Enterprise Java Beans workspace

This workspace displays data provided by the Enterprise Java Beans attributes.

This workspace reports information about each Enterprise Java Bean (EJB) defined for an EJB container.

The workspace provides information about these beans that relates to their identity, instrumentation level settings, creation and destruction of bean objects, response times, invocations, calls, and rates for retrievals, returns, and discards.

Important:
  • This workspace reports blanks for resource data on the first invocation if PMI data collection is configured for on-demand sampling (that is, if your site set configuration value Resource Data Collection Method to On Demand) or if you have not yet run applications that generate PMI resource data. To report resource data in this workspace after installing and configuring the data collector, use the WebSphere® administrative console to set the appropriate PMI instrumentation level.
  • Because of high processor usage, the monitoring agent provides on-demand sampling by default. To activate PMI monitoring, you must first select this workspace and then select it again later. Each time you select the workspace, it displays the data collected during the interval between selections.
The predefined workspace contains the following items:
  • Worst Method Response Times bar chart, which shows the worst response times (in milliseconds) for methods invoked by each bean instance
  • Highest Method Invocation Rates bar chart, which shows the methods that are invoked most often by each bean instance
  • Enterprise Java Beans report, which shows performance information about each EJB deployed to the application server. This report displays information about bean activity, including the rates at which beans are being instantiated and destroyed

Accessing the Enterprise Java Beans workspace

You access this workspace from the EJB Containers workspace. To list the EJBs for all containers, use one of the following procedures:
  • From the primary IBM® PureApplication™ Software Monitoring Portal menu, click View > Workspace > Enterprise Java Beans.
  • Within the Navigator, right-click the EJB Containers entry; then, from the menu, click Workspace > Enterprise Java Beans.
To see the EJBs referenced by a specific EJB container, use the following steps:
