The purpose of the server interval SMF record is to record activity that is running inside a WebSphere®Application Server for z/OS®. This record is produced at regular intervals and is an aggregate of the work that ran inside the server instance during the interval.
A single record is created for each server instance that has interval recording active during the interval. When a server is configured with multiple server instances, each server instance writes a record and the records from all the server instances must be merged by whoever is looking at the SMF records to get a complete view of the work that ran inside the logical server.
You can activate this record through the administrative console by setting server_SMF_server_interval_enabled=1 (or server_SMF_server_interval_enabled=true). You can specify an interval through the administrative console by setting server_SMF_interval_length=n, where n is the desired number of seconds.
