6.2 Record Descriptions
The CA MICS Hardware and SCP Analyzer uses SMF record types
70 through 79, which are written by the RMF (Resource
Management Facility). Following are brief descriptions of
these records:
TYPE 70 - RMF Processor Activity
The type 70 records processed by CA MICS are CPU, PR/SM,
and ICF Activity (subtype 1), and Cryptographic Hardware
Activity (subtype 2).
o Type 70 subtype 1 record contains CPU measurement data.
It reports CPU wait time and the serial and version
numbers, as well as the number of I/O interrupts and
the number of interrupts for each processor. It
indicates the number of jobs and the percentage of jobs
in the following states:
- IN - Tasks in real memory on the SRM IN queue.
- IN-READY - Tasks in real memory and ready to
execute.
- OUT-WAIT - Tasks not in real memory that are waiting
before they will be ready to execute.
- LOGICAL-OUT-READY - Tasks logically swapped out
but not yet physically swapped out that are now
ready to execute.
- LOGICAL-OUT-WAIT - Tasks logically swapped out but
not yet physically swapped out that are waiting.
It recognizes five different types of jobs: batch,
TSO, started task, ASCH, and USS. For each type, the
minimum, average, and maximum number of users in the
recording interval are captured.
It also contains the PR/SM and ICF information used to
track logical partitions configuration and utilization.
o Type 70 subtype 2 record contains measurement data for
cryptographic coprocessors and accelerators, as well as
selected Integrated Cryptographic Service Facility
(ICSF) activities.
TYPE 71 - RMF Paging Activity
The type 71 record contains Paging and Swapping
measurement data. Swapping is the primary way the MVS SRM
deals with resource shortages or over-utilization.
Information regarding CSA, LPA, SQA, LSQA, and private
areas is reported. This information includes the minimum,
average, and maximum frames used in these areas for both
fixed and pageable frames.
Type 71 record also contains paging information. For CSA,
LPA, Private VIO, and Private non-VIO areas, RMF records
the number of pages read in, the number of pages written
out, the number of pages reclaimed, and shared page group
activity. From this information and the duration of the
recording interval, a number of different paging rates are
calculated.
TYPE 72 - RMF Workload Activity and Storage Data
The type 72 record contains workload measurement data.
o Type 72 subtype 1 record contains data pertaining to
MVS systems that are using the Workload Manager in
compatibility mode.
For these systems, the overall system workload is
divided into groups called Control Performance Groups.
These can be subdivided into performance periods. The
service priorities for each performance group and each
performance period can be specified individually by the
data center if desired. For each period of each group,
the type 72 subtype 1 records contain data regarding
the resources used during the RMF recording interval.
RMF also provides Report Performance Groups. It should
be noted that the information captured for Control
Performance Groups is also counted in Report
Performance Groups. This "multiple-counting" can make
the analysis of workload data difficult.
o Type 72 subtype 3 record contains data pertaining to
MVS systems that are using the Workload Manager in goal
mode. These records are written for each service or
report class defined in the active service policy, and
include the goals and actual measured values for each
class.
CPU data contained in the type 72 records is in CPU
service units, not CPU seconds. This data can be
converted to CPU seconds by multiplying by the coefficient
appropriate for model and type of CPU. I/O and memory
utilization information is also captured in this record.
The number of ended transactions and the total elapsed
time of these transactions are also recorded.
TYPE 73 - RMF Channel Path Activity
The type 73 record contains physical and logical channel
activity measurement data. The data contains information
for each channel path indicating the type of channel and
channel busy time.
TYPE 74 - RMF Activity of Several Resources
The type 74 records processed by CA MICS are Device
Activity (subtype 1), Cross-system Coupling Facility
Activity (subtype 2), USS Kernel Activity (Unix System
Services) (subtype 3), CF/XES Activity (Coupling
Facility/Cross-System Extended Services) (subtype 4),
Cache Subsystem Activity (subtype 5), and FICON Director
Statistics (subtype 7).
o Type 74 subtype 1 records contain information for each
device about the number of Start Subchannels (SSCHs) or
Start I/Os (SIOs) for the device, the number of I/O
requests deferred, the device active time, connect
time, disconnect time, pending time, and the number of
allocations in effect on the device.
o Type 74 subtype 2 record contains information for its
MVS system on the amount of traffic to, from, and
within the MVS system; the number of signals sent to
and from each remote system, group, and member; and the
signaling path connecting the local system to all
remote systems.
o Type 74 subtype 3 record contains system-wide
information about Unix System Services (USS)
utilization, including user and process load,
inter-process communication, memory map, and shared
library measurements.
Note: Unix System Services was previously known as
OpenEdition MVS.
o Type 74 subtype 4 record contains information on the
Coupling Facility such as name, amount of storage
installed and used, and number and utilization of
processors. It contains the names of the other systems
in the sysplex connected to the CF, names and storage
resources of all structures allocated in the CF, and
detailed information identifying the cross-system
request activity to and from the MVS system. It also
describes the hardware paths between the MVS system and
the other structures in the sysplex.
o Type 74 subtype 5 record contains information on the
Cache Subsystem such as control information, return
codes from the interfaces, cache statistics at the
device, RAID rank, and control unit level.
o Type 74 subtype 7 record contains configuration and
statistics for FICON directors (switches) and ports.
o Type 74 subtype 8 record contains capacity and
performance statistics for Enterprise Disk Systems'
adapters, extent pools, and ranks.
TYPE 75 - RMF Page/Swap Data Set Activity
The type 75 record contains Page/Swap Data Set Activity
measurement data. The data contains information for each
page or swap data set. Information captured includes the
number of pages transferred, the number of I/O requests,
and the number of slots available and used for each data
set.
TYPE 76 - RMF Trace Activity
The type 76 record contains trace measurement data. The
data contains information for each field traced.
Information captured includes the field name and its last
value.
TYPE 77 - RMF Enqueue Activity
The type 77 record contains enqueue measurement data. The
data contains information for each device that was
enqueued during the RMF recording interval. Information
captured includes the current owner, the waiting users,
and the queue length for each enqueue event.
TYPE 78 - RMF Virtual Storage and I/O Queuing Activity
The type 78 records are the I/O Queuing Activity record
for pre-3090 processors (subtype 1), the Virtual Storage
Activity record (subtype 2), and the I/O Queuing Activity
record for 3090 and later processors (subtype 3).
o Type 78 subtype 1 record contains information on the
I/O configuration, I/O activity rates, and queue
lengths recorded for logical control units (LCUs) for
pre-3090 processors.
o Type 78 subtype 2 record contains information
concerning the amount of virtual storage reserved for
the CSA, MLPA, FLPA, PLPA, SQA, and nucleus, both below
and above the 16 MB line. The amount of storage
allocated for SQA is recorded by subpool and, for CSA,
by subpool and storage key. SQA expansion into CSA is
also recorded. Private virtual storage usage
information is recorded for jobs specified with the RMF
Monitor I VSTOR option.
o Type 78 subtype 3 record contains information on the
I/O configuration, I/O activity rates, and queue
lengths recorded for logical control units (LCUs) for
3090 and later processors. This record also contains
measurements pertaining to the IOPs (I/O processors)
for these processors.
TYPE 79 - RMF Monitor II Activity
The type 79 record contains RMF Monitor II measurement
data. RMF Monitor II is often run to diagnose a specific
problem or to gather more detailed data. Type 79 records
are only generated when RMF Monitor II is run as a
background session. The type 79 subtype records processed
by CA MICS are Address Space Resource (subtype 2), Real
Storage/Processor/SRM (subtype 3), Reserve (subtype 6),
and Domain Activity (subtype 10).
o Type 79 subtype 2 record contains measurements on CPU
time, EXCP count, paging statistics, fixed frames used,
and hiperspace pages used for given address spaces.
Its data reflects systems using the Workload Manager in
goal mode.
o Type 79 subtype 3 record contains measurements on real
storage and expanded storage usage for some storage
categories, UIC count, processor utilization, and some
of the SRM queues on a system-wide basis.
o Type 79 subtype 6 record contains information on the
RESERVE macros that were issued. This can be very
useful in a shared DASD environment. Included in the
information recorded is the volume serial number, the
job that issued the reserve, major and minor resource
names, and the status of the reserve.
o Type 79 subtype 10 record contains information
pertaining to SRM domains such as multiprogramming
levels, SRM queue lengths, domain contention index, and
domain average service rate.
