Warning Track Interrupt LPAR attributes

This attribute group provides warning track interrupt statistics, including metrics for both the successful and unsuccessful warning track interrupt requests, the number of SIGPs issued, and the time returned to the hardware via warning track requests.

Managed System Managed system name where this data is collected. It has the format: <plexname>:<smfid>:MVSSYS. <plexname> is the sysplex this LPAR resides in. <smfid> is the system's SMF identifier.

LPAR Name Name of the LPAR from which the data was collected.

SMFID The system management facility (SMF) identifier for this z/OS image.

Measurement Interval The time interval in .001 seconds over which the metrics were collected.

Core Type The type of core (CPU). Currently CP (standard) and zIIP are supported.

Successful WTI Count The count of warning track requests issued to the logical CPU, or logical CPU type, where z/OS returned the logical CPU to the hardware within the grace period across the measurement interval.

Successful WTI Percent The percent of warning track requests issued to the logical CPU, or logical CPU type, where z/OS returned the logical CPU to the hardware within the grace period across the measurement interval.

Unsuccessful WTI Count The count of warning track requests issued to the logical CPU, or logical CPU type, where z/OS did not return the logical CPU to the hardware within the grace period across the measurement interval.

Unsuccessful WTI Percent The percent of warning track requests issued to the logical CPU, or logical CPU type, where z/OS did not return the logical CPU to the hardware within the grace period across the measurement interval.

Undispatched WTI Time The time in microseconds that the logical CPU, or logical CPU type, was returned to the hardware across the measurement interval as a result of warning track requests.

Undispatched WTI Percent The percentage of dispatch time that the logical CPU type was returned to the hardware across the measurement interval as a result of warning track requests.

SIGP Count The count of SIGPs issued to the logical processor, or the processor class, over the measurement interval.

SIGP Rate The rate of SIGPs per second issued to the logical processor, or the processor class, over the measurement interval.

CPC Name The name of the central processing complex.

CPC Serial The 6-character CPC Serial Number; for example, 05E789.

Sysplex Name The name of the sysplex in which the monitored z/OS image is a member.

Core ID The logical core ID.

Thread Number The logical thread number, where 0 and above are valid thread numbers. A value of -1 indicates that this row of data is associated with a CPU class such as zIIP or CP.
