KM5 MultiThreading Details attributes

This attribute group provides the details for agent KM5TDAGT.

Core ID The logical core identification. Valid value is a 2-byte integer.

Core Online% The percentage of time the logical core was online. Valid value is a 4-byte integer with a range of 0-100.

Core Priority In HiperDispatch mode, logical processors have a High, Medium or Low share of the physical processor. Valid value is a 4-byte integer.

Core Share% The percentage of a physical processor that the logical processor core is entitled to use. Valid value is a 4-byte integer with a range of 0-100.

Without HiperDispatch, the processing weight is equally divided between the online logical processors/threads.

In HiperDispatch mode, logical processors/threads have a High, Medium or Low share of the physical processor. The share percentage is the average value for the reporting interval, whereas High, Medium or Low indicates the HiperDispatch priority at the end of the reporting interval.

Core Type The core type (CP or zIIP). Valid value is a character string with a max length of 4.

LPAR Busy% The average percentage of the online time that the logical core was dispatched by the LPAR. Valid value is a 4-byte integer with a range of 0-100.

For a dedicated partition when LOADxx PROCVIEW CORE is in effect on hardware that supports MultiThreading:

LPAR BUSY TIME% = (MT Core LPAR Busy Time / Online Time) * 100 otherwise: LPAR Busy Time% = ((Online Time - Wait Time) / Online Time) * 100.

For a non-dedicated partition when Wait Completion is NO: LPAR Busy Time% = (Partition Dispatch Time / Online Time) * 100.

The partition dispatch time is the elapsed time that PR/SM dispatched this logical core during the interval.

For a non-dedicated partition when Wait Completion is YES: LPAR BUSY TIME% = ((Partition Dispatch Time - Wait Time) / Online Time) * 100.

LPAR Name Name of the LPAR. Valid value is a character string with a maximum length of 8.

Managed System Managed system name where this data is collected. Valid value is a character string with a maximum length of 32. It has the format: <plexname>:<smfid>:MVSSYS. <plexname> is the sysplex this LPAR resides in. <smfid> is the system's SMF identifier.

MT Productivity% The percentage of the maximum core capacity that was used in the reporting interval while the logical core was dispatched to physical hardware. Valid value is a 4-byte integer with a range of 0-100.

When MT % PROD equals 100% and LOADxx PROCVIEW CORE parameter is in effect, all threads on the core are executing work and all core resources are being used. If MT% PROD is less than 100%, the core resources were dispatched to physical hardware but one or more threads on a logical core were in a wait because they had no work to run.

If the LOADxx PROCVIEW CPU parameter is in effect, 'Unavailable' is displayed.

MT Utilization% The percentage of the logical core's maximum core capacity that was used in the reporting interval. Valid value is a 4-byte integer with a range of 0-100.

MT % UTIL = MT Core Productivity * TIME % LPAR BUSY.

If the LOADxx PROCVIEW CPU parameter is in effect, 'Unavailable' is displayed.

SMF ID SMF ID as defined in the IEASYM or IEASYS PARMLIB members. Valid value is a character string with a maximum length of 4.

System Name Name of the z/OS image. Valid value is a character string with a maximum length of 8.

Thread MVS Busy% The average percentage of the online time that a logical processor/thread was busy. Valid value is a 4-byte integer with a range of 0-100.

MVS BUSY TIME % = ((Online Time - Wait Time - Parked Time) / Online Time - Parked Time) * 100.

The MVS view of CPU time is not meaningful if the logical processor is parked during the entire reporting interval. In this case, 'Unavailable' is shown.

Thread Number The zero-based thread number representing a logical CPU running on the logical core. Valid value is a 2-byte integer.

Thread Parked% The percentage of time that the thread/logical processor was parked. Valid value is a 4-byte integer with a range of 0-100. In HiperDispatch mode, processors with a low amount of physical processor share may be parked. That is, they are not dispatched by z/OS and do not attempt to run work. Without HiperDispatch, processors are not parked and 'Unavailable' is shown.
