SMF Type 23 Record
This table shows the record layout for type 23 SMF records
It's easy to report on SMF 23 data!
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.
Record length. This field and the next field (total of four bytes) form the RDW (record descriptor word). See “Standard SMF Record Header” on page 13-1 for a detailed description.
Segment descriptor (see record length field).
System indicator: Bit Meaning When Set 0-2 Reserved 3-6 Version indicators* 7 Reserved.*See “Standard SMF Record Header” on page 13-1 for a detailed description.
Record type 23 (X'17').
Time since midnight, in hundredths of a second, when the record was moved to the SMF buffer.
Date when the record was moved into the SMF buffer, in the form 0cyydddF. See “Standard SMF Record Header” on page 13-1 for a detailed description.
System identification (from the SID parameter).
Offset to product section from start of record, including the record descriptor word (RDW).
Length of product section.
Number of product sections.
Offset to system section from start of record, including the record descriptor word (RDW).
Length of system section.
Number of system sections.
Offset to SMF statistics section from start of record, including the record descriptor word (RDW).
Length of SMF statistics section.
Number of SMF statistics sections.
Subtype identification — ‘0’.
Record version number — ‘02’.
Product name — ‘SMF’.
Length of measurement interval.
Operating system release level.
MVS product name (taken from CVTPRODN).
Time and date that the interval ended for the STATUS function, in time-of-day (TOD) format, an unsigned 64-bit fixed-point number where bit 51 is equivalent to 1 microsecond. If you requested synchronized interval recording for SMF statistics, a field in other records, similar to this field, contains the same time so you can compare this record with other records generated at the end of the same interval.
System name (from the SYSNAME parameter in the IEASYSxx parmlib member).
Sysplex name (from the SYSPLEX parameter in the COUPLExx parmlib member).
Number of buffers written.
Maximum number of buffers used at one time.
Number of records written.
Amount of each buffer allocation request.
Total amount of buffer storage currently allocated (and recently used).
‘High water mark’ of buffer storage allocation.
Buffer storage maximum in effect (BUFSIZMAX binary value).
Buffer storage usage warning level in effect (BUFUSEWARN binary value).
The table above is based on the description provided by IBM in its "MVS Systems Management Facilities (SMF)" manual.
