Default Parameters for JEUSThrPoolTest

This test monitors the stateful container and reports the number and nature of methods that were invoked on each container. In the process, the test reports the status of the stateful session beans - whether they have just been created, are in the ‘ready’ state, are in the ‘passivate’ state, or have been removed from the container. Additionally, this test also reveals insights on the EJB beans and EJB objects in each statefull container.

This page depicts the default parameters that need to be configured for the JEUSThrPoolTest test.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• To enable the eG agent to communicate and continuously monitor the target JEUS server, the eG agent should be configured with the credentials of the user with administrator privileges on the server. In highly-secure environments, administrators may not want to expose the credentials of the user possessing administrator privileges. In such environments, for monitoring the JEUS server, administrators have an option to create a new user on the JEUS server and assign administrator privilege to that user. The steps to create a new user with administrator privilege are explained in the Monitoring JEUS Server document. This user should also be granted permission to access the JNDI objects on the server such that the eG agent can pull out performance metrics from the JEUS server. To know how to grant permission to access the resources, refer to the Monitoring JEUS Server document.

• Confirm the Password by retyping it in the CONFIRM PASSWORD text box.

• To collect metrics from the target server, the eG agent should be configured to use JMX to connect to the JRE used by the target server and pull out the performance metrics. By default, JMX support is enabled for the JRE used by the target server. The JMX connector listens on port 9736, by default. Therefore, type 9736 as the LISTENER PORT. However, if the host is configured with multiple sever instances, then you should specify the port number at which the JMX listens in your environment. Ensure that you specify the same port that you configured while creating the listener (if required) using the JEUS WebAdmin Console. To know the details on the listener port, refer to the Monitoring JEUS Server document.

• The export name is the reference name of the RMI connector that is to be used as a JMX connector. The procedure to obtain the export name is detailed in the Monitoring JEUS Server document. Specify the name of the export against the EXPORT NAME parameter.

• Provide the name of the sever instance that is being monitored in the Server Name text box. Also, ensure that the JVM monitoring is enabled for the target server. To obtain the name of the server instance, refer to the Monitoring JEUS Server document.

• Once the above values are provided, click on the UPDATE button to register the changes made.

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz*” and $port will be changed to “80” when configuring a test.
