PMI and J2EE v1.4 Performance Data Framework

Java EE 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 Java EE components. WebSphere PMI complies with Java EE 1.4 standards by implementing the Java EE 1.4 Performance Data Framework.

In addition to providing statistics that are defined in Java EE 1.4, PMI provides additional statistics about the Java EE 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 Java EE Performance Data Framework fit into WAS.
