SMF Type 74 Record (Subtype 4) z/OS 1.13

This table shows the record layout for type 74 SMF records
(RMF Activity of Several Resources).

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

Purpose: Record type 74 has several subtypes.

Subtype 4 — Coupling Facility Activity
One record is written for each coupling facility by each member in the sysplex.

Local coupling facility data section One per record; contains path and subchannel data collected from each local system.

Connectivity data section One per sysplex member connected to the coupling facility. This member list is used by the Postprocessor to verify that it has a complete set of SMF records for creating sysplex-level reports for this coupling facility. This section is gathered on only one system in the sysplex (RMF’s sysplex master gathering) and is available only if the status flag SMF744FFLG in the local coupling facility data section indicates that the coupling facility was connected to the system at the end of the interval.

Storage coupling facility data section One per record; contains global data that is only collected once for the sysplex.

Structure data section One for each structure allocated in this facility, whether or not the facility has an active connection. This section is gathered on only one system in the sysplex (RMF’s sysplex master gathering) and is available only if the status flag SMF744FFLG in the local coupling facility data section indicates that the coupling facility was connected to the system at the end of the interval.

Request data section One for each structure in this facility that has had an active connection at some time during the interval.

Processor utilization data section One for each processor (CP, not IOP) within the respective coupling facility.

Cache data section Several sections for each request data section are possible, depending on applications using the coupling facility.

Remote facility data section One section for each duplexing coupling facility with various signal counters.

Note: Except where otherwise indicated, the coupling facility values are snapshots at the end of the recording interval.

It's easy to report on SMF 74 data! (Jump to sample reports)

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.

Spectrum SMF Writer - the 4GL SMF Report Writer.

Sample Report from SMF 74 Subtype 4 Records
Showing RMF Coupling Activity Over an Interval

The sample SMF report below was created with Spectrum SMF Writer, the low-cost 4GL SMF report writer.

This report reads as input the SMF file and selects just the type 74 RMF Activity records with subtype = 4. (See SMF 74 record layout.) Each of these SMF records contains multiple Request Sections. We normalize these sections in order to easily print the same report information from each request section. We then print a report line for each Request Section, showing various statistics relating to synchronous and asynchronous requests during the interval. It also shows a count of certain requests for which no resource was available.

In this report, we take advantage of several of Spectrum's special formatting options. The BIZ ("blank if zero") option suppresses 0 values, which can clutter up a report. Also, since the SMF744SASQ field encompasses a wide range of values, we used a "scaled" type of picture to format it. Spectrum automatically displays a value with the appropriate K, M, G, ... suffix as necessary. This technique lets you display more data (in smaller columns) when it is not essential to know the exact value of a field.

We also used another technique to squeeze more data columns into the report. Since the identical Sysplex and System names appear for hundreds of consecutive lines, we moved those 2 fields from the detail report lines up into the page titles. We page-break on those fields to insure that the data on each page comes from a single Sysplex-System.

All of this with just a couple of dozen lines of code!
