Columns

 

Column

Description

Job

Job name (SMF30JBN)

Job Number

The job identifier JOBnnnnn, STCnnnnn, TSUnnnnn etc. (SMF30JNM)

Descendants

The number of descendants of this job entry. Descendants are entries for unix work that created separate SMF type 30 records (and usually ran in a separate address space) but was created by this job.

Type

The type of work JES2, STC, TSO, OMVS etc.(SMF30WID)

Sysplex

The Sysplex of the system that wrote the record (SMF30SYP)

System

The system that wrote the record

Class

The job class (SMF30CL8)

Started

The time the initiator selected the job (SMF30STD + SMF30SIT)

Ended

The time the job ended (SMF30DTE + SMF30TME from the subtype 5 record.)

Elapsed

Job elapsed time (end time - initiator select time)

Derived CPU

CPU time calculated from the TCB and SRB CPU service values.

This provides a more accurate value than the CPU time fields from the SMF 30 record, which are rounded to 1/100th of a second.

The value includes Normalized zAAP and zIIP time which means that the value will exceed the total of actual CP + zAAP + zIIP time if the zAAP/zIIP is faster than the regular CP.

CP

CPU Time on standard processors ( SMF30CPT + SMF30CPS + SMF30ICU + SMF30IIP + SMF30RCT + SMF30HPT)

zIIP

CPU time on zIIP processors (SMF30_TIME_ON_zIIP)

zIIP on CP

CPU time for zIIP eligible work spent on standard CPUs (SMF30_TIME_zIIP_ON_CP)

zAAP

CPU time on zAAP processors (SMF30_TIME_ON_IFA)

zAAP on CP

CPU time for zAAP eligible work spent on standard CPUs (SMF30_TIME_IFA_ON_CP)

TCB Time

Standard CPU time (SMF30CPT)

SRB Time

SRB CPU time (SMF30CPS)

Init. TCB

Initiator TCB CPU time (SMF30ICU)

Init. SRB

Initiator SRB CPU time (SMF30ISB)

I/O Interrupt Time

CPU time used to process I/O interrupts (SMF30IIP)

RCT CPU

CPU time for the region control task (SMF30RCT)

Crypto Service Count

The number of ICSF instructions executed. (SMF30CSC)

zEDC Time

zEDC execution time (SMF30_US_ExecTime)

zEDC Queue

zEDC queue time (SMF30_US_QueueTime)

zEDC Req.

Total number of zEDC requests (SMF30_US_ComprReq)

zEDC Comp

Number of input bytes compressed (SMF30_US_Def_UncomprIn)

zEDC Decomp

Number of output bytes decompressed (SMF30_US_Inf_DecomprOut)

zEDC Comp%

Overall compression percentage (space saved) e.g. 100MB before compression, 10 MB after compression is 90% compression.

( 1 - ( SMF30_US_Def_ComprOut + SMF30_US_Inf_ComprIn ) /  ( SMF30_US_Def_UncomprIn + SMF30_US_Inf_DecomprOut ) )

Enqueue Promoted Time

CPU time consumed while enqueue promoted (SMF30CEP)

Unix CPU

Accumulated time for Unix services. z/OS will only collect data for this field when SYSCALL_COUNTS is set to YES (SMF30OST)

Highest CPU%

The highest interval CPU usage percent by a task in this address space (SMF30_Highest_Task_CPU_Percent)

Highest CPU

The name of the task that used the highest interval CPU percent (SMF30_Highest_Task_CPU_Program)
