PMI and J2EE 1.4 Performance Data Framework

 

J2EE 1.4 includes a Performance Data Framework that is defined as part of JSR-077 (Java 2 Platform, Enterprise Edition Management Specification).

This framework specifies the performance data that must be available for various J2EE components. WebSphere PMI complies with J2EE 1.4 standards by implementing the J2EE 1.4 Performance Data Framework.

In addition to providing statistics that are defined in J2EE 1.4, PMI provides additional statistics about the J2EE components, for example, servlets and enterprise beans, and WAS-specific components, for example, thread pools and workload management.

The following diagram shows how the PMI and J2EE Performance Data Framework fit into WebSphere Application Server.
