How to Use Metrics

To use Metrics, you must set the SMFTYPE Initialization parameter to an unused SMF value from 128 to 255. This identifies a unique SMF record type to the system management facility.

Note: For more information about syntax of the SMFTYPE parameter, see the initialization parameter descriptions in the chapter "Initialization Parameters".

To locate an unused SMF record type, review the contents of SYS1.PARMLIB(SMFPRMxx). This system parameter is expected to contain a list of used SMF records types. In this example, type 129 is not defined and is available for use:

SYS(TYPE(128,132,140:144,....),
INTERVAL(SMF,NOSYNC),
NODETAIL,
EXITS(IEFU83))

To find the SMFPRMxx member name, review the contents of SYS1.PARMLIB(IEASYSxx normally IEASYS00) which contains the SMFPRMxx member qualifier. For example, SMFPRM03:

SMF=03

Note: Setting the SMFTYPE Initialization parameter to 0(zero) disables CA View SMF Metrics recording.

You can also review IBM's Initialization and Tuning Reference operating system guide in the "SMFPRMxx (system management facilities (SMF) parameters)" chapter for this and other methods to determine an unused SMF record type.
