SMF CPU Time in Step and Interval Level Files

The MICS Batch and Operations Analyzer creates step/interval level files from SMF type 30 Common Address Space Work step and interval records (subtypes 2, 3, and 4).

Each observation in the step/interval files contains CPU time utilization metrics for the program executing in the interval or step.
The following are the
MICS
step and interval files:
  • BATPGM - Batch User Program Activity File
  • BAT_TS - SMF User TSO Activity File
  • BAT_ST - System Task Program Activity File
  • BAT_TP - APPC/MVS TP Activity File
  • BAT_OE - Open Edition/MVS Program File
  • BAT_SA - System Address Space Activity File
There are numerous CPU time measurements recorded in the SMF type 30 record. Some CPU time metrics are subsets of other recorded metrics. It is important to understand which CPU time fields are subsets of others to prevent overstating the CPU time used by a step or interval.
The remainder of this section lists all of the CPU time measurements found in the step and interval files, along with a brief description. The metrics are separated into the following three groups:
  • Standalone CPU Time Data Elements
  • Subset CPU Time Data Elements
  • Computed CPU Time Data Elements
