SMF global recording interval

The SMF global recording interval is a recording interval that is available globally to SMF, RMF™, and other requestors. The installation can specify the length of the SMF global recording interval which can be from 1 through 60 minutes; the system default is 30. Specify the length using the INTVAL parameter.

The SMF global recording interval is always synchronized with some part of the hour. The installation can specify that the SMF global recording interval be synchronized with the beginning of the hour (00 minutes past the hour) or any number of minutes past the hour up to 59; the system default is 00. Specify the synchronization value using the SYNCVAL parameter.

Example: Assume the installation wants the SMF global recording interval to have a length of 15 minutes and to be synchronized with 15 minutes past the hour, which means that the SMF global recording interval ends at 15, 30, 45, and 60 minutes past the hour. To establish this interval, code the following statements in the SMFPRMxx parmlib member:

    INTVAL(15)
    SYNCVAL(15)
