Figure 2-101. DASD I/O Component Analysis Report Inquiry Panel
The following is a discussion of the fields on this panel.
Timespan: The specification of whether the data is to be
taken from the DETAIL or DAYS timespan.
Cycle(s): One or more cycles of the CA MICS files
that you want to use for analysis. Because SMF
data sets are not normally dumped at exactly
midnight at most installations, a cycle from the
CA MICS file usually contains a 24-hour period
spanning two days. Hence, some other type of
selection may be required to generate a daily
report. This selection capability is provided
by the DATE and HOUR control parameters.
Database: The single-character CA MICS identifiers for the
databases you want to access.
Allow The indication of whether the database
Runtime identifier and/or the Cycles specification can
Override: be overridden at inquiry execution time.
Report by The specification of whether a report should be
time generated for each interval specified or
interval: summarized into a single report.
Minimum I/O A filter for the exclusion of low I/O activity
rate: volumes. It specifies the minimum per second
I/O rate for volume inclusion in the analysis.
This value may range between 0.001 and 999.
This allows you to exclude devices that were
either unused during the interval or received
very little use. If you use this control
parameter, the I/O filter applies to all I/O
component and shared-DASD reports.
CA MICS In addition to the Minimum I/O rate, the Shared
Element DASD I/O Component Analysis Report inquiry can
to test: test any other numeric data element in the
HARDVA File for a specific condition. This can
be used to further subset the data to be
analyzed.
Operator The boolean operator to employ - LE, LT, GT,
to employ: or GE.
Numeric
value to The value against which the data element is
test: tested.
Date: The day(s) to be used for analysis. This field
is normally used with the IOA Shared DASD
Analysis inquiry to drop the extra day from a
cycle that is due to the timing of the SMF dump.
Hour: An hour or range of hours for which data is
reported.
Zone: The specification that zone selection is to be
applied. If zone 1 definition is 8:00 a.m. to
6:00 p.m., daily reports covering that time
period can be specified by using the ZONE
field set to 1.
Sysid: The SYSID of the data to be reported.
Specify The specification that allows you to supply
extended additional report options. These options
options: include special SAS data selection statements,
non-standard input, and output files. These
options are discussed in the sections that
follow.
The operation of the time selection control parameters
depends on definitions made during the installation of
CA MICS. If you are not sure about the zone definitions
for your installation or the CA MICS database update
procedures, consult your CA MICS System Administrator.
