Configuring a JMX Connection to DSE using LCM

About this task

Configure a local connection or remote JMX connection to DSE using Lifecycle Manager.

Additional settings are available in jvm8-server.options and jvm11-server.options depending upon the JDK in use.

The types of JMX connections are:

Click Config Profiles from the Lifecycle Manager navigation menu.
Click the edit icon for the configuration profile you want to edit, or click Add config profile if you have not already added a config profile.
In the Config Profile pane under the Lifecycle Manager section, click jvm-server.options.

The general settings for configuring JVM options appears.
Scroll down to the JMX pane. Select the jmx-connection-type.
- To enable local JMX Connection, ensure that jmx-connection-type is set to Local-JMX - No Authentication (default).
- To enable remote JMX Connection without authentication, ensure that jmx-connection-type is set to Remote JMX - No Authentication.
  
  Using the Remote JMX - No Authentication option is not recommended because this option allows unauthenticated remote connections to DSE.
- To enable remote JMX Connection with DSE Unified Authentication, ensure that jmx-connection-type is set to Remote-JMX - DSE Unified Authentication. When using DSE Unified Authentication, by default you can access JMX using the username cassandra and the password of the cassandra role from the DSE cluster.
Click Save.

Run a configure job to apply the config profile changes.
