Java 2 Platform, Enterprise Edition (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 WebSphere Application Server-specific components, for example, and thread pools.
The
following diagram shows how the PMI and J2EE Performance Data Framework fit
into WebSphere Application Server.
