This test reports the health of the message bus connection and helps the administrator to figure out the number of vCloud Director cells that are currently reachable and not reachable.

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, the host name of the component for which the test is to be configured has to be specified.

• Specify the port at which the specified HOST listens in the PORT text box. By default, this is NULL.

• Specify the port at which the JMX listens for requests from remote hosts in the REMOTE PORT 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 registery using a different lookup name, then you can change this default value to reflect the same.

• If JMX requires authentication only (but no security), then ensure that the USER and PASSWORD parameters are configured with the credentials of a user with read-write access to JMX.

• Confirm the password by retpying it in the CONFIRM PASSWORD text box.

• 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.
