SMF record type 92 provides reports of activities related to the z/OS® UNIX file system. The File System I/O counts displayed in the ISHELL mount table is available if type 92 subtype 5 (unmount) is active at the time the file system was mounted. To avoid the overhead associated with recording type 92 subtype 10, 11, and 14 (open, close, delete or rename), adjust the parameters in SMPFPRMxx using the TYPE or NOTYPE operands to exclude the subtype 10, 11, and 14 records.
