SMF Type 72 Record (Subtype 4) z/OS 2.1

This table shows the record layout for type 72 SMF records
(RMF Workload Activity and Storage Data z/OS 2.1).

List of other SMF record layouts available.
List of sample SMF reports.

Purpose: Record type 72 has several subtypes.

Subtype 4 — Data Storage is written from the Monitor III data gatherer for each service class period of each service class defined in the active service policy. It has these sections:

Service class period data section Contains Monitor III specific using and delay counts and storage frame counts for each service class period.

Swap reason data section Contains swap reason information.

It's easy to report on SMF 72 data!

We have a low-cost 4GL report writer especially for SMF files. It's called Spectrum SMF Writer.

Spectrum SMF Writer handles the difficult SMF record parsing for you automatically. You just specify which fields you want to see.

Spectrum SMF Writer also converts the arcane date and time fields and reformats them into an attractive report.

Plus, Spectrum SMF Writer can export SMF data as comma delimited files to use on your PC.
