Can't See all the the MBeans?
As each MQ object is exposed as a JMX MBean, you may have exceeded the AppDynamics default 1000 MBean count limit if you have a lot of queues.

Per Domain Limit
With some app servers, it is possible to exceed the MBean count limit for a domain. The limit is controlled by the jmx-max-mbeans-to-load-per-domain node property. The default value is 1000.
Attribute Limit
With some app servers, it is possible to exceed the MBean attribute limit. The limit is controlled by the jmx-max-mbean-attributes-to-load node property. The default value is 1000.
Solution: Increase the Limit
1. Register the appropriate limit node property from the Node Dashboard. Use these steps: Add a Node Property,
2. Enter an Integer value greater than the default value.
3. Restart the JVM/server.
