Monitoring performance

Performance measurements are available for service component event points, and are processed through the Performance Monitoring Infrastructure. This section describes how you would configure the process server to gather performance metrics from service component event points.

Whether you are tuning WebSphere® Process Server service components for optimal efficiency or diagnosing a poor performance, it is important to understand how the various run time and application resources are behaving from a performance perspective. The Performance Monitoring Infrastructure (PMI) provides a comprehensive set of data that explains the runtime and application resource behavior. Using PMI data, the performance bottlenecks in the application server can be identified and fixed. PMI data can also be used to monitor the health of the application server.

The PMI is included in the base WebSphere Application Server installation, and this functionality is documented in considerable detail in the WebSphere Application Server Version 6.0 Information Center. This section provides only supplemental information about performance monitoring as it relates to the service components specific to WebSphere Process Server, so consult the information in the WebSphere Application Server documentation for using PMI with other parts of the entire product.

The service component event points specific to WebSphere Process Server that can be monitored by the PMI are those that typically have ENTRY, EXIT, and FAILURE event natures. Event sources which are not defined according to this pattern are not supported; this includes business process or human task events. Events that are supported have three types of performance statistics that can be measured:
