MRSYTCUG Prolog
DSECT NAME - SYTCUG
FUNCTION - Map a Monitor record.
LOCATED BY -
Through the Monitor Control Area
REFERENCED CONTROL BLOCKS -
MRRECHDR Monitor Record Header
NAME - MRSYTCUG
DESCRIPTIVE NAME - Monitor Sample Record
Domain 0 - System Domain
Record 15 - Logical CPU Utilization Data (Global)
DESCRIPTION - Global description of logical CPU utilization in
a LPAR environment. This record contains only data
of global nature and exists only when the system is
running under control of the PR/SM feature. For
descriptions of individual logical partitions and
their logical CPUs, see the MRSYTCUP (Domain 0,
Record 16) record.
NOTE: Data in the STSI fields is produced when the necessary
architecture is present for the STSI instruction.
When this is not present the field values will be 0's.

monitor support available. The
enhanced LPAR monitor support
allows for reporting of large

the MRSYTCUP record (D0/R16).
..1. .... SYTCUG_LCUT204S Indicates the storage page(s)
required to obtain the enhanced
LPAR statistics was unavailable
for this interval. The number
of pages required is based on
the number of LPARs and Logical
processors on the system. These
pages must be contiguous. This
indicates that data may not be
reported for all logical CPUs.
...1 .... SYTCUG_LCUT204E Indicates enhanced LPAR
monitor support available as
described for SYTCUG_LCUT204S
with the addition of support
for secondary processors such
as zIIPs, zAAPS, and IFLs.

26 1A Unsigned 2 SYTCUG_LCUTPCCT Number of CPUs in the
physical system, or in the
physical partition if the
system is running in physically

STSI 2.2.2 fields
Offsets
Dec Hex Type Len Name (Dim) Description
28 1C Unsigned 2 SYTCUG_LPNUMBER LPAR Number of the level-2
configuration. This number is
unique to this configuration
from all other level-2
configurations provided by the
same LPAR hypervisor.
30 1E Character 1 * Reserved and available for
IBM use.
31 1F Bitstring 1 SYTCUG_CPUCHAR Describes the characteristics
of the logical CPUs that are
provided for the level-2
configuration.
32 20 Unsigned 2 SYTCUG_CPUCOUNT Specifies the total number of
logical CPUs that are provided
for this level-2 configuration.
This number includes all of the
logical CPUs that are in the
configured state, the standby
state, or the reserved state.
Count does not include any
secondary processors
34 22 Unsigned 2 SYTCUG_CPUCFGCT Specifies the number of
logical CPUs for this level-2
configuration that are in the
configured state. Count does
not include any secondary
processors
36 24 Unsigned 2 SYTCUG_CPUSTNBY Specifies the number of
logical CPU's for this level-2
configuration that are in the
standby state. A logical CPU is
in the standby state when it is
in the level-2 configuration,
is not available to be used to
execute programs, and can be
made available by issuing
instructions to place it in the
configured state. Count does
not include any secondary
processors
38 26 Unsigned 2 SYTCUG_CPURESVD Specifies the number of
logical CPU's for this level-2
configuration that are in the
reserved state. A logical CPU
is in the reserved state when
it is in the level-2
configuration, is not available
to be used to execute programs,
and cannot be made available by
issuing instructions to place
it in the configured state.
Count does not include any
secondary processors
40 28 Character 8 SYTCUG_LPARNAME Specified the name of this
level-2 configuration.
48 30 Unsigned 4 SYTCUG_LPARCAF The LPAR Capabiltiy
Adjustment Factor specifies the
amount of the underlying
level-1 configuration
capability that is allowed to
be used for this level-2
configuration by the LPAR
hypervisor. The maximum value
is 1000, and the fraction of
level-1 configuration
capability is determined by
dividing the CAF value by 1000.
52 34 Unsigned 2 SYTCUG_CPUDEDCT Specifies the number of
configured state logical CPUs
for this level-2 configuration
that are provided using
dedicated level-1 CPUs
54 36 Unsigned 2 SYTCUG_CPUSHARD Specifies the number of
configured state logical CPUs
for this level-2 configuration
that are provided using shared
level-1 CPUs.
