This test helps determine the transaction load on the GlassFish Enterprise server, detect transaction rollbacks, and receive regular updates on transaction status.

The default parameters associated with this test are as follows:

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

• In the HOST text box, specify the hostname of the storage device.

• Specify the port at which the specified HOST listens in the PORT text box.

• To collect metrics from a GlassFish Enterprise server, the eG agent monitoring that server should be configured to use JMX to connect to the JRE used by the server and pull out the metrics of interest. By default, JMX support is enabled for the JRE used by the GlassFish Enterprise Server. The JMX connector listens on port 8686 by default. Therefore, type 8686 as the JMX REMOTE PORT. If JMX listens on a different port in your environment, then specify the same here. To know the port at which JMX listens, open the domain.xml file in the <GLASSFISH_INSTALL_DIR>\Sun\AppServer\domains\domain1\config directory and look for the code block shown below:

  <jmx-connector accept-all=“false” address=“0.0.0.0” auth-realm-
  name=“admin-realm” enabled=“true” name=“system” port=“8686”
  protocol=“rmi_jrmp” security-enabled=“false”>

  The port number specified against the port parameter in the code block above refers to the JMX REMOTE PORT.

• By default, the JMX connector on the GlassFish Enterprise Server requires authentication. To enable the eG agent to use JMX therefore, you need to configure the agent with the credentials of a user who is authorized to use JMX. Typically, the GlassFish administrator has the right to use JMX. You can hence configure the JMX USER and JMX PASSWORD parameters with the credentials of the administrator. However, if you prefer not to expose the credentials of an administrator owing to security considerations, you can use the credentials of any other user with access rights to JMX. To know the name of such a user, open the domain.xml file in the <GLASSFISH_INSTALL_DIR>\Sun\AppServer\domains\domain1\config directory and look for the code block shown below:

  <jmx-connector accept-all=“false” address=“0.0.0.0” auth-realm-
  name=“admin-realm” enabled=“true” name=“system” port=“8686”
  protocol=“rmi_jrmp” security-enabled=“false”>

  The user name specified against the auth-realm-name parameter in the code block above can be configured as the JMX USER, and the password of that user can be specified against JMX PASSWORD.

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

• The JNDINAME is a lookup name for connecting to the JMX connector. By default, this is jmxrmi. If you have registered the JMX connector in the RMI registry using a different lookup name, then you can change this default value to reflect the same.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the Update button will register the changes made.

When changing the configuration for specific servers, a "*" beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a "$" or contain a series of "*". A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
