SMF record type 88 (hexadecimal 58)

This record contains information about the system logger. z/OS® provides a sample reporting program, IXGRPT1, in SYS1.SAMPLIB. Monitor the following key values, which you can obtain from type 88 records:

Average buffer size
This size is not reported directly. Divide the number of bytes written by the number of writes completed to calculate this value.
Structure-full events
If you see these events, the amount of space in the coupling facility is insufficient. Review your sizing assumptions and provide more space.
