Default Parameters for CassNodeDetTest

This test helps administrators to figure out the count of the nodes that are unavailable and unreachable. In addition, this test also reports the number of nodes that joined the cluster, left the cluster and migrated to another cluster. Using this information, administrators can figure out the nodes that are frequently unreachable and initiate further investigation to avoid the nodes from being unreachable too often.

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

• 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.

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.
