The purpose of the J2EE container interval SMF record is to record activity within a J2EE container that is located inside the WebSphere®Application Server transaction server.
This record is produced at regular intervals and is an aggregate of the activities running inside a J2EE container during the interval. This record can be used to perform application profiling, problem determination, and capacity planning.
A single record is created for each active J2EE container located in a WebSphereApplication Server transaction server within the interval being recorded. If there is more than one server instance associated with a server, a record for the container will exist for each server instance. To get a common view of the work running in the J2EE container during the interval, you must merge the records after processing.
You can specify an interval through the WebSphereApplication Server administrative console by setting server_SMF_interval_length=n, where n is the desired number of seconds.
You can activate this record by setting server_SMF_container_interval_enabled=1 (or server_SMF_container_interval_enabled=true)on the administrative console.
