The CA MICS Hardware and SCP Analyzer uses SMF record types
70 through 79, written by the RMF (Resource Management
Facility), and the SMF type 113 subtype 2 record written by
the CPU Measurement Facility (CPU MF) Hardware
Instrumentation Services (HIS). 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 The 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 The 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 system
resource manager deals with resource shortages or
overutilization.
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.
The 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, 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, Storage Data, and
Serialization Delay
The type 72 records processed by CA MICS are Workload
Activity (subtype 3), and Serialization Delay (subtype 5).
o The type 72 subtype 3 record contains data pertaining
to systems that are using the Workload Manager. 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.
o The type 72 subtype 5 record contains serialization
data at the system and address space levels for
different types of suspend locks, GRS enqueues, and GRS
latches. While the control section contains
system-wide delays, the data sections contain
serialization delay data for up to twenty address
spaces sorted by total contention time.
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), FICON Director
Statistics (subtype 7), and Enterprise Disk System
Statistics (subtype 8).
o The type 74 subtype 1 record contains 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 The type 74 subtype 2 record contains information for
its system on the amount of traffic to, from, and
within the 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 The 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 The 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 system. It also
describes the hardware paths between the system and the
other structures in the sysplex.
o The 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 The type 74 subtype 7 record contains configuration and
statistics for FICON directors (switches) and ports.
o The type 74 subtype 8 record contains capacity and
performance statistics for Enterprise Disk Systems'
adapters, extent pools, and ranks.
TYPE 75 - RMF Page Data Set Activity
The type 75 record contains Page Data Set Activity
measurement data. The data contains information for each
page 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 Virtual Storage Activity
record (subtype 2) and the I/O Queuing Activity record
(subtype 3).
o The 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 The 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).
This record also contains measurements pertaining to
the IOPs (I/O 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), and Reserve (subtype
6).
o The 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.
o The 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 The 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.
TYPE 113 - Hardware capacity, reporting, and statistics
o The type 113 subtype 2 record contains CPC hardware
event counter information, recorded for each online
z/OS logical processor while dispatched on physical CPC
processor chips. Included in the information is the
number of CPC cycles, instruction counts, level 1 cache
miss sourcing, translation lookaside buffer activity,
cryptographic processor usage, and other information
useful in determining how efficiently workloads exploit
the CPC hardware cache and memory architecture.
