| 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) |
