The Private Storage Usage Report tracks the use of virtual
storage at a monthly, weekly, daily, hourly, or detail level.
REPORT OPTIONS
The Private Storage Usage Report supports standard time
selection options as well SYSID selection and external data
selection. The main selection criteria will likely be the
JOB name. Normally, one or more reports will be produced for
each job specified. These options are discussed in Section
2.5.6.
This report can be produced in two formats:
o OVERVIEW
o TRENDING
OVERVIEW FORMAT
The OVERVIEW format presents a series of variables dealing
with allocated and free private storage, both above and below
16MB. Figure 2-169 shows the hourly form of the report,
using the OVERVIEW format. In the hourly form of the report,
data from one day is displayed by hour using the DAYS
time-span of the MVS Virtual Storage Private Usage File
(SCPVSU).
OVERVIEW FORMAT DATA ELEMENTS
The elements reported are divided into the following
categories:
o Job Statistics
o Average Region Size Values
o Average Map
o Average Values
o Average Subpool Alloc < 16M
With the exception of Average Subpool Allocations, all
categories include usage values above and below 16MB.
JOB STATISTICS
Job Statistics include both the number of SAMPLES and
INTERVLS used in the report.
SAMPLES: The number of RMF samples used in the input data.
INTERVLS: The number of RMF recording intervals used in the
data.
AVERAGE REGION SIZE VALUES
Average Region Size Values include measurements related
directly to the user region size and pertain to the amount of
storage requested, but not necessarily used.
JCL The amount of storage requested via the REGION
REQUESTED: parameter in the JCL. This value is derived from
the VSUAREGR element.
ASSIGNED The amount of storage assigned via exits. These
>< 16M: values are found in the VSUAURAH and VSUAURAL
elements.
AVERAGE MAP
LSQA/SWA/ The amount of storage allocated for LSQA and SWA
229/230: subpools. These values are found in the VSUAALSH
and VSUAALSL elements.
FREE LSQA/ The amount of storage in the largest free block
SWA/229-30: of the LSQA and SWA subpools. These values are
found in the VSUABLSH and VSUABLSL elements.
FREE USER The amount of storage in the largest free block
REGION: of the user region subpools. These values are
found in the VSUABUSH and VSUABUSL elements.
ALLOC. The amount of storage allocated for the user
USER region subpools. These values are found in
REGION: the VSUAAUSH and VSUAAUSL elements.
SYSTEM The amount of storage allocated in each user
REGION: region for system (overhead) functions.
AVERAGE VALUES
FREE BYTES The amount of storage of free pages of LSQA and
LSQA-230: SWA subpools. These values are contained in
the VSUAFLSH and VSUAFLSL elements.
GETMAIN The largest amount of storage that can be
BYTES: obtained via a GETMAIN macro. These values are
found in the VSUAGMLH and VSUAGMLL elements.
AVERAGE SUBPOOL ALLOC. < 16M
Average Subpool Alloc. < 16M includes the measurements of
the amount of virtual memory allocated to various subpools
below the 16MB line.
SP xxx: The amount of storage allocated to subpool x.
These values are found in the VSUAxxxL elements,
where xxx is one of the following: 000, 229,
230, 236, 237, 251, 252, and 255.
Additionally, it is possible to optionally produce all of the
above-reported elements with MINIMUM/MAXIMUM values to
provide for detailed analysis. This option is only
applicable to reports using the OVERVIEW format, however.
