Java Management Extensions (JMX) is a framework that enables tools for managing and monitoring applications through Managed Bean (MBeans) objects.

You can retrieve metrics about a Cassandra cluster via JMX as well as perform actions on the cluster (for example, set compaction throughput). In fact, nodetool commands query the nodes via JMX on port 7199.

When you enable JMX authentication, you are securing access to the cluster so only authenticated administrators can query cluster metadata or perform actions on nodes.

Previously, JMX authentication could only be configured with password and access files. Since DSE 5.1, DSE Advanced Security provided support for JMX authentication integrated with DSE Unified Authentication so both LDAP and Cassandra internal authentication is now possible. Cheers!
