One standard header (standard SMF record header) is output for each record. One self-defining section is also output for each record.

Table. Standard header and self-defining section
Offsets		Field name	Length	Format	Description
0	0	SMFRSLEN	2	binary	Length of the SMF record including the SMF header (maximum size: 32,756).
2	2	SMFRSSEG	2	binary	Segment descriptor.
4	4	SMFRSFLG	1	binary	System indicator. Bit 0 1: Subsystem identification comes after system identification. Bit 1 1: Record subtypes are valid. Bit 2 0: Reserved. Bit 3-6 1111: Version identification (MVS/SP version 4 or later). Bit 7 0: Reserved.
5	5	SMFRSRTY	1	binary	Record type.
6	6	SMFRSTME	4	binary	Time since midnight (in hundredths of a second) when the record was moved to the SMF buffer.
10	A	SMFRSDTE	4	packed	Date (in the form of 0cyydddF) when the record was moved to the SMF buffer. c is 0 for 19`xx`, and 1 for 20`xx`, yy is the current year (0-99), ddd is the current day (in 1-366), and F is a sign.
14	E	SMFRSSID	4	EBCDIC	System identification.
18	12	SMFRSSSI	4	EBCDIC	Subsystem identification.
22	16	SMFRSSTY	2	binary	Record subtype. 1 (LOST): Lost information 2 (LDEV): LDEV information 3 (MPU): MP unit information 4 (PGRP): Parity group information 5 (PORT): Port information 6 (MPRANK20): Information about the top 20 resources with the highest MP usage 7 (PARM): Parameter information
For all self-defining sections
