SMF Type 79 Record

This table shows the record layout for type 79 SMF records
(RMF Monitor II Activity - z/OS 1.11).

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

Purpose: Record type 79 is written during a Monitor II background session when feedback is requested as SMF records. It is written at each measurement interval and when the session is terminated. It contains a section that is identical for all Monitor II reports and a subtype section that is unique for each report. The subtypes are:

Subtype 1 contains information that describes address space state data (and address space state data by job name) for each address space identifier included.
Subtype 2 contains information that describes address space resource data (and address space resource data by job name) activity. The length depends on the number of devices.
Subtype 3 contains information that describes central storage/processor/SRM activity.
Subtype 4 contains information that describes paging activity.
Subtype 5 contains information that describes address space SRM data (and address space SRM data by job name).
Subtype 6 contains information that describes reserve data.
Subtype 7 contains information that describes enqueue contention data.
Subtype 9 contains information that describes device activity. The length depends upon the number of devices.
Subtype 11 contains information that describes paging data set activity. The length is variable.
Subtype 12 contains information that describes channel path activity. The length is variable.
Subtype 14 contains information that describes I/O queuing activity by logical control unit. The length is variable.
Note: Your installation may produce several type 79 subtype 14 records.
Subtype 15 contains information about IRLM long locks.
Note: The records of this subtype have no RMF product section (as indicated in field SMF79PRN) and have no Monitor II control section.

Note: All fields with format s_float have the type short format floating point.

It's easy to report on SMF 79 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.
