Default Parameters for CassRdRprTest

Using this test, administrators can figure out the count of background read repairs coordinated by the node and the read repairs attempted by the node. In addition, this test also reveals the full data digests coordinated by the node. By analyzing the count of read repairs at regular intervals, administrators can figure out the erratic pattern of read repairs performed on the node and figure out the exact cause of such erratic behavior in updating the node with the latest data information.

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

• 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 cassandra-env.sh file (if the target Cassandra Database node is installed on a Unix host) or the cassandra-env.ps1 file (if the target Cassandra Database node is installed on a Windows host) in the (CASSANDRA_HOME) directory used by the target Cassandra Database node. To know how to specify the remote port, refer to Monitoring Cassandra Database document.

• 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.
