Usage data on z/OS
This topic introduces SMF 89 subtype 1 records as a method of recording accumulated usage data on z/OS®.
Whenever an execution group (DataFlowEngine) address space starts on z/OS, the system registers the address space for usage data collection; the system writes this usage data information to SMF 89 subtype 1 records.
When the execution group address space stops, the system deregisters the address space. The data that is collected in the SMF 89 subtype 1 records does not correspond to the data that is collected by the Accounting and Statistics SMF 117 records.
The system writes the accumulated usage data at a scheduled interval, the maximum period of which is one hour. The timing of the interval is set by the INTERVAL value that is specified for the SMF address space.
The system writes any usage data that is produced by other products to the same SMF 89 subtype 1 record.

In all cases, the values are left-aligned and padded with blanks.
All execution groups that are started and stopped on a single system provide the same values when registering and deregistering. Therefore, the usage data that is written at the end of an interval in the SMF 89 subtype 1 record is an accumulation of all execution group address spaces.
