LPAR CPS

The number of standard central processors (CPs) on the logical partition (LPAR) at the end of the defined Monitor III gatherer time interval (called MINTIME). This value does not include ZIIPs. This value is from Resource Measurement Facility (RMF) field CPUG3_PRCON.

Field Name: QWOSLNCP

LPAR CPU UTILIZATION

The percentage of the MINTIME time interval during which RMF reported that the entire LPAR was in use, averaged for a single processor. This value is calculated using Resource Measurement Facility (RMF) field CPUG3_LOGITI.

Field Name: QWOSLPRU

DB2 SUBSYS CPU UTILIZATION

The percentage of the MINTIME time interval during which RMF reported that all Db2® address spaces were in use, calculated for a single processor.

Field Name: QWOSDB2U

LPAR PAGE-IN RATE

The PAGE-IN rate (%) for the LPAR. This value is always set to 0.

Field Name: QWOSLPIR

DB2 SUBSYS PAGE-IN RATE

The PAGE-IN rate (%) for the Db2 subsystem. This value is set to 0.

Field Name: QWOSDPIR

LPAR REAL STOR (MB)

The total real storage in the LPAR, in MB. This value is derived from RMF field GEIRPOOL_VE, which is the number of online real storage frames.

Field Name: QWOSLRST

DB2 SUBSYS USED REAL STOR (MB)
The real storage used by Db2 subsystems, in MB. This value is the sum of the following values for all Db2 address spaces in the LPAR, converted to MB:
  • The number of frames for swapped-in users. This value is derived from RMF field ASIFMCT_VE.
  • The number of frames for idle users. This value is derived from RMF field ASIFMCTI_VE.

Field Name: QWOSDRSU

LPAR VIRT STOR (MB)
The total virtual storage in the LPAR, in MB. This value is the sum of the following values for all address spaces in the LPAR:
  • The number of frames for swapped-in users. This value is derived from RMF field ASIFMCT_VE.
  • The number of frames for idle users. This value is derived from RMF field ASIFMCTI_VE.
  • The number of auxiliary slots. This value is derived from RMF field ASIAUXSC_VE.

Field Name: QWOSLVST

DB2 SUBSYS USED VIRT STOR (MB)
The virtual storage used by Db2 subsystems, in MB. This value is the sum of the following values for all Db2 address spaces in the LPAR, converted to MB:
  • The number of frames for swapped-in users. This value is derived from RMF field ASIFMCT_VE.
  • The number of frames for idle users. This value is derived from RMF field ASIFMCTI_VE.

Field Name: QWOSDVSU

LPAR FREE REAL STOR (MB)

The free real storage in the LPAR, in MB. This value is derived from RMF field GEIRAFC, which is the number of available real storage frames.

Field Name: QWOSLRSF

DB2 MSTR CPU UTILIZATION

The percentage of the MINTIME time interval during which RMF reported that the Db2 MSTR address space was in use, calculated for a single processor.

Field Name: QWOSMSTU

LPAR FREE VIRT STOR (MB)
The free virtual storage in the LPAR, in MB. This value is the sum of the following values, converted to MB:
  • The total real storage in the LPAR (QWOSLRST)
  • The number of currently available slots (RMF field GEISLTA)

Field Name: QWOSLVSF

DB2 DBM1 CPU UTILIZATION

The percentage of the MINTIME time interval during which RMF reported that the Db2 DBM1 address space was in use, calculated for a single processor.

Field Name: QWOSDBMU

UNREFERENCED INTERVALS

The Unreferenced Interval Count (UIC). This value is RMF field GEIAHUIC_VE.

Field Name: QWOSLUIC
