System ID section

This section provides information about the system (both hardware and software) at the time the usage data was collected.

Triplet information

This section is located on the record using the following triplet fields, which are located in the "self-defining" section:

Offset: SMF89SIO
Length: SMF89SIL
Number: SMF89SIN - This field is always "1" because each type 89 record that is generated has one system ID section.

Offsets		Name	Length	Format	Description
0	0	SMF89SYN	8	EBCDIC	MVS™ system name (SYSNAME from IEASYSxx).
8	8	SMF89UST	4	binary	Usage data interval START time (local, hundredths of a second from midnight). This is usually an hour value (such as 01:00:00.00) except in the case of the first record during an IPL (which reports the “IPL” time). This is different from the recording interval that is used to report on the generation of the usage records. This field and SMF89UET define the hour "bucket"that the usage data reflects. This field is only filled in for the SMF89 subtype 1 records.
12	0C	SMF89USD	4	packed	Usage data interval START Date in the form 0`cyydddF`. See Standard SMF record header for a detailed description. This field is only filled in for the SMF89 subtype 1 records.
16	10	SMF89UET	4	binary	Usage data interval END time (local, hundredths of a second from midnight). This is usually an hour value (such as 01:00:00.00). This field and SMF89UST define the hour "bucket" that the usage data reflects. This field is only filled in for the SMF89 subtype 1 records.
20	14	SMF89UED	4	packed	Usage data interval END date in the form 0`cyydddF`. See Standard SMF record header for a detailed description. This field is only filled in for the SMF89 subtype 1 records.

For the two digit LPAR ID (greater than X'F'), SMF89LPM (bit 1) is on, and SMF89LP3 contains the LPAR ID.

140	8C	SMF89MAF	30	binary	Array of multiprocessing CPU capability adjustment factors. This array contains information for only the first 15 general processors. Obtain additional processor information from RMF™ records, or issuing the STSI instruction.
170	AA	SMF89LPN	8	EBCDIC	LPAR name when SYSIB 2.2.2 is valid, when returned by the STSI instruction (such as when running under z/VM®). Bit SMF89LPV is on when the field is valid. Avoid looking at this field unless SMF89LNV is on.
178	B2	SMF89_Capacity _Change_Cnt	2	binary	The number of processor capacity changes that occurred since the previous interval or event interval. This number is greater than 1 when the number of processor capacity changes exceeded the number specified in the MAXEVENTINTRECS parmlib option.
180	B4	SMF89_RCTPCPUA _Actual	4	binary	Physical CPU adjustment factor (this is the adjustment factor for converting CPU time to equivalent service in basic-mode with all processors online). Based on model capacity rating.

Bit Meaning when set 0 SMF89_Event_Driven_Interval_RecMeaning: When on, indicates that the current record was generated as a result of an event, rather than as a result of a standard interval expiration based on time. 1 SMF89_Capacity_Data_errMeaning: When on, indicates that an error occurred while collecting the processor capacity data, therefore the following fields are unreliable: SMF89_RCTPCPUA_Actual SMF89_RCTPCPUA_Nominal SMF89_RCTPCPUA_scaling_factor SMF89_Capacity_Adjustment_Ind SMF89_Capacity_Change_Rsn 2 SMF89_PCD_Rsvd_ExistsMeaning: When on, indicates records generated on systems running z/OS® V1R7 through z/OS V1R9.
