JMX Resources (MBeans) for DSE Utilities

After enabling Java Management Extensions (JMX) authentication, DataStax Enterprise (DSE) utilities and other third-party tools require MBean access to execute commands. The tools use JMX MBeans to remotely gather information and execute requests.

Access is controlled using modelled hierarchy. Granting and revoking a privilege on a top level object automatically allows the same permission on all ancestors.

MBeans have the following modelled hierarchy for access control:

MBREAD, MBWRITE, and equivalents are deprecated.

Synopsis

Use the following syntax to grant access:

ALL MBEANS
```
GRANT <permission>[, <permission> ...]
ON ALL MBEANS
TO <role_name>;
```
where permissions are ALL PERMISSIONS, DESCRIBE, EXECUTE, MODIFY, and SELECT.
MBEANS <pattern>
```
GRANT <permission>[, <permission> ...]
ON MBEANS '<class_name>:name=<value>,type=<value>'
TO <role_name>;
```
where DSE supports wildcard characters in the value name to match one or more MBeans and permissions are ALL PERMISSIONS, DESCRIBE, EXECUTE, MODIFY, and SELECT.

MBEAN <name>

GRANT <permission>[, <permission> ...]
ON MBEAN '<class_name>:name=<value>,type=<value>'
TO <role_name>;

where permissions are ALL PERMISSIONS, DESCRIBE, EXECUTE, MODIFY, and SELECT.

Revoke permissions syntax:

REVOKE <permission_name>
ON <resource>
FROM <role_name>;
