Performance monitoring is an activity in which you collect and analyze data about the performance of your applications and their environment. The product collects data on run-time and applications through the performance monitoring infrastructure (PMI). This infrastructure is compatible with and extends the JSR-077 specification.
In WebSphere® Extended Deployment, a PMI module for each partition active in the cluster is created. Also provided are features to query the most active partitions in a user specified period.
An example using the partitioning facility performance monitoring functionality is provided in the management section. This example sequence demonstrates the WPFKeyBasedPartitionSample.ear application shipped with WebSphere Extended Deployment, and the source code is included.
