Type 109 SMF records

Table 1 shows the format of syslogd messages as written to SMF.

Table 1. Type 109 SMF record layout
Offsets	Name	Length	Format	Description
0(x'0')	SMF109LEN	2	Binary	Record length (maximum size 32 756). This field and the next field (total of 4 bytes) form the record descriptor word (RDW). The first 2 bytes of this field must contain the logical record length, including the RDW. The second 2 bytes which are in the following field are used for variable block spanned records. If the record is spanned, set these 2 bytes to hexadecimal zeros. Both fields must be filled in before writing the record to the SMF data set.
0(x'2')	SMF109SEG	2	Binary	Segment descriptor (see previous record length field).
0(x'4')	SMF109FLG	1	Binary	System indicators (bits and meaning when set): 0-2 Reserved 3 MVS/SP Version 4 and later. Bits 3, 4, 5, and 6 are on (*). 4 MVS/SP Version 3 and later. Bits 4,5, and 6 are on. 5 MVS/SP Version 2 and later. Bits 5 and 6 are on. 6 VS2. Bit 6 is on. 7 Reserved. Use information located elsewhere in this record to determine the MVS™ product level.
5(X'5')	SMF109RTY	1	Binary	Record type: 109 (X'6D')
6(X'6')	SMF109TME	4	Binary	Time since midnight, in hundredths of a second, that has elapsed since the record was moved into the SMF buffer. In record types 2 and 3, this field indicates the time that the record was moved to the dump data set.
10(X'A')	SMF109DTE	4	Packed	Date when the record was moved into the SMF buffer. In the form of 00yyddF or 0cyydddF [where c is 0 for 19xx and 1 for 20xx, yy is the current year (0-99), dd is the current day (1-366), and F is the sign]. In record types 2 and 3, this field indicates the date that the record was moved into the dump data.
14(X'E')	SMF109SID	4	EBCDIC	System identification (from the SID parameter).
18(X'12')	SMF109LOG	4096	EBCDIC	System logging daemon (syslogd) messages.
