EJB Containers workspace

This workspace displays aggregated information about each defined EJB.

This workspace displays aggregated bean performance data for all Enterprise beans deployed to an EJB container. It also displays aggregated information for the application server that aggregates bean performance data for all Enterprise beans deployed on the application server. This workspace displays data provided by the EJB Containers attributes.

Notes:
  • 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 overhead, 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:

  • Method Average Response Time - History graph, which shows the average response time for methods invoked by the EJBs in the container
  • Method Invocation Rate - History graph, which shows the rate at which an EJB container's methods were invoked
  • EJB Containers report, which displays aggregated information for each defined EJB container that aggregates bean performance data for all Enterprise beans deployed to that container. The report also displays aggregated information for the application server that aggregates bean performance data for all Enterprise beans deployed to the application server. For example, this report displays load values, response times, and lifecycle activities for Enterprise beans

Accessing the EJB Containers workspace

To access this workspace, complete the following steps:

  1. Within the Navigator, expand Windows Systems, Linux® Systems, z/OS Systems or UNIX Systems, as appropriate for the node you are monitoring.
  2. Within the node list, expand the entry that corresponds to the node you want to select.
  3. Within that node list of monitored applications, expand the list of WebSphere agents.
  4. Within the list of available agents, expand the WebSphere application server of your choice.
  5. Within that server list of available WebSphere Application Server workspaces, click the EJB Containers entry.

Accessing the Managing Server Visualization Engine from the EJB Containers workspace

In The Tivoli Enterprise Portal access the EJB Containers workspace. You can use the Diagnostic Server Activity Display link to access the Managing Server Visualization Engine.

  1. In the EJB Containers window, right-click the choose link icon Choose link icon then click Diagnostic Server Activity Display.
  2. If this is your first time to access the Managing Server Visualization Engine during a session, you see a Welcome to the Application Monitor page.
  3. Depending on the user setup configuration in your environment you may or may not have to type your Managing Server Visualization Engine User Name and Password. If you do, you only need to log in using your User Name and Password once per session.
  4. Click OK to display the Server Activity Display page in the Managing Server Visualization engine. You can use link to diagnose application problems, for example, slow transactions or high response times.
  5. The results relate directly to the context from where you launched the link in the IBM® Cloud Pak System Software Monitoring Portal. For more information about using the Server Activity Display page and additional features, refer to the Composite Application Manager help within the Managing Server Visualization Engine Interface.
  6. To return to the previous workspace in the Cloud Pak System Software Monitoring Portal interface at any time choose from the following options:
    • From the Cloud Pak System Software Monitoring Portal desktop client, click the back arrow on your web browser.
    • From the Cloud Pak System Software Monitoring Portal browser client, click the browser back arrow.
