Subtype 1

Subtype 1 of record type 113 contains event counter deltas for IBM® System z10™ or later CPCs. You can calculate its location in the SMF record using the following formula:

(address of record type 113 + offset value in field SMF113DOF)

Subtype 1 records are CPU Start of change

or core

specific. For each hardware data event collection cycle:

If one or more CPU counter sets are being collected (see the MODIFY HISPROC command), the system creates one subtype 1 record for each active CPU. If one or more core counter sets are being collected (see the MODIFY HISPROC command) in addition, each core counter set will be recorded from one CPU on each core.
If no CPU counter sets are being collected (see the MODIFY HISPROC command) and one or more core counter sets are being collected (see the MODIFY HISPROC command), the system creates one subtype 1 record for one active CPU on each core.

Each event counter represents the number of times a specific event has occurred from the start of the current hardware data event collection cycle or since the previous SMF Type 113 subtype 1 record was written. The system captures the valid counters and places them in the appropriate counter data slot, based on the counter event. If a counter data slot is zero, either the counter event is not defined or the counter event has not occurred in the current collection cycle. For example, counter event 0 is located in the 1st counter data slot, and counter event 9 is in the 10th slot.
