for a
user-specified time period that quantifies system
utilization, storage utilization, and scheduler/dispatch
activity measures. Derived from detail data, this report is
designed to produce a snapshot of key system performance
measures.
Standard analysis reports include a series of predefined MICF
inquiries. These inquiries are run on an as-needed basis and
can serve as templates for designing your own inquiries. The
predefined MICF inquiries described in the following chart
are delivered with the product.

VM IUCV/VMCF Produces a horizontal bar chart, in
User Summary descending order, of IUCV/ VMCF service
users by name, for the top n services during
a user-defined reporting period. You can
use this report to analyze which services
are experiencing heavy usage.
VM Channel Produces a tabular listing of channel
Busy Report activity by channel path identifier for a
user-specified time period, quantifying the
average percent busy and average percent of
total system channel activity for each
CHPID. You can use this listing to analyze
which CHPIDs are being heavily used.
VM Demand Produces a tabular listing, in time
Scan Summary sequence, of demand scan activity sum-
marized by a user-specified number of
minutes and a user-specified time period.
Numbers in the Emergency Pass section of the
report indicate a possible storage-
constrained environment.
VM Device Produces a tabular ranking of devices, in
Ranking Report descending order of utilization, by
subchannel identifier or device number (for
example, summarized across subchannels) for
a user-specified time period. This report
provides analysts with the device activity
information necessary to monitor which
devices are being used and at what rates.
VM IUCV/VMCF Produces, in time sequence, a listing of
Summary Report overall system activity, summarized by a
user-defined number of minutes, that covers
such measures as system utilization, active
users, and paging activity for a user-
specified period of time. You can use this
report to monitor gross system activity, to
perform post-analysis of poor system
performance periods, or to compare activity
at different times of day, for different
days of the week, etc.
VM User Produces a tabular listing of summarized
Consumption user resource consumption, for a user-
Report specified time period, ranked by CPU time
consumed, average working set size, or
virtual I/O rate.
VM User State Provides a tabular listing, in time
Summary sequence, of user states (various wait
states, running, etc.) for a user-specified
time period and summarized by a user-defined
number of minutes. You can use this report
to monitor the states in which users are
spending their time and to ascertain whether
users are often waiting on a particular
resource such as the CPU or I/O.
VM Concurrent Produces, for a user-defined time period, a
Channel Busy horizontal bar chart in which each bar
represents the number of times during the
reporting period that n number of channels
were concurrently busy. You can use this
chart to analyze whether the I/O workload is
being spread over the channel subsystem.
VM Percent Provides a horizontal bar chart in which
Channel Busy each bar represents the percent busy for a
given Channel Path ID (CHPID) for a user-
specified period of time. The chart
displays only those channel paths that
experienced some activity. You can use this
report to analyze the channel subsystem for
performance tuning and capacity control
purposes.
VM Cache Produces a tabular listing of cache usage on
Usage Report 3880-23 and 3990-3 control units, in
ascending VOLSER order, for a user-specified
period of time. You can use this report to
analyze cache usage based on volume of
activity directed to cache VOLSERs, whether
transfers to and from DASD are being avoided
by using cache, and the percentage of bytes
read from cache, from DASD bypassing cache,
and from DASD due to read misses.
VM CP-Owned Produces a tabular listing of activity on
Volume Summary CP-owned VOLSERs for the duration of the
user-specified period. You can use this re-
port to analyze page and spool activity on
CP-owned volumes, including average and
maximum slots used, I/O activity, I/O
queuing measures, interference from user
I/O, etc.
VM Device Produces a tabular listing of activity for
Utilization selected devices. It allows analysis of
individual devices, selectable by address,
VOLSER, device type, or device class. It is
useful for determining when during the day,
activity is being directed to the device,
and when device performance is degraded.
VM Cache Produces a tabular report of cache usage on
Usage Detail 3880-23 and 3990-3 control units by selected
Report VOLSERs. It allows analysis of cache use
by individual device. Separate reports are
produced for 3880-23 and 3990-3 controllers.
User Provides a tabular report of summarized
Consumption resource consumption ordered by time. It
Report allows analysis of individual virtual
(By User) machines. It is useful for tracking changes
in user activity that may adversely impact
overall system performance.
LPAR Provides a tabular report of processor usage
Utilization for logical partitions for a user-defined
Report time period. It is useful for analyzing
the distribution of processor resources
between dispatch time and management
overhead among logical partitions in a PR/SM
environment. The report also includes LPAR
configurations.
Exception Analyzer Reports
The CA MICS platform provides an Exception Analyzer that
works with CA MICS Data Integration Applications to provide
consolidated reporting of exception conditions across systems
and data sources. An "exception" is any condition that
deviates from the expected norm, or any missed objective in
system performance or service.
The CA MICS Analyzer Option for VM/CMS is delivered with
several exception tests, and you can easily add your own
tests. The exception reports produce increasing levels of
detail to address the needs of different audiences and, when
combined with exceptions from other CA MICS applications,
comprise a powerful diagnostic tool for your organization.
The Exception Analyzer Reports described in the following
chart are delivered with the product.
-------------------------------------------------------------
Report Function
-------------------------------------------------------------
Exception Provides a concise, high-level summary of
Management exceptions reported for the previous day.
Overview The report lists, in terms of severity, the
number of exceptions for each defined
management area. Designed for use by upper
management, it allows quick assessment of
the operation's stability.
Management Area Provides an hourly summary of exceptions
Exception encountered for a specified management area
(for example, performance or availability),
and the number and severity of each
exception type that occurred during an hour.
Typically, first-level managers who are
responsible for defined management areas use
this inquiry.
Severity Level Provides an hourly summary of exceptions
Exception encountered for given severity levels,
allowing quick assessment of the types of
exceptions in each level. It gives first-
level managers, performance analysts, and
system programmers an integrated report of
problems that may have affected the
site in any given hour.
Detail Exception Provides a detailed list of detected
exceptions in order of occurrence. You may
produce this report online using various
selection criteria, including a date and
time range, severity level, management area,
etc. You can use this report as background
detail for effective analysis of the
reported exceptions.
Ad Hoc Reporting Facilities
Because the specific types of information needed to manage a
large IS organization change daily, CA MICS provides
interactive capabilities that allow fast response to complex
requests. These capabilities are provided by:
o The CA MICS Information Center Facility (MICF) - MICF is
an ISPF-based panel-oriented productivity tool that allows
you to access information in the CA MICS database. When
you define input, selection criteria, and report options,
MICF dynamically builds an inquiry program that executes
in either interactive or batch mode. Then, depending on
your specific requirements, MICF either prints the inquiry
report, displays the results at your terminal, or catalogs
the results for later viewing.
o The Standard SAS Language - Because an advanced analysis
language enhances the staff's analytical capabilities and
improves the quality of decision-making, CA MICS uses SAS,
a powerful fourth generation language. SAS allows easy
data manipulation and statistical analysis and provides
coding facilities for programmers who are conducting
extensive analysis or designing new reports for IS
business applications.
The CA MICS Workstation Facility (MWF) provides an online
environment that supports SAS in both interactive and
batch modes. CA MICS uses the SAS system as a data
manager and as an advanced analysis language.
