Note the FTP server SMF user exit is called before an SMF type 118 record that contains information about an FTP server session is written to the SYS1.MANx data set. The user exit allows site specific modifications to the record and controls whether the record is written to the SYS1.MANx data set.
Note that the exit is called only for type 118 records. SMF type 119 FTP records must use the system-wide SMF user exits (IEFU83, IEFU84, and IEFU85) to obtain this same functionality. For information on these SMF user exits, see z/OS MVS System Management Facilities (SMF).
