Default Parameters for CassHintTest

By closely monitoring the Casssandra Database node, this test helps administrators to figure out if the hinted handoff is enabled or not. In addition, this test reports the total number of hints that the node needs to be updated with and the number of hints that are active for replay. If there is an abnormal increase in the count of hints, administrators may infer that there is a potential database performance degradation.

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

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

• Specify the port at which the JMX listens for requests from remote hosts in JMX REMOTE PORT text box. Ensure that you specify the same port that you configured in the management.properties file in the (JAVA_HOME)\jre\lib\management folder used by the target application.

• If JMX requires authentication only (but no security), then ensure that the JMX USER and JMX PASSWORD parameters are configured with the credentials of a user with read-write access to JMX. To know how to create this user, refer to Monitoring Cassandra Database document.

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

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

• Once the above value is 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.
