System management facilities (SMF) is a function of MVS that allows the collection and recording of various types of system and job-related information. This information is recorded in the form of a number of different records, which are numbered. Installations can process the SMF records with any number of application programs to analyze the data, produce reports, etc.

Two SMF records (types 26 and 57) are recorded by JES3 that contain network-related information. The type 26 record is produced at job termination time and contains various job summary information. The type 57 record is produced for each transmitted job (or SYSOUT) after successful transmission and contains summary and resource usage information related to the network processing of the job.

There are no records produced in JES3 that record information of a network management nature.
