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.

frames required is based on the
number of LPARs and Logical
processors on the system. These
frames must be contiguous. This
indicates that data may not be
reported for all logical CPUs.

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.
34 22 Unsigned 2 SYTCUG_CPUCFGCT Specifies the number of logical
CPUs for this level-2
configuration that are in the
configured state.
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.
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.
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.
