| Job | Job name (SMF30JBN) |
| Step Number | Step number (SMF30STN) |
| Step Name | Step name (SMF30STM) |
| Substep | z/OS Unix Substep (SMF30SSN) |
| End Time | The time the step ended (SMF30DTE + SMF30TME) |
| Job Number | The job identifier JOBnnnnn, STCnnnnn, TSUnnnnn etc. (SMF30JNM) |
| Type | The type of work JES2, STC, TSO, OMVS etc.(SMF30WID) |
| System | The system that wrote the record |
| Class | The job class (SMF30CL8) |
| Program | Program name (SMF30PGM) |
| Job Step | The name of the step that invoked the procedure (SMF30PSN) |
| Status | Step Status (SMF30STI). "Flushed" if the step was not executed, or various other errors. |
| Elapsed | Step 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) |
| TCB Time | Standard CPU time (SMF30CPT) |
| SRB Time | SRB CPU time (SMF30CPS) |
| EXCP Count | I/O blocks transferred. (SMF30TEP or SMF30TEX) |
| Connect Time | I/O device connect time (SMF30TCN) |
| Init. TCB | Initiator TCB CPU time (SMF30ICU) |
| Step Init. TCB | Initiator TCB CPU time during step initialization (SMF30ICU_Step_Init) |
| Step Term. TCB | Initiator TCB CPU time (SMF30ICU_Step_Term) |
| Init. SRB | Initiator SRB CPU time during step termination (SMF30ISB) |

| Accounting 1-9 | The first 9 accounting fields for the step listed separately. (SMF30ACT) |
